Hello,
I'm working on an existing Wonderware InTouch project. For now, InTouch communicates with a DDE Server (PCDDE) wich is connected to 4 S7-400 PLCs over Ethernet.
I would like to replace the DDE Server with an OPC Server + FSGateway. I already have tested the setup on a spare computer and PLC and everything works fine.
My problem is with some of the Tagnames' Item Name in InTouch. For some reason, the I/OReal Item names are appended with a "F" suffix.
I've search for an explanation about this suffix but I can't find anything.
With the suffix the communication with the PLC works fine trough the PCDDE server but it won't trough the OPC server. If I remove the suffix everything works well.
Can you tell me what is that suffix for ? And if there is a way to make this work without removing the suffix from all the tags..
Thank you in advance.
Gilles
