How to fetch the data from AC500 PLC's PM5xx-eth to a centralized CHMI 6

ear Sir,

I have to fetch the data from AC500 PLC's PM5xx-eth to a centralized CHMI 6 system, existing computers are identical and having CHMI 6 & Automation Builder 1.2 and on the same network.

There are total 5-6 CHMI 6 & Automation Builder 1.2 system computers with dedicated controllers PM5xx-eth, and I have to fetch the selected data from their controllers, just to display on my centralized CHMI 6 computer without doing any modification in existing system. However all computers are on the same network and dedicated IP address.

Can we use OPC DA only as a reliable solution?

How i can do this thing?

Thanks in advance.

Hello nitinpulastya,

Use OPC DA server supplied with Automation Builder. You can install it from AB installer as "additional software". A single OPC server can connect to tens of PLC (I don't remember if it was 20 or 30 max.), but this number will vary vastly depending on data throughput (number of signals read/written). To use OPC you must generate a symbol file from your PLCs, but that should not change the existing functions of system. Of course importing the data to CHMI will require defining controller using PLC Connect, but as I understand this is not a problem.

Hope this helps,
Mike

Hi MMM,

Thanks for your support.As In my computer, there is neither there OPC file nor Gateway files all these are on local computers.

I am also using OPC DA but how to get the Symbol file from controller, When I use OPC DA it does not browse PLC. please guide me to do the same.

Go to <Project><Options><Symbol
configuration> and then check 'Dump symbol entries'. Click <Configure symbol file> button and choose which part of project you would like to have access to. Compile the project to creaty the symbol file. You may eighter load the aplication to PLC to automaticly store .sym file in Gateway directory or copy the file manually. Then open OPCconfig.exe, deselect <Single PLC> option in File menu. Insert PLCs using <Edit><Append PLC> command. Configure each PLC parameters. That should be enough.

Hi MMM,

I know these things, the problem is that there are so many PLC's and I am not using any logic as the programming and all communication have already done, so now I have to fetch the data from existing running computers or PLCs.

My problem is that how can I copy the .sdb files (gate way) in my computer as the file names are same "Application.sdb" therefore I am looking some solution so that I could use multiple files in my computer.

Thanks for your support.

The applications names are the same on all PLCs? What about the applications themself - are they also the same on all PLCs?

No, only Application (where by clicking we open the Codesys program) name is same in all PLC logic file however the programming is different inside PLC, that's why I am struggling so much..
