Description
Technical Field
The present invention relates to a tension controller that controls the tension of a long material such as paper, film (film), wire (wire).
Background
In a conventional tension controller, analog data (analog data) obtained by load conversion of the tension of a material output from a tension detector is processed as a tension input, and while monitoring (monitor) the tension input, a control output is adjusted so as to match a target tension. Such a tension control method is called a feedback (feedback) type tension control. The following tension control method is referred to as open loop (open loop) type tension control, and the open loop type tension control has a function of enabling a user to select two functions, namely, a function of outputting a control output in accordance with a current material diameter by performing an arithmetic process using a roll diameter: a function of inputting a current roll diameter of a material as analog data by using a potentiometer (potentiometer) and an ultrasonic sensor (sensor); and a function of calculating a current material diameter using an accumulated thickness method using a proximity sensor and a rotary encoder (rotary encoder) or using a roll diameter calculation method based on a ratio calculation. Non-patent document 1 discloses a tension control operation such as a feed forward/feedback composite type, in which a feedback type and an open loop type are combined by simultaneously inputting analog data obtained by load conversion of the tension of a material from a tension detector and inputting a proximity sensor and a rotary encoder.
On the other hand, the tension controller includes 2 types of integrated (all-in-one) type and combined (component) type, the integrated type includes a liquid crystal display or a 7-segment (segment) display as a display function on a panel (panel) surface, a dial (dial) or a key switch (key switch) as an operation function, and a power amplifier (power amplifier) function for a magnetic particle clutch/brake (brake) is mounted inside the product, and can be directly connected to the magnetic particle clutch/brake. The tension controllers disclosed in non-patent document 2 and non-patent document 3 are all integrated tension controllers.
The tension controller disclosed in non-patent document 2 has a liquid crystal display and a 7-segment display on the front surface, which are displayed with characters (characters), and performs tension monitoring, parameter setting, and display of a monitoring screen. The operation of changing the setting of each parameter is performed using a key switch and a dial. The key switches for screen jumping include a cursor (cursor) moving key, a screen switching key, a tension setting key, and a manual setting key. The side surface of the device is provided with a volume diameter calculation unit (unit) for function expansion and a connector (connector) for extension. The opening panel has an external connection terminal inside, and is connected to a wiring such as a tension control signal input/output and a network (network) function. The tension controller disclosed in non-patent document 2 amplifies a load signal from a tension detector and converts the amplified load signal into a tension value through a tension correction calculation. The tension calculation input signal linked with the operation or stop of the machine is input, feedback control calculation is executed so that the converted tension value matches the target tension, and the calculation result is output as a tension control signal. According to the tension controller disclosed in non-patent document 2, the control characteristic of the tension control calculation can be adjusted by the value of the control characteristic adjustment parameter.
The tension controller disclosed in non-patent document 2 has taper tension (taper) control calculation as an auxiliary function of the tension control calculation. For example, the internal taper (taper), the external straight taper, or the external polygonal line taper can be switched as the taper tension control calculation in accordance with the setting of the configuration parameter (configuration parameter). The roll diameter signal input is performed from the outside or the roll diameter information is input from the roll diameter calculation means by connecting the roll diameter calculation means to the outside, in order to require the roll diameter information for using the external straight taper or the external polygonal taper. The function of the input/output terminal can be changed by the input/output terminal function assignment parameter, and the winding diameter signal can be input by setting the input/output terminal function assignment parameter.
The tension controller disclosed in non-patent document 2 has a function of switching between validity and invalidity of numerical value input through a dial on a panel surface, and information on the validity and invalidity can be stored in a storage unit as parameter key lock (parameter key) information.
The tension controller disclosed in non-patent document 2 is capable of inputting a tension calculation signal from a personal computer (personal computer) or a programmable controller (programmable controller), outputting a tension control signal, and setting and monitoring parameters by a network communication function.
Further, the tension controller disclosed in non-patent document 2 switches the state of the auxiliary function of the tension control calculation based on the setting of the configuration parameters and the presence or absence of connection of the roll diameter calculation means, and therefore can switch the screen jump according to the setting content of the parameters and the presence or absence of connection information of the roll diameter calculation means by screen jump.
The tension controller disclosed in non-patent document 3 is a product in which usability of a user is specifically set, and is different from the tension controller disclosed in non-patent document 2 in appearance in that a liquid crystal display on the front surface of the tension controller disclosed in non-patent document 3 is a dot matrix character (dot matrix character) display, key switches for screen jump are a screen switching key and a function key, a key lock key (key lock key) for switching between validity and invalidity of numerical value input for each parameter is provided, a connector for adding a winding diameter calculation unit for function expansion is not provided, and a terminal for network connection is not provided. The tension controller disclosed in non-patent document 3 does not have a function expanding unit, does not have an external polygonal-line taper for taper tension control calculation, and does not have a network communication function, as a difference in function from the tension controller disclosed in non-patent document 2. In addition, since the feedback tension control operation has different operation methods, the control characteristics are different in the initial state.

The tension controller disclosed in each of the above non-patent documents differs in display function, operation function, or operation function depending on a product, and cannot change the display content or operation method, so that if a user is accustomed to an existing product, it is necessary to newly grasp the display content, screen skip, operation method, or operation function when using another product.

The screen data (data) respectively matched with a plurality of existing products can be provided for the user through the programmable display, so that the user can arbitrarily select the display content of the programmable display, and the function that the user is used by the user can be realized.
However, since the operation functions are different for each product, it is necessary to mount the operation functions in accordance with the product having the largest operation function, and the number of required configuration parameters increases for a user who uses a product having a small operation function, and thus the workload of the user in setting the parameters to the tension controller increases.

Next, a tension controller according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the present embodiment.
Provided is an implementation mode.
Fig. 1 is an external view of a tension controller according to an embodiment. Fig. 1(a) is a front view of the tension controller, and fig. 1(b) is a rear view of the tension controller. The tension controller 100 is provided with: a programmable display 1; a 7-segment display 3 for displaying the tension value calculated by the tension correction or displaying the tension control signal output value of the result of the tension control calculation; a dial 4 which is a means for setting a parameter setting value displayed on the programmable display; a manual control switch key switch 5 for forcibly jumping the screen of the programmable display to a manual setting screen; an automatic control switching key switch 6 for switching automatic or manual of a control mode (mode); and a key lock key switch (key lock switch)7 for prohibiting setting of the set value of each parameter.
If the automatic control switching key switch 6 is pressed, the screen of the programmable display is forcibly jumped to the tension setting screen, and if the manual control switching key switch 5 is pressed, the screen of the programmable display is forcibly jumped to the manual setting screen. When the key lock key switch 7 is pressed, not only the setting of numerical values by the dial 4 but also the input of numerical values on the touch panel (touch panel) of the programmable display are inhibited.
The programmable display 1 displays not only a setting screen for each parameter, but also key switches for switching screen contents are arranged on the touch panel of the programmable display 1. The key switch is an operation unit for screen jumping and a unit for setting a parameter setting value by numerical value input. In other words, the parameter setting includes a method of inputting a numerical value by operating a touch panel of the programmable display and a method of setting by operating the dial 4. The programmable display 1 also displays a check error (error) when the operation function is manually set.
The tension controller 100 is provided with: a connector 2 for transferring screen data, which is connected to a personal computer not shown; an external connection terminal 8 to which each contact signal or an analog (analog) signal as a tension calculation signal is input and which outputs each contact signal or an analog signal as a tension control signal; and a connector 9 connected to the function expanding section 110.
The connector 2 is connected to a personal computer, and by switching a plurality of screen data described later by an operation of the personal computer, screen display contents displayed on the programmable display are changed, and key switches on the touch panel of the programmable display 1 are changed. The connector 9 receives a reel pulse (pulse) signal and a main pulse (major pulse) signal for performing a reel diameter calculation, outputs a rotational speed limit signal for limiting the rotational speed of a motor (motor) of the reel, and receives a signal for determining the presence or absence of connection of the function expanding unit 110.
Fig. 2 is an external view of a function expanding portion connected to the tension controller according to the embodiment. Fig. 2(a) is a front view of the function expanding portion 110, and fig. 2(b) is a rear view of the function expanding portion 110. An external connection terminal 10 is provided on the front surface of the function expansion unit 110, and an external connector 11 connected to the connector 9 of the tension controller 100 is provided on the rear surface. The function expansion unit 110 has a function of inputting a reel pulse signal or a main pulse signal detected by a reel sensor (not shown) to the external connection terminal 10 and outputting a rotation speed limit signal for limiting the rotation speed of the motor of the reel from the external connection terminal 10, as various option functions for complementing the function of the tension controller, for example, in the case where the function expansion unit 110 is a reel diameter calculation adapter (adapter). When the function expansion unit 110 is a winding diameter calculation adapter, the above-described reel pulse signal, main pulse signal, and rotation speed limit signal are transmitted between the external connector 11 and the connector 9, and a signal for determining whether or not the function expansion unit 110 is connected to the tension controller 100 is also transmitted. In addition, at the external connector 11, power is supplied from the tension controller to the function expanding portion 110 via the connector 9. Therefore, the function expanding unit 110 can be operated without performing input of power from the external connection terminal 10.
Next, the internal structure of the tension controller will be explained.

Fig. 6 is a diagram showing an example of functions executed by the 2 nd control unit shown in fig. 3. Fig. 7 is a diagram showing an example of data stored in the RAM or flash memory mounted in the 2 nd control unit shown in fig. 3.
The tension controller 100 shown in fig. 3 includes a programmable display 1, a 1 st control unit 15, a 2 nd control unit 12, and an external connection terminal 8.

As shown in fig. 4, the 1 st control section 15 has a 1 st control function 15-1 and a 2 nd control function 15-2. The 1 st control function 15-1 includes a tension control calculation unit 15-1a as a tension control function and a taper tension control calculation unit 15-1b as a taper tension control function. The tension control operation unit 15-1a performs, for example, a feedforward/feedback combined type tension control operation, an open loop type tension control operation, a feedback type tension control operation, or a control characteristic adjustment. The taper tension control arithmetic section 15-1b performs taper control such as direct taper (direct taper), external broken line taper, external straight taper, and internal taper. The 2 nd control function 15-2 has the following functions, namely: an operation function manual setting check 15-2a, an operation function manual setting 15-2b, a main body operation function valid/invalid switching 15-2c, an operation function automatic switching 15-2d, a configuration parameter automatic setting/setting limit 15-2e, a network input/output function switching 15-2f, an input/output terminal function switching 15-2g, and a tension correction calculation 15-2 h.
As shown in fig. 5, the RAM 16 or the EPROM 17 stores the following information: a control characteristic adjustment parameter 30 for adjusting a control characteristic of the tension control operation function; input/output terminal function assignment parameter 31; configuration parameters 32; parameter key lock information 33; tension control operation switching information 34; network input output function assignment parameters 35; the usage parameter selection information 36; parameter category information 37; action function setting completion information 38; and action function switching information 39. It is assumed that a plurality of pieces of operation function switching information 39 from the pattern (pattern)1 to the pattern n (n is a natural number) are stored in the RAM 16 or the EPROM 17 shown in fig. 5. In the 1 st control unit 15, data stored in the EPROM 17 is read out to the RAM 16 when the power is turned on, and stored and held again when the setting is changed (timing) or the power is turned off. The information stored in the RAM 16 or the EPROM 17 is not limited to this, and the RAM 16 or the EPROM 17 also stores, for example, a hardware unique value for correcting fluctuations (variations) in hardware (hardware) characteristics that the circuit of the tension controller inherently has. The hardware unique value is a value obtained by measuring a characteristic by a factory test or the like and storing the value.
The 1 st control unit 15 configured as described above executes various controls including: analog-digital (analog digital) conversion control of a signal output from a tension detector (not shown), calculation of tension correction, calculation of tension display, analog-digital conversion control of signal input for tension calculation, digital-analog (digital analog) conversion control of tension control signal output, calculation of tension control, calculation of winding diameter calculation using the function expanding unit 110, communication control of data transmitted with the 2 nd control unit 12, communication control with a network, tension display value display to 7 segments, display control of tension control signal output value display to 7 segments, control of operation of setting change by a key switch, or memory (memory) management.
The 2 nd control unit 12 shown in fig. 6 has the following functions: the action function manual setting checkup error display 12-1, forced screen jump 12-2, use parameter selection change warning 12-3, screen jump switch 12-4, and operation function valid/invalid switch 12-5.
As shown in fig. 7, the RAM13 or the flash memory 14 stores, as screen data 40, information including: display information 41, operation information 42, and screen data individual information 43. The screen data 40 correspond to the plurality of screen data 1, 2.. n (n is a natural number) input from the personal computer shown in fig. 3, respectively. The screen data 1 and 2.. n are data related to display contents to be displayed on the display of the tension controller, respectively. For example, the screen data 1 shown in fig. 3 is data related to the display contents displayed on the display of the conventional tension controller shown in the above-mentioned non-patent document 2. The screen data 2 is data related to display contents displayed on a display of the conventional tension controller shown in non-patent document 3. The screen data n is data related to display contents to be displayed on the display of the tension controller other than these tension controllers. In this way, the screen data 1 and 2.. n are data related to display contents to be displayed on the displays of the tension controllers having different display functions. The screen data individual information 43 is information indicating the type of screen data of display contents to be displayed on the screens of the displays of the plurality of tension controllers.
The 2 nd control unit 12 reads the data stored in the flash memory 14 to the RAM13 when the power is turned on, and stores and holds the data again when the setting is changed or the power is turned off.

The function expansion unit 110 includes a connection/non-connection determination circuit 18. When the connection presence/absence determination circuit 18 is connected to the connector 9, a loop circuit is formed between the 1 st control unit 15 and the connection presence/absence determination circuit 18, a digital signal detected by the 1 st control unit 15 becomes a high level (level), and it is detected that the function extension unit 110 is connected to the tension controller 100. When the presence/absence determination circuit 18 is not connected to the connector 9, the digital signal detected by the 1 st control unit 15 goes low, and it is detected that the function expansion unit 110 is not connected to the tension controller 100. In the following description, information indicating whether or not the connection determination circuit 18 is connected to the connector 9 is referred to as "connection presence/absence information". Assume that no connection information is stored in RAM 16 or EPROM 17.
An analog-digital converter 19 is provided between the 1 st control unit 15 and the tension detector signal input terminal 82 and the winding diameter signal input terminal 83, and a digital-analog converter 20 is provided between the 1 st control unit 15 and the tension control analog signal output terminal 86. The analog-digital converter 19 converts the tension detector output signal inputted via the tension detector signal input terminal 82 and the winding diameter signal inputted via the winding diameter signal input terminal 83 into digital signals and outputs the digital signals to the 1 st control unit 15. The 1 st control unit 15 performs a correction value calculation and a tension control calculation using a signal output from the analog-digital converter 19. A tension control output signal as a result of the tension control operation is output to the digital-analog converter 20, and an analog tension control output signal converted by the digital-analog converter 20 is output to the control target via the tension control analog signal output terminal 86.
The automatic setting/restriction of configuration parameters 15-2e and the automatic switching of operation functions 15-2d will be described below.
In order to perform the automatic setting and the setting restriction of the arrangement parameters 32, it is necessary to make a judgment that the user uses the tension controller according to the present embodiment in accordance with which of the existing tension controllers is used, or as a new product, that is, as a tension controller other than the existing tension controller. To perform this determination, the 1 st control unit 15 uses the operation function setting completion information 38 stored in the 1 st control unit 15, the screen data individual information 43 stored in the 2 nd control unit 12, and the information on the presence or absence of connection to the function extension unit 110. In the following description, for the sake of simplicity of explanation, the conventional tension controller shown in non-patent document 2 is referred to as "conventional tension controller 1", and the conventional tension controller shown in non-patent document 3 is referred to as "conventional tension controller 2".
Fig. 8 is a 1 st flowchart of automatic switching determination of automatic setting/setting restriction of configuration parameters and automatic switching of operation functions. Fig. 9 is a flow chart of the automatic switching judgment of the automatic setting/setting restriction of configuration parameters and the automatic switching of the operation function 2. Fig. 10 is a 3 rd flowchart of automatic switching determination of automatic setting/setting of configuration parameters and automatic switching of operation functions. Fig. 11 is a 4 th flowchart of automatic switching determination of automatic setting/setting restriction of configuration parameters and automatic switching of operation functions. Fig. 12 is a diagram showing the 1 st data for generating the processing result of automatic setting/restriction of configuration parameters and automatic switching of operation functions. Fig. 13 is a diagram showing the 2 nd data for generating the processing result of automatic setting/restriction of the configuration parameters and automatic switching of the operation functions. Fig. 14 is a diagram showing the 3 rd data for generating the processing result of automatic setting/restriction of the configuration parameters and automatic switching of the operation functions. The 1 st data shown in fig. 12 is data related to automatic switching of the tension control operation switching information, the 2 nd data shown in fig. 13 is data related to automatic switching of the use parameter selection information, and the 3 rd data shown in fig. 14 is data related to automatic switching of the initial value information. In fig. 12, screen data, function expansion, configuration parameters, and tension control operation switching information are associated with each other. In fig. 13, the use parameter selection information is associated instead of the tension control operation switching information of fig. 12, and in fig. 14, the initial value information is associated instead of the tension control operation switching information of fig. 12. In the data of fig. 13 and 14, the number of the use parameter selection information is 7 and the number of the initial value information is 15, but the number of the use parameter selection information and the number of the initial value information are not limited to these. In addition, "taper tension" is abbreviated as "taper" in fig. 8 to 14.
In fig. 8, when the power of the tension controller 100 is turned on, the operation function setting completion information 38 stored in the 1 st control unit 15 is read (S1001), and it is determined whether the setting of the operation function is completed based on the read operation function setting completion information 38 (S1002). When the setting of the operation function is completed (No in S1002), the operation is completed without switching the operation function data (S1003). If the operation function setting is not completed (Yes at S1002), the screen data individual information 43 stored in the storage unit of the programmable display function is read (S1004).
It is determined whether or not the screen data read out is screen data of the existing tension controller 1 (S1005), and if the screen data is the existing tension controller 1 (Yes in S1005), the connection function expanding unit 110 is read out (S1006). The presence or absence of connection function extension unit 110 is determined based on the read connection presence or absence information (S1007). When the function expanding portion 110 is not connected (Yes in S1007), the taper tension function is set to direct (direct) and is restricted (S1008). If the setting of the taper tension function (S1009) and the setting of the axis switching function (S1010) are performed by the user, the roll diameter calculation function is automatically set to none of the setting values (S1011). The operation function switching information is automatically set to the data No.1 to 8 shown in fig. 12, 13 and 14 in accordance with the set contents (S1012).
If the determination result in S1007 indicates that there is a connection (No in S1007), the taper tension function is set to be internal or directly limited (S1013). If the setting of the taper tension function (S1014) and the setting of the axis switching function (S1015) are performed by the user, the roll diameter calculation function is automatically set to a ratio as the set value (S1016). The operation function switching information is automatically set to the data nos. 9 to 14 shown in fig. 12, 13 and 14 in accordance with the set contents (S1017).
As a result of the determination in S1005, if the screen data is not the screen data of the existing tension controller 1 (No in S1005), it is determined whether or not the read screen data is the screen data of the existing tension controller 2 as shown in fig. 9 (S1018). If the screen data is the existing tension controller 2 (Yes at S1018), the connection function expansion unit 110 is read (S1019). The presence or absence of connection function extension unit 110 is determined based on the read presence or absence of connection information (S1020). When the connection is not made (Yes in S1020), the taper tension function is automatically set to none (S1021), the axis switching function is automatically set to none (S1022), and the winding diameter calculation function is automatically set to none (S1023). The operation function switching information is automatically set to data No.15 shown in fig. 12, 13, and 14 (S1024).
If the connection is present as a result of the determination in S1020 (No in S1020), the taper tension function is automatically set to the set value (S1025), the axis switching function is automatically set to the set value (S1026), and the winding diameter calculation function is automatically set to the set value (S1027) as the ratio. The operation function switching information is automatically set to data No.16 shown in fig. 12, 13, and 14 (S1028).
As a result of the determination in S1018, if the screen data is not the existing tension controller 2 (No in S1018), it is determined whether or not the screen data read out is the screen data of a new product as shown in fig. 10 (S1029). If the screen data is a new product (Yes in S1029), the information of the connection/disconnection function extension unit 110 is read (S1030). The presence/absence of connection function extension unit 110 is determined based on the read connection presence/absence information (S1031). If the connection is not made (Yes in S1031), if the setting of the taper tension function (S1032) and the setting of the shaft switching function (S1033) are performed by the user, the roll diameter calculation function is automatically set to the set value none (S1034). The operation function switching information is automatically set to the data nos. 17 to 26 shown in fig. 12, 13 and 14 in accordance with the set contents (S1035).
If the connection is determined to be present as a result of the determination in S1031 (No in S1031), the taper tension function is set to be internal or restricted as it is (S1036). When the setting of the taper tension function (S1037), the setting of the axis switching function (S1038), and the setting of the winding diameter calculating function (S1039) are performed by the user, the operation function switching information is automatically set to the data No.27 to 38 shown in fig. 12, 13, and 14 in accordance with the contents of the settings (S1040).
As a result of the determination at S1029, if the screen data is not a new product (No at S1029), as shown in fig. 11, it is determined that the screen data is user generated data, and the information of the function expanding unit 110 is read (S1041). The presence/absence of connection function extension unit 110 is determined based on the read connection presence/absence information (S1042). When the connection is not made (Yes in S1042), the taper tension function is automatically set to none (S1043), the axis switching function is automatically set to none (S1044), and the winding diameter calculation function is automatically set to none (S1045). The operational function switching information is automatically set to data No.39 shown in fig. 12, 13, and 14 (S1046).
If the connection is found as a result of the determination in S1042 (No in S1042), the taper tension function is automatically set to none, the axis switching function is automatically set to none, and the winding diameter calculation function is automatically set to a ratio of the set value (S1047 to S1049). The operational function switching information is automatically set to data No.40 shown in fig. 12, 13, and 14 (S1050).
As for the data shown in fig. 12, when the screen data of the programmable display is the existing tension controllers 1 and 2, the feedback control (FB) is performed regardless of the presence or absence of connection of the function expanding unit 110, and when the screen data of the programmable display is a new product, the switching between the feedback control (FB) and the feedforward/feedback composite control (FF/FB) is performed in accordance with the presence or absence of connection of the function expanding unit 110.
With regard to the data shown in fig. 13, when the usage parameter selection information is ○, it is determined that the corresponding parameter is in a usable state, and the operation of the tension controller is switched in accordance with the set value of the parameter.
Switching is performed by the data shown in fig. 14, that is: control gain (gain) of feedback control, function assignment of input/output terminals, and function assignment of network input/output. When the screen data is the existing tension controllers 1 and 2, the initial values of the parameters are determined in accordance with the screen data, and when the screen data is a new product, the initial values of the parameters are largely changed in accordance with the presence/absence of connection information and the set values of the configuration parameters 32. In addition, when the screen data is user generated data, since it is not known which function the user will use, the use parameter selection information and the parameter initial value information are set to the minimum.
As described above, the 2 nd control function 15-2 of the 1 st control unit 15 executes the processing shown in fig. 8 to 11, thereby executing the determination of how the user wants to use the tension controller in accordance with the operational function setting completion information 38, the screen data individual information 43, the information on whether or not the function extension unit 110 is connected, and the set value of the configuration parameter 32, and switching the operational function switching information to the data shown in fig. 12 to 14 in accordance with the result of the determination. This can simplify the parameter setting by the user.
Fig. 15 is a diagram showing data in a table format indicating settable conditions in the case where the tension control calculation information and the use parameter selection information are manually set. The data in fig. 15 is such that tension control calculation information, information on whether or not the function expansion unit is connected, and arrangement parameters are associated with each other as settable conditions. When the tension control calculation information and the use parameter selection information are manually set, the operation function manual setting checkup 15-2a determines whether or not the arrangement parameter and the information on the presence/absence of connection of the function expanding unit 110 match the data shown in fig. 15, and when they match, the operation function manual setting 15-2b validates the contents of the manual setting. In the case of inconsistency, the manual setting 15-2b of the operation function invalidates the contents of the manual setting, and displays the verification error on the programmable display.
Fig. 16 is a diagram showing an example of parameters of the tension controller. For each parameter, the device number, the setting content, and parameter type information for determining the type of the parameter are associated. The tension setting at D0 and the manual setting at D1 are common parameters that can be used in all states, and D4 to D7 are parameters related to tension correction using parameter selection. In the illustrated example, the tension correction is in a usable state. When there is no such usable parameter, the 2 nd control function 15-2 displays a warning for an access (access) to attempt to change the set value so that the tension correction using the parameter selection information 36 is made usable based on the parameter type information 37.
D1004 is a set value for switching the tension control calculation, D1008 to D1010 are set values for the arrangement parameters, and D1016 to D1022 are set values for selecting the use parameters. These setting values are checked on the programmable display via the programmable display communication unit 21, and screen skipping of unnecessary parameters can be switched so as to match these setting values. When the functions of other existing tension controllers or new functions matching new products are to be used through the screen data of the existing tension controllers, the screen jump can be switched by changing the settings of the tension control operation switching, configuration parameters or use parameter selection so that the parameter setting screens of the functions of other existing products or new functions matching new products are displayed, and the functions can be used.
Next, switching of the input/output function of the network communication unit 22 will be described.
Fig. 17 is a view 1 showing an input/output function switching function of a network communication unit of the tension controller according to the present embodiment. Fig. 18 is a view 2 showing an input/output function switching function of a network communication unit of the tension controller according to the present embodiment.
When a personal computer or a programmable controller as a master is connected to the network communication connection terminal 81 shown in fig. 3, network input/output data of the tension controller includes a remote register (remote register) RWw that is a signal transmitted from the personal computer or the programmable controller as the master to the tension controller 100 as a slave (slave) station and a remote register (remote register RWr) that is a signal transmitted from the slave to the master. The parameter setting method from the network communication unit 22 includes the following 2 types: a continuous setting method of inputting a set value of a parameter assigned to the remote register RWw; and a request command execution method for setting parameters arbitrarily selected by a user through a request command (command), a request code (code), and setting data. The continuous setting method is to perform continuous writing into the RAM for writing parameters, and the request command execution method enables the user to arbitrarily select writing into the RAM and the EPROM by the request command. The parameter monitoring method from the network communication unit 22 includes 2 kinds of methods: a continuous monitoring method of monitoring a value of a parameter allocated to the remote register RWr; and a request command execution method of monitoring a parameter arbitrarily selected by a user through a request command, a request code.
In the tension controller according to the present embodiment, the parameter setting can be switched between the presence and absence of use of the continuous setting, and when the continuous setting is used, half of the remote register RWw is used as the continuous setting to assign the function, and the remaining half is used as the execution request command to assign the function. In the case where the continuous setting is not used, all the remote registers RWw are used as the execution request command to allocate the function. In addition, when the continuous setting is used, the user can arbitrarily set the remote register RWw to be used as the continuous setting of which parameter.
The parameter monitoring can switch the presence or absence of the execution result of the use request command, and in the case of the use request command execution result, the function of the request command execution result is assigned to the remote register RWr in accordance with the number of execution request commands of the remote register RWw. When the result of the request command execution is not used, the function is allocated to all the remote registers RWr for continuous monitoring. In addition, the continuous monitoring can be arbitrarily set by the user as to which parameter to use as the continuous monitoring, similarly to the continuous setting.
The setting of the function assignment of the continuous setting and the continuous monitoring can be automatically set by the automatic switching of the operation function described above, and the automatic function assignment of the network input/output according to the state determination results shown in fig. 8 to 11 can be realized. In fig. 17 and 18, the amount of information of each remote register is 8, but the amount of information of the tension controller is not limited to this.
Next, the linkage of the main body operation function of the tension controller of the present embodiment with the display function and the operation function of the programmable display will be described.
Fig. 19 is a diagram showing a part of a list of M devices having a programmable display communication function. The programmable display has a function of forcibly jumping a screen or switching the validity/invalidity of an operation function based on data information that can be transmitted to the tension controller through a programmable display communication function, which is an M device or a D device called a trigger (trigger) function. When an automatic control switching key of an operation function of a tension controller is pressed, a tension setting screen jump trigger of M1000 is turned on, and if the programmable display confirms that M1000 is turned on through communication, the screen of the programmable display jumps to a tension setting screen by using the trigger function. At the same time of jumping to the tension setting screen, the next input of the automatic control switching key is prepared by turning off M1000. Similarly, when the manual control switch key is pressed, the manual setting screen skip trigger of M1001 is turned on, and if it is confirmed by the programmable display through communication that M1001 is turned on, the screen of the programmable display is skipped to the manual setting screen by the trigger function. At the same time of jumping to the manual setting screen, the next input of the automatic control switching key is prepared by turning off M1001.
Further, M1016 to M1047 serve as key lock signals of parameters, and if the key lock key is pressed when the setting screen of the parameter (1) is displayed on the programmable display, the key lock of the parameter (1) of M1016 is turned on and the setting of the parameter (1) is in a disabled state, and if the programmable display confirms that M1016 is turned on through communication, the numeric input of the parameter (1) of the programmable display is disabled by the trigger function. Further, if M1016 is turned on, the numeric value input from the dial of the main body is also disabled, and the setting is disabled through the main body panel surface. If the key lock key is pressed in this state, M1016 is turned off, numerical value input from the programmable display and numerical value input from the dial of the main body become valid. Similarly, the on/off of M1017 to M1047 can be switched to enable/disable the numeric value input of each parameter. In fig. 19, the number of parameter key locks of the M device is 32, but the number of parameter key locks of the tension controller according to the present embodiment is not limited to this.
The configurations described in the above embodiments are merely examples of the contents of the present invention, and may be combined with other known techniques, and some of the configurations may be omitted or modified within a range not departing from the gist of the present invention.
