Abstract
The invention discloses a method for obtaining a power station ID flexibly by employing an S7 200PLC. And thus the previous processing way in which a fixed ID address is set in a program is broken. The provided method comprises: a status word MW0 is set and corresponding ID values are assigned to the status word MW0 by corresponding to different power station ID addresses; and in a communication program with a remote end, an ID address in upper computer data is compared with the data value of the status word MW0; if the ID address in upper computer data is consistent with the data value of the status word MW0, feedback of the power station data is carried out; and otherwise, no data feedback is carried out. Because all power stations can share one S7 200 PLC program, the number of archived programs is reduced, the operation requirements of the operator downloading programs are reduced, the workload of the operator downloading programs is reduced, and resources are saved. And more power stations with more extended ID addresses can be connected to carry out communication with the remote end.
Description
Technical field
The present invention relates to a kind of method obtaining power station ID, be specially a kind of method being obtained power station ID by S7200PLC flexibly.
Background technology
Current user's request can carry out communication (see accompanying drawing 1) with several power stations by a set of remote port surveillance equipment 3 simultaneously, and the structure in power station, electrically, function, output interface be all consistent, the communication of question-response formula is carried out by remote-control communication cable 2, S7200PLC module 1 in remote port surveillance equipment 3 and power station, so necessarily require the ID address in each power station different.
Several power stations need to carry out remote-control communication with remote port surveillance equipment 3 simultaneously, for remote port equipment 3, need the data message being distinguished different power station by the ID address that identification power station is different.For power station, need to identify ID address in the data of remote port inquiry consistent with the ID address set in self program after the data message in just corresponding this power station of feedback.
Way is before: in a program for the power station of different ID addresses sets fixing ID address, as 1# power station (2# power station, 3# power station), setting software I D address be 16#1001(2# power station setting ID address be 16#1002,3# power station setting ID address be 16#1003), the ID address in host computer data and numerical value 16#1001(16#1002,16#1003 is judged in PLC program) equal, then the corresponding corresponding data of PLC program feedback are to remote port, otherwise not feedback information.A few cover power station if supplied simultaneously, require that the program of different (ID arranged in program is consistent with the hardware ID in power station) is downloaded in the power station of corresponding different I D address, then must preserve the program of several different I D address simultaneously, or when only having the program of an ID address, will corresponding ID address (numerical value 16#1001 is adjusted to 16#1002 or 16#1003) in first change program before downloading, then continue to download in the power station of corresponding ID address.How require that the operating personnel downloaded have grasped downloads outside S7200PLC program, also requires that operating personnel simply can understand program and can do simple program change work, improves the requirement of the operating personnel downloaded.If power station is on-the-spot user, there is the identical ID address of the programming in two (or more than two) power stations simultaneously, the on-the-spot program again downloading different I D address must be arrived, or change and again downloaded the S7200PLC module of different I D address program, human and material resources, the consumption of financial resources and stand-by period certainly will be increased.
Summary of the invention
The object of the invention is to address the aforementioned drawbacks, and propose a kind of method being obtained power station ID by S7200PLC flexibly, the program quantity the method reducing filing, the operation requirements reducing the operating personnel downloaded, decrease the operating personnel downloaded workload, economize on resources.
The technical scheme that the present invention solves is: a kind of method being obtained power station ID by S7200PLC flexibly, by doing following process in S7200PLC program, can guarantee that the power station of different ID addresses shares a program, it is characterized in that method step is as follows:
(1) the concrete ID value in power station is represented with a status word MW0, according to the different hardware ID in power station, corresponding ID value assignment is carried out to status word MW0;
(2) suppose that the ID arranging the 1st power station is 1#, then status word MW0 assignment is 16#1001; Suppose that the ID arranging the 2nd power station is 2#, then status word MW0 assignment is 16#1002; Suppose that the ID arranging the 3rd power station is 3#, then status word MW0 assignment is 16#1003; The like, remote port communication apparatus simultaneously will with 10 power station communications, then the ID in the 10th power station is 10#, then status word MW0 assignment is 16#100A;
(3) with the program of remote port communication, compared with the value of status word MW0 the ID address in the host computer data of reception, identical, then the corresponding data of feedback are to remote port communication apparatus, otherwise not feedback information;
(4), after downloading, the ID address in automatic program identification power station, does not need first to identify that power station ID downloads the program being provided with corresponding ID address more artificially.
Technique effect of the present invention: the program quantity decreasing filing, the operation requirements reducing the operating personnel downloaded, the workload decreasing the operating personnel downloaded, the possibility decreasing user's Site Service of going on business, the power station access immediately can expanding more ID address and remote port carry out communication.

Embodiment
As shown in Figure 2, the present invention this come work and enforcement like this, a kind of method being obtained power station ID by S7200PLC flexibly, by doing following process in S7200PLC program, can guarantee that the power station of different ID addresses shares a program, as long as the operating personnel downloaded know that the operation how to download is all right, the phenomenon that the hardware ID in the ID of program and power station is inconsistent can not be caused.If the power station that existence two (or more than two) ID addresses are identical is on-the-spot user simultaneously, as long as the hardware ID address in adjustment hardware setting power station, automatic program identification power station hardware ID thus the ID of reprogramming, complete different power stations, ID address and the communication of remote port surveillance equipment; It is characterized in that method step is as follows:
(1) the concrete ID value in power station is represented with a status word MW0, according to the different hardware ID in power station, corresponding ID value assignment is carried out to status word MW0;
(2) suppose that the ID arranging the 1st power station is 1#, then status word MW0 assignment is 16#1001; Suppose that the ID arranging the 2nd power station is 2#, then status word MW0 assignment is 16#1002; Suppose that the ID arranging the 3rd power station is 3#, then status word MW0 assignment is 16#1003; The like, remote port communication apparatus simultaneously will with 10 power station communications, then the ID in the 10th power station is 10#, then status word MW0 assignment is 16#100A;
(3) with the program of remote port communication, compared with the value of status word MW0 the ID address in the host computer data of reception, identical, then the corresponding data of feedback are to remote port communication apparatus, otherwise not feedback information;
(4), after downloading, the ID address in automatic program identification power station, does not need first to identify that power station ID downloads the program being provided with corresponding ID address more artificially.
