Dear All,
I've been struggling for a week to connect CitectSCADA v7.2 to M340 PLC through OFS and things aren't working out
Here's the setup:
I programmed a P34 2020 PLC with a simple ladder diagram using Unity Pro XL and I exported all variables (7 bool/ebool) with right-click on "Variable & FB instances" -> Export.
The PLC is connected to the PC through Ethernet.
Using OFS Configuration tool I made an Alias for the PLC, and then checked the OFS using the OFS Client, no errors was shown in the OFS diagnostic window and I could read and write on variables through the client. Tried this using STU and XVM files for alias.
In CitectSCADA, I did the following: New project -> new cluster -> new address (local 127.0.0.1) -> new IO server, used the local address -> Express Wizard and chose the following options: External I/O Device, OFSOPC, Address is Alias name, didn't check link, -> finish -> change address in Board to 1000 (same rate used in the OFS Client).
Then I built the project and started Computer Setup Wizard: Server and Control Client (didn't check Multi-Process), Stand alone, entered password.
Now I couldn't import tags (Tools > Import tags) no matter what options I choose, and if I run the project (I made a simple graphics page) here's the diagnostic window:

And of course the rectangles associated to tags are hashed.
Finally if I use MODBUS/TCP Ethernet with fastlinx in Express setup and put the PLC address, I was able to import tags but they wouldn't be read or written at run.
Any help is greatly appreciated! Thanks in advance
