Description

控制程式管理裝置、控制裝置以及控制系統 Control program management device, control device and control system

本發明係有關一種將例如使用於工廠自動化(Factory Automation：FA)系統中的控制程式難讀化。 The present invention relates to a control program that is, for example, used in a factory automation (FA) system.

在FA系統中，配置有用以控制工場內的生產機器之動作的控制裝置(以下也簡稱為控制器)。 In the FA system, a control device (hereinafter also simply referred to as a controller) that is useful for controlling the operation of the production machine in the factory is configured.

該控制器係稱為可程式化邏輯控制器(Porgrammable Logic Controller：PLC)。 This controller is called a Programmable Logic Controller (PLC).

用以使PLC動作之控制程式係使用編程軟體並根據階梯式等語言加以作成(設計)。 The control program for causing the PLC to operate is created (designed) using a programming software in a language such as a ladder.

被作成的控制程式(例如階梯形式)係根據編程軟體而轉換為可實行的形式(指令)，並透過通訊路線而寫入到PLC。 The created control program (for example, the ladder form) is converted into a practicable form (instruction) according to the programming software, and written to the PLC through the communication route.

編程軟體係作為在Windows(商標登錄)上動作的軟體而廣泛販售，只要是Windows(商標登錄)動作的電腦、及編程軟體的話，使用電腦就易於進行從PLC之控制程式的讀出、對PLC之控制程式的寫入。 The programming software system is widely sold as a software that operates on Windows (trademark registration). As long as it is a Windows (trademark registration) operation computer and programming software, it is easy to read from the PLC control program using a computer. Write of the control program of the PLC.

為此，近年來發生了所謂從在工場已有操作結果的PLC取走控制程式、或是在將控制程式從編程軟體寫入到PLC時，竊取通訊路線流通的資料之現象。 For this reason, in recent years, there has been a phenomenon in which a control program is taken from a PLC having an operation result at a factory, or when a control program is written from a programming software to a PLC, data that is circulated in a communication route is stolen.

根據此等行為，發生了所謂非正當援用控制程式而製造 PLC的仿製品之問題。 According to these actions, a so-called improper use control program was created. The problem of the imitation of PLC.

就一般性之程式的仿製品對策手法而言，有利用難讀化之程式保護。 In the case of generic program countermeasures, it is protected by a program that is difficult to read.

根據程式的難讀化而使解讀成本增加，即使程式被竊取，對於攻擊者也難以得到有用的資訊。 According to the difficulty of reading the program, the cost of interpretation increases, and even if the program is stolen, it is difficult for an attacker to obtain useful information.

作為具體例，在專利文獻1中藉由在程式實行時將程式本身改寫而使動作複雜化，而使程式難讀化，並增加解讀成本。 As a specific example, in Patent Document 1, the operation is complicated by rewriting the program itself when the program is executed, and the program is difficult to read, and the interpretation cost is increased.

又，在專利文獻2、專利文獻3中，將程式內的資料編碼而進行難讀化，並藉由在程式實行中時解除編碼而使程式正常實行。 Further, in Patent Document 2 and Patent Document 3, the data in the program is encoded and hard-to-read, and the program is normally executed by releasing the code when the program is being executed.

【先前技術文獻】 [Previous Technical Literature] 【專利文獻】 [Patent Literature]

專利文獻1：日本特開2011-1170836號公報 Patent Document 1: Japanese Laid-Open Patent Publication No. 2011-1170836

專利文獻2：日本特開2007-298847號公報 Patent Document 2: Japanese Laid-Open Patent Publication No. 2007-298847

專利文獻3：日本特開2005-049925號公報 Patent Document 3: Japanese Laid-Open Patent Publication No. 2005-049925

但是，在對於控制程式施行難讀化時必須有FA系統特有的要件。 However, there must be an element specific to the FA system when it is difficult to read the control program.

作為對於控制程式的難讀化之FA系統特有的要件，舉例如下： As an essential element of the FA system that is difficult to read for the control program, examples are as follows:

(1)控制程式要有利用階梯式語言等FA系統特有的語言被記述之可能性 (1) The possibility that the control program is described in a language unique to the FA system such as a step language

(2)因為從PLC讀出、編輯控制程式，因此可以將難讀化 的控制程式回復到難讀化前的控制程式 (2) It is difficult to read because the control program is read and edited from the PLC. Control program reverts to the control program before reading

(3)實行時不會減低實行速度 (3) Implementation speed will not be reduced

因為控制程式之處理的實行時點為非常重要，因此幾乎不允許實行速度減低。 Since the timing of the execution of the control program is very important, speed reduction is hardly allowed.

(4)不會變更實行時的動作 (4) Will not change the action at the time of implementation

有根據動作的變更而造成處理的實行時點偏移之可能性。 There is a possibility that the processing will be shifted according to the change of the action.

在專利文獻1中，藉由在程式實行時使程式進行自身改寫，而將控制複雜化，進行難讀化。 In Patent Document 1, the program is rewritten by the program itself when the program is executed, and the control is complicated and difficult to read.

又，在專利文獻2、專利文獻3中，將程式內的資料編碼而進行難讀化，並藉由在程式實行中時解除編碼而使程式正常實行。 Further, in Patent Document 2 and Patent Document 3, the data in the program is encoded and hard-to-read, and the program is normally executed by releasing the code when the program is being executed.

因為此等難讀化手法會增加難讀化對象的動作，而造成實行速度的減低。 Because these difficult-to-read techniques increase the movement of difficult-to-read objects, the speed of implementation is reduced.

因此，此等難讀化手法對於控制程式的適用係非常困難的。 Therefore, these difficult-to-read methods are very difficult to apply to the control program.

本發明係為有鑑於上述者，以進行對於控制程式之效果性的難讀化，而使控制程式的解讀成本增加，使非正當援用變得困難為主要目的。 The present invention has been made in view of the above, and it is mainly for the purpose of making it difficult to read the effect of the control program, increasing the cost of reading the control program, and making the improper use difficult.

關於本發明之控制程式管理裝置，其係為管理記述有裝置的辨識碼即裝置辨識碼的控制程式之控制程式管理裝置，其特徵在於包括：使用固有在實行前述控制程式的控制裝置之數值即控制器固有值，產生虛擬隨機數之虛擬隨機數產生部； 使用利用前述虛擬隨機數產生部產生的虛擬隨機數，將前述控制程式所記述的裝置辨識碼置換為其他的裝置辨識碼之裝置辨識碼置換部；及 將利用前述裝置辨識碼置換部置換裝置辨識碼後的控制程式輸出到前述控制裝置之輸出部。 The control program management device according to the present invention is a control program management device that manages a control program for describing a device identification code, which is an identification code of the device, and includes a value of a control device that is inherent to the control program. a controller-specific value, generating a virtual random number generating portion of the virtual random number; a device identification code replacing unit that replaces the device identification code described in the control program with another device identification code by using a virtual random number generated by the virtual random number generating unit; and The control program after the device identification code replacement unit replacement device identification code is output to the output unit of the control device.

根據本發明，由於使用根據控制器固有值之虛擬隨機數，將控制程式內的裝置辨識碼置換為其他的裝置辨識碼，因此在控制裝置以外的裝置中無法從置換後的裝置辨識碼回復到置換前的裝置辨識碼。 According to the present invention, since the device identification code in the control program is replaced with another device identification code by using a virtual random number according to the inherent value of the controller, it is not possible to reply from the replaced device identification code to the device other than the control device. Device identification code before replacement.

為此，可以將控制程式難讀化，使控制程式的非正當援用變得困難。 For this reason, the control program can be difficult to read, making it difficult to improperly invoke the control program.

又，根據本發明，由於只置換裝置辨識碼，因此不會使從置換後的裝置辨識碼回復到置換前的裝置辨識碼後之控制程式實行時的實行速度減低，又也不會變更實行時的動作。 Moreover, according to the present invention, since only the device identification code is replaced, the execution speed when the control program after the replacement device identification code is returned to the device identification code before the replacement is not reduced, and the execution time is not changed.

又，控制裝置102及生產機器104係利用通訊線路106予以連接。 Further, the control device 102 and the production device 104 are connected by a communication line 106.

作為通訊線路105、106的具體例，可以舉例如USB(Universal Serial Bus；通用序列匯流排)纜線、或是與Ethernet(商標登錄)對應之LAN(Local Area Network；區域網路)纜線等。 Specific examples of the communication lines 105 and 106 include, for example, a USB (Universal Serial Bus) cable or a LAN (Local Area Network) cable corresponding to Ethernet (trademark registration). .

在圖1中，雖然生產機器104只圖示1台，但是 對於控制裝置102可以連接多台的生產機器104。 In Fig. 1, although the production machine 104 is only shown in one figure, A plurality of production machines 104 can be connected to the control device 102.

生產機器104係例如是伺服放大器、變換器等。 The production machine 104 is, for example, a servo amplifier, a converter, or the like.

又，FA系統係利用控制裝置102及生產機器104加以構成。 Further, the FA system is configured by the control device 102 and the production device 104.

電腦裝置101係產生利用控制裝置102實行的控制程式，又，進行已產生的控制程式的難讀化，將難讀化後的控制程式輸出到控制裝置102。 The computer device 101 generates a control program executed by the control device 102, and performs hard-to-read control of the generated control program, and outputs the hard-to-read control program to the control device 102.

電腦裝置101係相當於控制程式管理裝置的例示。 The computer device 101 corresponds to an example of a control program management device.

在電腦裝置101產生的控制程式中係記述有裝置的辨識碼即裝置辨識碼。 In the control program generated by the computer device 101, the device identification code, which is the identification code of the device, is described.

裝置辨識碼係為裝置的類別值(X、Y、M等)及裝置編號(0、1、2等)的組合。 The device identification code is a combination of the class value (X, Y, M, etc.) of the device and the device number (0, 1, 2, etc.).

所謂裝置，其係為控制裝置102中之用於控制的變數。 The so-called device is a variable for control in the control device 102.

X裝置為用以從控制裝置102的外部輸入開關等輸入訊號的變數。 The X device is a variable for inputting a signal such as a switch from the outside of the control device 102.

Y裝置為用以將訊號輸出到控制裝置102外部的變數。 The Y device is a variable for outputting a signal to the outside of the control device 102.

電腦裝置101係藉由轉換包含裝置辨識碼的數值(裝置編號)，置換裝置辨識碼，將控制程式難讀化。 The computer device 101 replaces the device identification code by converting the value (device number) including the device identification code, and makes the control program difficult to read.

在圖14的例示中，例如將控制程式131的裝置X0置換為 裝置X6，而構成難讀化控制程式132。 In the example of FIG. 14, for example, the device X0 of the control program 131 is replaced with Device X6 forms a hard-to-read control program 132.

控制裝置102係實行控制程式而控制生產機器104的動作。 The control device 102 controls the operation of the production machine 104 by executing a control program.

控制裝置102係從電腦裝置101輸入難讀化的控制程式，並解除已輸入之難讀化後控制程式的難讀化，取得難讀化前的控制程式。 The control device 102 inputs a hard-to-read control program from the computer device 101, releases the hard-to-read control program that has been input after the hard-to-read, and obtains a control program before the hard-to-read.

控制裝置102係利用理論性上與電腦裝置101之裝置辨識碼的置換順序相反的順序，將置換後的裝置辨識碼回復到置換前的裝置辨識碼而解除難讀化。 The control device 102 restores the hard-to-read decoding by reverting the replaced device identification code to the device identification code before the replacement, in the reverse order of the order of replacement of the device identification code of the computer device 101.

再者，控制裝置102係實行已解除難讀化的控制程式而控制生產機器104的動作。 Furthermore, the control device 102 controls the operation of the production device 104 by executing a control program that has been unreadable.

最後，在圖9顯示上述(3)之處理，換言之使控制程式管理部103從控制裝置102讀出難讀化控制程式132，並解除難讀化控制程式132的難讀化而復原控制程式131之處理的流程。 Finally, the processing of the above (3) is displayed in FIG. 9, in other words, the control program management unit 103 reads the hard-to-read control program 132 from the control device 102, and releases the hard-to-read control program 132 to restore the control program 131. The process of processing.

利用圖9的處理階段701，在電腦裝置101中，難讀化處理部115係透過控制程式管理部112、通訊處理部116及通訊裝置107，對於控制裝置102傳送難讀化控制程式132的讀出要求731。 In the processing unit 701 of FIG. 9, in the computer device 101, the hard-to-read processing unit 115 transmits the hard-to-read control program 132 to the control device 102 via the control program management unit 112, the communication processing unit 116, and the communication device 107. Request 731.

在控制裝置102中，當接收到讀出要求731時，通訊控制部121係傳送控制程式記憶部124內的難讀化控制程式132、及機器ID管理部122內的機器ID134。 When the control device 102 receives the read request 731, the communication control unit 121 transmits the hard-to-read control program 132 in the control program storage unit 124 and the device ID 134 in the device ID management unit 122.

在電腦裝置101中，通訊處理部116係接收難讀化控制程式132及機器ID134。 In the computer device 101, the communication processing unit 116 receives the hard-to-read control program 132 and the device ID 134.

利用處理階段702，難讀化解除處理部125係解除從控制裝置102接收的難讀化控制程式132之難讀化，作成控 制程式131。 In the processing stage 702, the hard-to-read release processing unit 125 releases the hard-to-read control of the hard-to-read control program 132 received from the control device 102, and performs control. Program 131.

難讀化控制程式132的難讀化解除係使用從控制裝置102接收的機器ID134及附加資訊133。 The hard-to-read release of the hard-to-read control program 132 uses the device ID 134 and the additional information 133 received from the control device 102.

其後，利用處理階段703，控制程式131係被儲存在控制程式記憶部114。 Thereafter, the control program 131 is stored in the control program storage unit 114 by the processing stage 703.

在圖10顯示處理階段504之控制程式難讀化處理511的流程。 The flow of the control program refractory processing 511 of the processing stage 504 is shown in FIG.

首先，利用處理階段801，為了使資料處理部303作成轉換表307，對於控制裝置102要求機器ID134。 First, in the processing stage 801, in order to cause the material processing unit 303 to create the conversion table 307, the device ID 134 is requested from the control device 102.

接著，利用處理階段802，資料處理部303係從控制裝置102收到機器ID134。 Next, using the processing stage 802, the material processing unit 303 receives the machine ID 134 from the control device 102.

之後，利用處理階段803，資料處理部303係取得現在時刻的時戳，而成為附加資訊133。 Thereafter, in the processing stage 803, the data processing unit 303 acquires the time stamp of the current time and becomes the additional information 133.

又，附加資訊133係不一定是時戳，只要是每次作成時都是不同值之資訊的話，任何資訊皆可。 Moreover, the additional information 133 is not necessarily a time stamp, and any information may be used as long as it is information of different values each time it is created.

其次，利用處理階段804，轉換表作成處理部302係實行轉換表作成處理811，作成轉換表307。 Next, in the processing stage 804, the conversion table creation processing unit 302 executes the conversion table creation processing 811 to create the conversion table 307.

最後，利用處理階段805，控制程式轉換處理部301係實行控制程式轉換處理812。 Finally, in the processing stage 805, the control program conversion processing unit 301 executes the control program conversion processing 812.

控制程式轉換處理部301係在控制程式轉換處理812中，藉由使用轉換表307將控制程式131的裝置辨識碼隨機化而轉換為難讀化控制程式132。 The control program conversion processing unit 301 converts the device identification code of the control program 131 into a hard-to-read control program 132 by using the conversion table 307 in the control program conversion processing 812.

在圖11顯示處理階段804中之轉換表作成處理811的詳細，在圖12顯示處理階段804中之轉換表作成處理 811的實施例。 The details of the conversion table creation processing 811 in the processing stage 804 are shown in FIG. 11, and the conversion table creation processing in the processing stage 804 is shown in FIG. An embodiment of 811.

首先，利用處理階段901，轉換表作成處理部302係將在控制程式131內所使用的裝置編號作為索引予以使用，並作成轉換前數值與轉換後數值的配列為相同之表911(圖12)。 First, in the processing stage 901, the conversion table creation processing unit 302 uses the device number used in the control program 131 as an index, and creates a table 911 in which the value before conversion and the converted value are the same (FIG. 12). .

之後，利用處理階段902，轉換表作成處理部302係將機器ID134及附加資訊133作為種子資料而作成虛擬隨機數912。 Thereafter, in the processing stage 902, the conversion table creation processing unit 302 creates the virtual random number 912 by using the device ID 134 and the additional information 133 as seed data.

最後，利用處理階段903，轉換表作成處理部302係使用已作成的虛擬隨機數912，並藉由將表911之轉換後的配列隨機排列，使表911之轉換後配列內的數值順序有所變化，使用數值順序有所變化之新的配列作成轉換表307。 Finally, in the processing stage 903, the conversion table creation processing unit 302 uses the created virtual random number 912, and by randomly arranging the converted columns of the table 911, the numerical order in the converted column of the table 911 is sequentially The change is made into a conversion table 307 using a new arrangement in which the numerical order is changed.

如圖12所示，轉換表307之轉換前的配列係維持表911之轉換前的配列。 As shown in FIG. 12, the arrangement before the conversion of the conversion table 307 maintains the arrangement before the conversion of the table 911.

因為轉換表307之轉換後的配列係從表911之轉換後的配列將數值順序有所變化，因此與轉換表307之轉換前的配列，使數值配列為不同。 Since the conversion order of the conversion table 307 changes the numerical order from the arrangement after the conversion of the table 911, the arrangement before the conversion of the conversion table 307 makes the numerical values different.

又，轉換表307之轉換前的配列係相當於第1配列的例示，轉換後的配列相當於第2配列的例示。 Further, the arrangement before conversion of the conversion table 307 corresponds to an example of the first arrangement, and the arrangement after conversion corresponds to an example of the second arrangement.

藉由利用前述的方式產生轉換表307，可以將轉換後的裝置編號範圍與在轉換前的控制程式131所使用之裝置編號範圍一致。 By generating the conversion table 307 in the manner described above, it is possible to match the converted device number range with the device number range used by the control program 131 before conversion.

為此，可以將轉換後的難讀化控制程式132作為控制程式而成為適當者。 For this reason, the converted hard-to-read control program 132 can be used as a control program.

又，在作成轉換表307時，在處理階段901中作為表911作成時的索引使用的數值不只是實際上在控制程式131內使用的數值，也可以使用可作為裝置編號予以使用的全部數值。 Further, when the conversion table 307 is created, the numerical value used as the index at the time of creation of the table 911 in the processing stage 901 is not limited to the numerical value actually used in the control program 131, and all numerical values usable as the device number may be used.

在圖14的控制程式131中，雖然作為裝置編號予以使用之數值是「0、2、5、7」，但是如圖12所示，作為轉換前的數值，也可以使用包含不被用來作為裝置編號的數值之[0、1、2、3、4、5、6、7]。 In the control program 131 of Fig. 14, the numerical values used as the device numbers are "0, 2, 5, and 7". However, as shown in Fig. 12, the values before the conversion may be used instead of being used. [0, 1, 2, 3, 4, 5, 6, 7] of the value of the device number.

其次，在圖13顯示處理階段805中之控制程式轉換處理812的詳細，在圖14顯示處理階段805之控制程式轉換處理812的實施例。 Next, the details of the control program conversion process 812 in the processing stage 805 are shown in FIG. 13, and the embodiment of the control program conversion process 812 in the processing stage 805 is shown in FIG.

控制程式轉換處理部301係使用轉換表307，將控制程式131的裝置辨識碼(例如X0或Y0)轉換為不同的裝置辨識碼。 The control program conversion processing unit 301 converts the device identification code (for example, X0 or Y0) of the control program 131 into a different device identification code using the conversion table 307.

具體而言，首先，利用處理階段1101，控制程式轉換處理部301係讀出一個裝置辨識碼。 Specifically, first, in the processing stage 1101, the control program conversion processing unit 301 reads out one device identification code.

再者，利用處理階段1102，控制程式轉換處理部301係參照轉換表，轉換利用處理階段1101讀出的裝置辨識碼。 Further, in the processing stage 1102, the control program conversion processing unit 301 refers to the conversion table and converts the device identification code read by the processing step 1101.

具體而言，控制程式轉換處理部301係判定裝置編號的數值之轉換前配列內的位置，並抽出位於與已判定的位置相同之轉換後配列內的數值，將裝置編號的數值轉換為已抽出之轉換後配列內的數值，進行裝置辨識碼的置換。 Specifically, the control program conversion processing unit 301 determines the position in the pre-conversion arrangement of the value of the device number, extracts the value in the post-conversion arrangement that is the same as the determined position, and converts the value of the device number to the extracted value. After the conversion, the values in the column are arranged to replace the device identification code.

利用處理階段1103，若有未轉換的裝置辨識碼，則回到處理階段1101的處理。 With the processing stage 1103, if there is an unconverted device identification code, the processing returns to the processing stage 1101.

對於所有的裝置辨識碼，反覆以上的處理直至結束。 For all device identification codes, the above processing is repeated until the end.

在圖14的例示中，控制程式131內之裝置1201的辨識碼「X0」的情況下，因為與轉換表307的數值「0」對應的轉換後數值為「6」，因此控制程式轉換處理部301係將「X0」置換為「X6」。 In the example of FIG. 14, when the identification code "X0" of the device 1201 in the program 131 is controlled, since the converted value corresponding to the value "0" of the conversion table 307 is "6", the control program conversion processing unit is controlled. The 301 system replaces "X0" with "X6".

又，在從控制程式131到難讀化控制程式132的轉換結束後，銷毀轉換表307亦可。 Further, after the conversion from the control program 131 to the hard-to-read control program 132 is completed, the conversion table 307 may be destroyed.

又，因為附加資訊133係被用於控制裝置102之逆轉換表404的產生，直至逆轉換表404產生前，在電腦裝置101中必須儲存有附加資訊133。 Further, since the additional information 133 is used for generation of the inverse conversion table 404 of the control device 102, the additional information 133 must be stored in the computer device 101 until the inverse conversion table 404 is generated.

但是，在逆轉換表404產生後，電腦裝置101銷毀附加資訊133亦可。 However, after the inverse conversion table 404 is generated, the computer device 101 may destroy the additional information 133.

其次，在圖15顯示控制裝置102之難讀化解除處理611的詳細。 Next, the details of the hard-to-read release processing 611 of the control device 102 are shown in FIG.

首先，利用處理階段1301，資料處理部403係從機器ID管理部122讀出機器ID134。 First, in the processing stage 1301, the material processing unit 403 reads the device ID 134 from the device ID management unit 122.

其次，利用處理階段1302，資料處理部403係從附加資訊管理部123讀出附加資訊133。 Next, in the processing stage 1302, the material processing unit 403 reads the additional information 133 from the additional information management unit 123.

之後，利用處理階段1303，逆轉換表作成處理部402係實行逆轉換表作成處理1311，作成逆轉換表404。 Thereafter, in the processing stage 1303, the inverse conversion table creation processing unit 402 executes the inverse conversion table creation processing 1311 to create the inverse conversion table 404.

之後，利用處理階段1304，控制程式逆轉換處理部401係實行控制程式逆轉換處理1312，使用逆轉換表404而將難讀化控制程式132轉換為控制程式131。 Thereafter, in the processing stage 1304, the control program inverse conversion processing unit 401 executes the control program inverse conversion processing 1312, and converts the hard-to-read control program 132 into the control program 131 using the inverse conversion table 404.

在圖16顯示逆轉換表作成處理1311的詳細，在圖17顯示逆轉換表作成處理1311的實施例。 The detail of the inverse conversion table creation processing 1311 is shown in Fig. 16, and the reverse conversion table creation processing 1311 is shown in Fig. 17 as an embodiment.

首先，利用處理階段1401，逆轉換表作成處理部402係使用難讀化控制程式132內所使用之裝置編號，作成轉換前的數值與轉換後的數值相同之表1411(圖17)。 First, in the processing stage 1401, the inverse conversion table creation processing unit 402 uses the device number used in the hard-to-read control program 132 to create a table 1411 (FIG. 17) in which the value before conversion is the same as the converted value.

之後，利用處理階段1402，逆轉換表作成處理部402係將機器ID134及附加資訊133作為種子資料而作成虛擬隨機數1412。 Thereafter, in the processing stage 1402, the inverse conversion table creation processing unit 402 creates the virtual random number 1412 by using the device ID 134 and the additional information 133 as seed data.

又，電腦裝置101之轉換表作成處理部302中的虛擬隨機數之產生演算法、及控制裝置102之逆轉換表作成處理部402中的虛擬隨機數之產生演算法為相同。 Further, the generation algorithm of the virtual random number in the conversion table creation processing unit 302 of the computer device 101 and the generation algorithm of the virtual random number in the inverse conversion table creation processing unit 402 of the control device 102 are the same.

換言之，逆轉換表作成處理部402係產生與利用轉換表作成處理部302產生的虛擬隨機數相同的虛擬隨機數。 In other words, the inverse conversion table creation processing unit 402 generates the same virtual random number as the virtual random number generated by the conversion table creation processing unit 302.

利用處理階段1403，逆轉換表作成處理部402係使用已作成之虛擬隨機數1412，藉由將表1411之轉換前配列內的數值隨機排列，而使表1411之轉換前配列內的數值有所變化，使用數值順序有所變化的新配列而作成逆轉換表404。 In the processing stage 1403, the inverse conversion table creation processing unit 402 uses the created virtual random number 1412, and by randomly arranging the values in the pre-conversion arrangement of the table 1411, the values in the pre-conversion column of the table 1411 are made. The change is made into an inverse conversion table 404 using a new arrangement in which the numerical order is changed.

如圖17所示，逆轉換表404之轉換後的配列係維持表1411之轉換後的配列。 As shown in FIG. 17, the converted arrangement of the inverse conversion table 404 maintains the converted arrangement of the table 1411.

因為逆轉換表404之轉換前的配列係從表1411之轉換前的配列使數值順序有所變化，因此與逆轉換表404之轉換後的配列數值順序不同。 Since the arrangement before the conversion of the inverse conversion table 404 changes the numerical order from the arrangement before the conversion of the table 1411, the order of the values after the conversion of the inverse conversion table 404 is different.

又，逆轉換表404之轉換前的配列係相當於第4配列的例示，轉換後的配列係相當於第3配列的例示。 Further, the arrangement before the conversion of the inverse conversion table 404 corresponds to the example of the fourth arrangement, and the arrangement after the conversion corresponds to the example of the third arrangement.

逆轉換表404係使用機器ID134及從難讀化處理部115傳送之附加資訊133，並使用與轉換表作成處理811相 同的演算法(理論性上相反的順序)加以作成。 The inverse conversion table 404 uses the device ID 134 and the additional information 133 transmitted from the hard-to-read processing unit 115, and uses the conversion table creation processing 811. The same algorithm (theoretically reversed order) is created.

為此，在利用控制程式難讀化處理511進行控制程式131的難讀化時所使用之轉換表307與逆轉換表404係除了轉換前的配列及轉換後的配列相反之外，其餘相同。 For this reason, the conversion table 307 and the inverse conversion table 404 used when the control program 131 is difficult to read by the control program hard-to-read processing 511 are the same except that the arrangement before conversion and the arrangement after conversion are reversed.

其次，在圖18顯示控制程式逆轉換處理1312的詳細，在圖19顯示控制程式逆轉換處理1312的實施例。 Next, the details of the control program inverse conversion processing 1312 are shown in Fig. 18, and an embodiment of the control program inverse conversion processing 1312 is shown in Fig. 19.

控制程式逆轉換處理部401係使用逆轉換表404，將被隨機化之難讀化控制程式132的裝置辨識碼轉換為原來的裝置辨識碼。 The control program inverse conversion processing unit 401 converts the device identification code of the randomized hard-to-read control program 132 into the original device identification code using the inverse conversion table 404.

具體而言，利用處理階段1601，控制程式逆轉換處理部401係讀出一個裝置辨識碼。 Specifically, in the processing stage 1601, the control program inverse conversion processing unit 401 reads out one device identification code.

接著，利用處理階段1602，控制程式逆轉換處理部401係參照逆轉換表404轉換裝置辨識碼。 Next, in the processing stage 1602, the control program inverse conversion processing unit 401 refers to the inverse conversion table 404 to convert the device identification code.

具體而言，控制程式逆轉換處理部401係判定裝置編號的數值之轉換前配列內的位置，並抽出位於與已判定的位置相同之轉換後配列內的數值，將裝置編號的數值轉換為已抽出的數值，進行裝置辨識碼的復原。 Specifically, the control program inverse conversion processing unit 401 determines the position in the pre-conversion arrangement of the value of the device number, extracts the value in the post-conversion arrangement that is the same as the determined position, and converts the value of the device number to The extracted value is used to recover the device identification code.

利用處理階段1603，若有未轉換的裝置辨識碼，則回到處理階段1601的處理。 With the processing stage 1603, if there is an unconverted device identification code, the processing returns to the processing stage 1601.

對於所有的裝置辨識碼，反覆以上的處理直至結束。 For all device identification codes, the above processing is repeated until the end.

在圖19的例示中，難讀化控制程式132內之裝置1701的辨識碼「X6」的情況下，因為與逆轉換表404的數值「6」對應的轉換後數值為「0」，因此控制程式逆轉換處理部401係將「X6」置換為「X0」。 In the example of FIG. 19, when the identification code "X6" of the device 1701 in the control program 132 is difficult to read, since the converted value corresponding to the value "6" of the inverse conversion table 404 is "0", the control is performed. The program inverse conversion processing unit 401 replaces "X6" with "X0".

其次，在圖20顯示圖9所示之難讀化解除處理711的詳細。 Next, the details of the hard-to-read release processing 711 shown in FIG. 9 are shown in FIG.

首先，利用處理階段1801，資料處理部403係從控制裝置102讀出機器ID134。 First, in the processing stage 1801, the material processing unit 403 reads the device ID 134 from the control device 102.

其次，利用處理階段1802，附加資訊認證部306係確認被儲存的附加資訊133與難讀化時作成的附加資訊133為相同者。 Next, in the processing stage 1802, the additional information authentication unit 306 confirms that the stored additional information 133 is the same as the additional information 133 created when the reading is difficult.

之後，利用處理階段1803，逆轉換表作成處理部305係實行逆轉換表作成處理1811，作成逆轉換表308。 Thereafter, in the processing stage 1803, the inverse conversion table creation processing unit 305 executes the inverse conversion table creation processing 1811 to create the inverse conversion table 308.

之後，利用處理階段1804，控制程式逆轉換處理部304係實行控制程式逆轉換處理1812，使用逆轉換表308而將難讀化控制程式132轉換為控制程式131。 Thereafter, in the processing stage 1804, the control program inverse conversion processing unit 304 executes the control program inverse conversion processing 1812, and uses the inverse conversion table 308 to convert the difficult-to-read control program 132 into the control program 131.

又，逆轉換表作成處理1811的動作係與逆轉換表作成處理1311相同，控制程式逆轉換處理1812的動作係與控制程式逆轉換處理1312相同。 Further, the operation of the inverse conversion table creation processing 1811 is the same as the inverse conversion table creation processing 1311, and the operation of the control program inverse conversion processing 1812 is the same as the control program inverse conversion processing 1312.

為此，省略逆轉換表作成處理1811及控制程式逆轉換處理1812的說明。 For this reason, the description of the inverse conversion table creation processing 1811 and the control program inverse conversion processing 1812 is omitted.

根據以上所示之本實施形態，可以得到以下的效果。 According to the embodiment described above, the following effects can be obtained.

(1)因為控制程式與裝置之輸入/出的關係對於解讀控制程式為非常重要，因此藉由裝置編號的置換，使控制程式的解讀變得困難。 (1) Since the relationship between the control program and the input/output of the device is very important for the interpretation control program, the interpretation of the control program becomes difficult by the replacement of the device number.

(2)以利用控制裝置解除難讀化控制程式的難讀化後再實行控制程式的方式，可以進行從難讀化控制程式到原本的控制 程式之逆轉換。 (2) It is possible to perform the control from the hard-to-read control program to the original control by releasing the hard-to-read control program from the control device and then executing the control program. Inverse conversion of the program.

(3)因為在控制程式實行前才解除難讀化，因此不會使控制程式的實行速度減低，動作也不會有所變化。 (3) Since the hard-to-read is released before the control program is executed, the execution speed of the control program is not reduced, and the operation does not change.

(4)因為轉換後的裝置編號係為利用控制裝置可控制的裝置編號，因此難讀化後的控制程式係可以利用控制裝置實行。 (4) Since the device number after the conversion is a device number controllable by the control device, the control program that is difficult to read can be implemented by the control device.

但是，在利用機器ID不同的控制裝置、或者正式的控制裝置(具有解除難讀化機能的控制裝置)以外的機器實行控制程式的情況下，因為無法使控制程式正常動作，因此使根據不正當援用之仿製品的製造變得困難。 However, when a control program is executed by a device other than a control device having a different device ID or a control device having a normal control device (a control device having a function of releasing the hard-to-read function), the control program cannot be operated normally, and therefore the fraudulent operation is performed. The manufacture of the imitation products that have been used has become difficult.

(5)在作成轉換表時，藉由在索引使用可作為裝置編號予以使用的所有數值，因為使裝置編號轉換後的裝置編號之數值範圍變大，而使難讀化方式的解讀變得更困難。 (5) When creating a conversion table, by using all the values that can be used as the device number in the index, the interpretation of the hard-to-read method becomes more complicated by increasing the numerical range of the device number after the device number conversion. difficult.

(6)藉由在附加資訊使用時戳等每次作成都不同的資訊，使轉換表具有隨機性，即使在與相同的控制裝置對應將相同的控制程式難讀化時，因為可以得到不同的難讀化結果，使難讀化的解讀變得困難。 (6) By using different information such as time stamps for additional information, the conversion table is random, even if the same control program is difficult to read in correspondence with the same control device, because different Difficult to read the results, making the interpretation of difficult to read becomes difficult.

以上，在本實施形態中，說明包括以下手段之控制系統。 As described above, in the present embodiment, a control system including the following means will be described.

(1)使用從機器ID作成的虛擬隨機數，作成將某個數值轉換為不同的數值之轉換表的手段 (1) Using a virtual random number created from a machine ID to create a conversion table that converts a certain value into a different value

(2)使用上述(1)的轉換表，轉換控制程式之裝置編號的手段 (2) means for converting the device number of the control program using the conversion table of (1) above

(3)將上述(2)之轉換後的控制程式傳送到控制器的手段 (3) means for transmitting the converted control program of (2) above to the controller

(4)將轉換後的控制程式進行逆轉換的手段 (4) means for inverse conversion of the converted control program

在圖24顯示本實施形態之轉換表作成處理811的詳細。 The details of the conversion table creation processing 811 of this embodiment are shown in FIG.

首先，利用處理階段2201，轉換表作成處理部1902係將作成的轉換表1907之個數設定在表設定資訊1909。 First, in the processing stage 2201, the conversion table creation processing unit 1902 sets the number of created conversion tables 1907 in the table setting information 1909.

其次，利用處理階段2202，轉換表作成處理部1902係將控制程式131內所使用的裝置編號用來作為索引，作成轉換前的配列與轉換後的配列相同之表2211。 Next, in the processing stage 2202, the conversion table creation processing unit 1902 uses the device number used in the control program 131 as an index, and creates a table 2211 in which the arrangement before conversion and the arrangement after conversion are the same.

該處理係與圖11之處理階段901的處理相同。 This processing is the same as the processing of the processing stage 901 of FIG.

利用處理階段2203，轉換表作成處理部1902係將機器ID134及附加資訊133作為種子資料作成虛擬隨機數2212。 In the processing stage 2203, the conversion table creation processing unit 1902 creates the virtual random number 2212 by using the device ID 134 and the additional information 133 as seed data.

該處理係與圖11之處理階段902的處理相同。 This processing is the same as the processing of processing stage 902 of FIG.

利用處理階段2204，轉換表作成處理部1902係使用已作成的虛擬隨機數2212，將表2211之轉換後的配列隨機排列，而使表2211之轉換後配列內的數值順序有所變化，使用數值順序有所變化之新配列作成轉換表1907。 In the processing stage 2204, the conversion table creation processing unit 1902 uses the created virtual random number 2212 to randomly arrange the converted lists of the table 2211, and changes the numerical order in the converted list of the table 2211, and uses the numerical values. A new arrangement with a change in order is made into a conversion table 1907.

該處理係與圖11之處理階段903的處理相同。 This processing is the same as the processing of the processing stage 903 of FIG.

又，已作成的轉換表1907係與計數值對應。 Further, the created conversion table 1907 corresponds to the count value.

例如，在處理階段2201設定的數量為「2」的情況下，轉換表1907係作成2個。 For example, when the number set in the processing stage 2201 is "2", the conversion table 1907 is created as two.

接著，第1個轉換表1907A係與計數值「0」對應，第2個轉換表1907B係與計數值「1」對應。 Next, the first conversion table 1907A corresponds to the count value "0", and the second conversion table 1907B corresponds to the count value "1".

接著，利用處理階段2205，若是表的作成數未達利用處理階段2201所設定的數量，則回到處理階段2202。 Next, in the processing stage 2205, if the number of creations of the table does not reach the number set by the processing stage 2201, the processing returns to the processing stage 2202.

又，利用處理階段2205，若是表的作成數已達到利用處理階段2201所設定的數量則結束處理。 Further, in the processing stage 2205, if the number of creations of the table has reached the number set by the processing stage 2201, the processing is terminated.

首先，利用處理階段2301，控制程式轉換處理部1901係讀出一個裝置辨識碼。 First, in the processing stage 2301, the control program conversion processing unit 1901 reads out one device identification code.

接著，利用處理階段2302，控制程式轉換處理部1901係確認特定計數器的計數值，並參照與現在的計數值對應的轉換表1907，轉換利用處理階段2301讀出的裝置辨識碼。 Next, in the processing stage 2302, the control program conversion processing unit 1901 checks the count value of the specific counter, and refers to the conversion table 1907 corresponding to the current count value, and converts the device identification code read by the processing stage 2301.

在設定於表設定資訊1909的數量為「2」的情況下，計數器的計數值採用「0」或「1」。 When the number of table setting information 1909 is "2", the counter value is "0" or "1".

例如，現在計數值為「0」的話，控制程式轉換處理部1901係選擇與計數值「0」對應之轉換表1907。 For example, when the count value is "0", the control program conversion processing unit 1901 selects the conversion table 1907 corresponding to the count value "0".

接著，參照已選擇之轉換表1907的轉換前配列及轉換後配列，轉換利用處理階段2301讀出的裝置辨識碼。 Next, the device identification code read by the processing stage 2301 is converted by referring to the pre-conversion arrangement and the post-conversion arrangement of the selected conversion table 1907.

使用轉換表1907之裝置編號的轉換處理本身係與利用實施形態1所示者相同。 The conversion process using the device number of the conversion table 1907 is the same as that shown in the first embodiment.

又，依據計數值而選擇的轉換表1907之轉換後的配列係相當於選擇第2配列的例示。 Further, the converted arrangement of the conversion table 1907 selected in accordance with the count value corresponds to an example in which the second arrangement is selected.

之後，利用處理階段2303，若是計數器的計數值未達到表設定資訊1909的設定數，利用處理階段2304，控制 程式轉換處理部1901係增加計數器的計數值。 Thereafter, using the processing stage 2303, if the count value of the counter does not reach the set number of the table setting information 1909, the processing stage 2304 is used to control The program conversion processing unit 1901 increases the count value of the counter.

若是計數器的計數值已達到表設定資訊1909的設定數，則利用處理階段2305將計數器的計數值初期化。 If the count value of the counter has reached the set number of the table setting information 1909, the counter value of the counter is initialized by the processing stage 2305.

利用處理階段2303，若有未轉換的裝置辨識碼，則回到處理階段2301。 With processing stage 2303, if there is an unconverted device identification code, then return to processing stage 2301.

對於所有的裝置辨識碼，反覆以上的處理直至結束。 For all device identification codes, the above processing is repeated until the end.

在圖26中，控制程式轉換處理部1901係在控制程式131內的裝置2401(X0)的轉換時，選擇轉換表1907A。 In FIG. 26, the control program conversion processing unit 1901 selects the conversion table 1907A when the device 2401 (X0) in the control program 131 is switched.

因為轉換表1907A中與數值「0」對應之轉換後的數值為「6」，因此控制程式轉換處理部1901係將「X0」轉換為「X6」。 Since the converted value corresponding to the value "0" in the conversion table 1907A is "6", the control program conversion processing unit 1901 converts "X0" to "X6".

其次，控制程式轉換處理部1901係在控制程式131內的裝置2402(Y0)的轉換時，前進計數器而選擇轉換表1907B。 Next, the control program conversion processing unit 1901 advances the counter and selects the conversion table 1907B when the device 2402 (Y0) in the control program 131 is switched.

因為轉換表1907B中與數值「0」對應之轉換後的數值為「5」，因此控制程式轉換處理部1901係將「Y0」轉換為「Y5」。 Since the converted value corresponding to the value "0" in the conversion table 1907B is "5", the control program conversion processing unit 1901 converts "Y0" to "Y5".

在圖27顯示關於本實施形態之逆轉換表作成處理1311的詳細。 The details of the inverse conversion table creation processing 1311 of this embodiment are shown in FIG.

首先，利用處理階段2501，逆轉換表作成處理部402係將表設定資訊2005的數量設定為作成的逆轉換表2004的數量。 First, in the processing stage 2501, the inverse conversion table creation processing unit 402 sets the number of table setting information 2005 to the number of created inverse conversion tables 2004.

利用處理階段2502，逆轉換表作成處理部402係使用在難讀化控制程式132內所使用的裝置編號，作成轉換前的數值與轉換後的數值相同的表2511。 In the processing stage 2502, the inverse conversion table creation processing unit 402 uses the device number used in the hard-to-read control program 132 to create a table 2511 in which the value before conversion is the same as the converted value.

之後，利用處理階段2503，逆轉換表作成處理部2002係將機器ID134及附加資訊133作為種子資料而作成虛 擬隨機數2512。 Thereafter, in the processing stage 2503, the inverse conversion table creation processing unit 2002 creates the virtual machine ID 134 and the additional information 133 as seed data. Quasi-random number 2512.

在本實施形態亦同，電腦裝置101之轉換表作成處理部1902之虛擬隨機數的產生演算法、與控制裝置102之逆轉換表作成處理部2002之虛擬隨機數的產生演算法為相同。 Also in the present embodiment, the generation algorithm of the virtual random number of the conversion table creation processing unit 1902 of the computer device 101 is the same as the generation algorithm of the virtual random number of the inverse conversion table creation processing unit 2002 of the control device 102.

換言之，逆轉換表作成處理部2002係產生與利用轉換表作成處理部1902產生的虛擬隨機數相同之虛擬隨機數。 In other words, the inverse conversion table creation processing unit 2002 generates a virtual random number identical to the virtual random number generated by the conversion table creation processing unit 1902.

利用處理階段2504，逆轉換表作成處理部2002係使用已作成的虛擬隨機數2512，並藉由將表2511之轉換前配列內的數值順序隨機排列，而使表2511之轉換前配列內的數值順序有所變化，使用數值順序有所變化新配列作成逆轉換表2004。 In the processing stage 2504, the inverse conversion table creation processing unit 2002 uses the created virtual random number 2512, and sequentially arranges the numerical values in the pre-conversion arrangement of the table 2511 in order to make the values in the table before the conversion of the table 2511. The order has changed, and the numerical order has been changed to create an inverse conversion table 2004.

與轉換表1907相同，已作成的逆轉換表2004係與計數值對應。 Like the conversion table 1907, the inverse conversion table 2004 that has been created corresponds to the count value.

例如，在處理階段2501設定的數量為「2」的情況下，逆轉換表2004係作成2個。 For example, when the number set in the processing stage 2501 is "2", the inverse conversion table 2004 is created in two.

接著，第1個逆轉換表2004A係與計數值「0」對應，第2個逆轉換表2004B係與計數值「1」對應。 Next, the first inverse conversion table 2004A corresponds to the count value "0", and the second inverse conversion table 2004B corresponds to the count value "1".

接著，利用處理階段2505，若是表的作成數未達利用處理階段2501所設定的數量，則回到處理階段2502。 Next, in the processing stage 2505, if the number of creations of the table does not reach the number set by the processing stage 2501, the processing returns to the processing stage 2502.

又，利用處理階段2505，若是表的作成數已達到利用處理階段2501所設定的數量則結束處理。 Further, in the processing stage 2505, if the number of creations of the table has reached the number set by the processing stage 2501, the processing is terminated.

首先，利用處理階段2601，控制程式逆轉換處理部2001係讀出一個裝置辨識碼。 First, in the processing stage 2601, the control program inverse conversion processing unit 2001 reads out a device identification code.

接著，利用處理階段2602，控制程式逆轉換處理部2001係參照與計數器的計數值因應的逆轉換表2004，轉換裝置辨識碼。 Next, in the processing stage 2602, the control program inverse conversion processing unit 2001 refers to the inverse conversion table 2004 corresponding to the count value of the counter, and converts the device identification code.

在設定於表設定資訊2005的數量為「2」的情況下，計數器的計數值採用「0」或「1」。 When the number of table setting information 2005 is "2", the counter value is "0" or "1".

例如，現在的計數值為「0」的話，控制程式逆轉換處理部2001係選擇與計數值「0」對應之逆轉換表2004。 For example, when the current count value is "0", the control program inverse conversion processing unit 2001 selects the inverse conversion table 2004 corresponding to the count value "0".

接著，參照已選擇之逆轉換表2004的轉換前配列及轉換後配列，轉換利用處理階段2601讀出的裝置辨識碼。 Next, the device identification code read by the processing stage 2601 is converted by referring to the pre-conversion arrangement and the post-conversion arrangement of the selected inverse conversion table 2004.

使用逆轉換表2004之裝置編號的逆轉換處理本身係與利用實施形態1所示者相同。 The inverse conversion process using the device number of the inverse conversion table 2004 is the same as that shown in the first embodiment.

又，依據計數值而選擇的逆轉換表2004之轉換前的配列係相當於選擇第4配列的例示。 Further, the arrangement before the conversion of the inverse conversion table 2004 selected based on the count value corresponds to an example in which the fourth arrangement is selected.

之後，利用處理階段2603，若是計數器的數值未達到表設定資訊2005的設定數，利用處理階段2604，控制程式逆轉換處理部2001係增加計數器的計數值。 Thereafter, in the processing stage 2603, if the value of the counter does not reach the set number of the table setting information 2005, the control program inverse conversion processing unit 2001 increases the count value of the counter by the processing stage 2604.

若是計數器的計數值已達到表設定資訊2005的設定數，控制程式逆轉換處理部2001係利用處理階段2605將計數器初期化。 If the count value of the counter has reached the set number of the table setting information 2005, the control program inverse conversion processing unit 2001 initializes the counter by the processing stage 2605.

利用處理階段2603，若有未轉換的裝置，則回到處理階段2601。 With processing stage 2603, if there is an unconverted device, it returns to processing stage 2601.

對於所有的裝置辨識碼，反覆以上的處理直至結束。 For all device identification codes, the above processing is repeated until the end.

在圖29中，控制程式逆轉換處理部2001係在難讀化控制程式132內的裝置2701(X6)的轉換時，選擇逆轉換表2004A。 In FIG. 29, the control program inverse conversion processing unit 2001 selects the inverse conversion table 2004A at the time of conversion of the device 2701 (X6) in the hard-to-read control program 132.

因為逆轉換表2004A中與數值「6」對應之轉換後的數值為「0」，因此控制程式逆轉換處理部2001係將「X6」轉換為「X0」。 Since the converted value corresponding to the value "6" in the inverse conversion table 2004A is "0", the control program inverse conversion processing unit 2001 converts "X6" to "X0".

其次，控制程式逆轉換處理部2001係在難讀化控制程式132內的裝置2702(Y5)的轉換時，前進計數器而選擇逆轉換表2004B。 Next, the control program inverse conversion processing unit 2001 advances the counter and selects the inverse conversion table 2004B at the time of conversion of the device 2702 (Y5) in the hard-to-read control program 132.

因為逆轉換表2004B中與數值「5」對應之轉換後的數值為「0」，因此控制程式逆轉換處理部2001係將「Y5」轉換為「Y0」。 Since the converted value corresponding to the value "5" in the inverse conversion table 2004B is "0", the control program inverse conversion processing unit 2001 converts "Y5" to "Y0".

在實施形態1中雖然是將控制程式內之相同的裝置編號全部轉換為相同的裝置編號，但是若是本實施形態的話則可以防止前述問題。 In the first embodiment, the same device numbers in the control program are all converted into the same device number. However, the present embodiment can prevent the above problems.

在實施形態1中控制程式轉換處理部301係使用轉換表307進行裝置編號的轉換，但是在本實施形態中並不是轉換裝置編號，而是附加步驟編號再轉換轉換表。 In the first embodiment, the control program conversion processing unit 301 converts the device number using the conversion table 307. However, in the present embodiment, instead of the conversion device number, the step number conversion conversion table is added.

關於本實施形態之控制程式131係如圖31所示，在各裝置辨識碼附註步驟編號。 As shown in FIG. 31, the control program 131 of the present embodiment has a step number in each device identification code.

在本實施形態中，根據控制程式轉換處理部301之控制程式轉換處理812與根據控制程式逆轉換處理部401之控制程式逆轉換處理1311係與實施形態1不同。 In the present embodiment, the control program conversion processing 812 of the control program conversion processing unit 301 and the control program inverse conversion processing 1311 according to the control program inverse conversion processing unit 401 are different from the first embodiment.

接著，利用處理階段2802，控制程式轉換處理部301係參照轉換表307，將讀出的裝置辨識碼轉換為該步驟的裝置辨識碼。 Next, in the processing stage 2802, the control program conversion processing unit 301 refers to the conversion table 307, and converts the read device identification code into the device identification code of this step.

更具體而言，控制程式轉換處理部301係判定附註在已讀出之裝置辨識碼之步驟編號的數值之轉換前配列內的位置。 More specifically, the control program conversion processing unit 301 determines the position in the pre-conversion arrangement in which the value of the step number of the read device identification code is added.

接著，控制程式轉換處理部301係抽出位於與判定後的位置相同位置之轉換後配列內的數值。 Next, the control program conversion processing unit 301 extracts the numerical value in the post-conversion arrangement at the same position as the determined position.

接著，控制程式轉換處理部301係選定將已抽出的數值作為步驟編號予以附註之裝置辨識碼，將利用處理階段2801讀出的裝置辨識碼置換為已選定的裝置辨識碼。 Next, the control program conversion processing unit 301 selects the device identification code to which the extracted numerical value is a step number, and replaces the device identification code read by the processing stage 2801 with the selected device identification code.

其次，利用處理階段2803，若是有未轉換的裝置辨識碼，則回到處理階段2801。 Next, using the processing stage 2803, if there is an unconverted device identification code, it returns to the processing stage 2801.

對於所有的裝置辨識碼，反覆以上的處理直至結束。 For all device identification codes, the above processing is repeated until the end.

在圖31的例示中，裝置2901(X0)的步驟編號為「0」。 In the example of FIG. 31, the step number of the device 2901 (X0) is "0".

與轉換表307之數值「0」對應的轉換後數值為「6」。 The converted value corresponding to the value "0" of the conversion table 307 is "6".

為此，控制程式轉換處理部301係將「X0」轉換為附註有步驟編號「6」的裝置辨識碼之「Y7」。 Therefore, the control program conversion processing unit 301 converts "X0" into "Y7" of the device identification code having the step number "6".

其次，在圖32顯示控制程式逆轉換處理1312的詳細，在圖33顯示控制程式逆轉換處理1312的實施例。 Next, the details of the control program inverse conversion processing 1312 are shown in Fig. 32, and an embodiment of the control program inverse conversion processing 1312 is shown in Fig. 33.

首先，利用處理階段3001，控制程式逆轉換處理部401係讀出一個裝置辨識碼。 First, in the processing stage 3001, the control program inverse conversion processing unit 401 reads out one device identification code.

接著，利用處理階段3002，控制程式逆轉換處理部401係參照逆轉換表404將已讀出的裝置辨識碼轉換為該步驟的裝置辨識碼。 Next, in the processing stage 3002, the control program inverse conversion processing unit 401 refers to the inverse conversion table 404 to convert the read device identification code into the device identification code of this step.

更具體而言，控制程式逆轉換處理部401係判定附註在已讀出的裝置辨識碼之步驟編號的數值之轉換前配列內的位置。 More specifically, the control program inverse conversion processing unit 401 determines the position in the pre-conversion arrangement in which the value of the step number of the read device identification code is added.

接著，控制程式逆轉換處理部401係抽出位於與判定後之轉換前配列內的位置相同位置之轉換後配列內的數值。 Next, the control program inverse conversion processing unit 401 extracts the numerical value in the post-conversion arrangement located at the same position as the position in the pre-conversion arrangement after the determination.

接著，控制程式逆轉換處理部401係選定將已抽出的數值作為步驟編號予以附註之裝置辨識碼，將利用處理階段3001讀出的裝置辨識碼置換為已選定的裝置辨識碼。 Next, the control program inverse conversion processing unit 401 selects the device identification code to which the extracted numerical value is a step number, and replaces the device identification code read by the processing stage 3001 with the selected device identification code.

其次，利用處理階段3003，若是有未轉換的裝置辨識碼，則回到處理階段3001。 Next, using the processing stage 3003, if there is an unconverted device identification code, it returns to the processing stage 3001.

對於所有的裝置辨識碼，反覆以上的處理直至結束。 For all device identification codes, the above processing is repeated until the end.

在圖33的例示中，裝置3101(Y7)的步驟編號為「0」。 In the example of Fig. 33, the step number of the device 3101 (Y7) is "0".

與逆轉換表404之數值「0」對應之轉換後的數值為「6」。 The converted value corresponding to the value "0" of the inverse conversion table 404 is "6".

為此，控制程式逆轉換處理部401係將「Y7」轉換為附註有步驟編號「6」的裝置辨識碼之「X0」。 Therefore, the control program inverse conversion processing unit 401 converts "Y7" into "X0" of the device identification code having the step number "6".

在本實施形態中，因為不只是裝置編號，連同裝置種類也可以進行隨機化，因此認為難讀化控制程式的解讀變得困難。 In the present embodiment, since the device number can be randomized regardless of the device number, it is considered that the interpretation of the difficult-to-read control program becomes difficult.

又，在本實施形態中，包含在轉換表307及逆轉換表404之數值「0~7」係依據控制程式131內的步驟編號「0~7」。 Further, in the present embodiment, the numerical values "0 to 7" included in the conversion table 307 and the inverse conversion table 404 are based on the step numbers "0 to 7" in the control program 131.

換言之，在使用步驟編號轉換裝置辨識碼的情況下，必須使用步驟編號的數值產生轉換表307。 In other words, in the case of using the step number conversion device identification code, it is necessary to generate the conversion table 307 using the numerical value of the step number.

同樣，對於逆轉換表404也必須使用步驟編號的數值加以產生。 Similarly, the inverse conversion table 404 must also be generated using the value of the step number.

又，將實施形態2及實施形態3組合後加以實施亦可。 Further, the second embodiment and the third embodiment may be combined and implemented.

換言之，電腦裝置101之難讀化處理部115係如實施形態 2所示，產生多個轉換表，並因應計數值選擇多個轉換表。 In other words, the hard-to-read processing unit 115 of the computer device 101 is as an embodiment. As shown in 2, a plurality of conversion tables are generated, and a plurality of conversion tables are selected in accordance with the count value.

又，難讀化處理部115係如實施形態3所示，使其介有步驟編號，並使用已選擇的轉換表轉換裝置辨識碼。 Further, the hard-to-read processing unit 115 is provided with the step number as shown in the third embodiment, and uses the selected conversion table conversion device identification code.

又，控制裝置102的難讀化解除處理部125係如實施形態2所示，產生多個逆轉換表，並因應計數值選擇多個逆轉換表。 Further, as shown in the second embodiment, the hard-to-read release processing unit 125 of the control device 102 generates a plurality of inverse conversion tables, and selects a plurality of inverse conversion tables in accordance with the count value.

又，難讀化解除處理部125係如實施形態3所示，使其介有步驟編號，並使用已選擇的逆轉換表復原裝置辨識碼。 Further, as shown in the third embodiment, the hard-to-read release processing unit 125 interpolates the device identification code using the selected inverse conversion table as shown in the third embodiment.

在本實施形態中，說明了包括：使用轉換表，並與控制程式的步驟數因應而轉換裝置辨識碼的手段之控制系統。 In the present embodiment, a control system including means for converting a device identification code using a conversion table and responding to the number of steps of the control program has been described.

如以上所示，藉由使用實施形態1~3所示之手法，可以進行控制程式的非正當援用或在控制器寫入時之在通訊線路的盜取之對策。 As described above, by using the methods shown in the first to third embodiments, it is possible to perform an unauthorized use of the control program or a countermeasure against theft of the communication line when the controller writes.

在實施形態1~3所示之手法中，在利用控制裝置實行控制程式前，因為進行難讀化的解除不會引起實行速度的減低，實行時的動作也不會有所變化。 In the methods shown in the first to third embodiments, before the control program is executed by the control device, the release of the hard-to-read is not caused by the decrease in the execution speed, and the operation at the time of the execution does not change.

又，若是使用逆轉換表可以將難讀化控制程式逆轉換為難讀化前的控制程式。 Moreover, if the inverse conversion table is used, the hard-to-read control program can be inversely converted into a control program before the hard-to-read.

再者，在難讀化之解除時，藉由讀出使用硬體固有值即機器ID，因此即使將難讀化控制程式及難讀化解除所必要的附加資訊複製到其他控制裝置，控制程式也不會進行預定的動作，因此使根據非正當援用之仿製品的製造變得困難。 In addition, when the hard-to-read is released, by using the machine ID which is the hardware-specific value, even if the hard-to-read control program and the additional information necessary for the hard-to-read release are copied to other control devices, the control program The predetermined action is also not performed, so that it is difficult to manufacture the imitation according to the improper use.

以上，雖然是針對本發明的實施形態進行說明，但是在此等實施形態之中，即使將2個以上組合實行亦可。 Although the embodiments of the present invention have been described above, in the embodiments, two or more combinations may be implemented.

或是，此等實施形態之中，即使是部份性實施1個亦可。 Alternatively, even one of these embodiments may be implemented in part.

或是，此等實施形態之中，將2個以上部份性組合實施亦可。 Alternatively, in these embodiments, two or more partial combinations may be implemented.

又，本發明並非是限定於此等實施形態者，因應必要可以進行各種變更。 Further, the present invention is not limited to the embodiments, and various modifications can be made as necessary.
