Hi All,
Has anyone had success with a VIPA PLC talking to Citect using PSDirect Driver over Ethernet?
The current situation is Citect V7.1 on WinXp communicating to a VIPA CPU313C-2DP with a CP343-1 Ethernet module. Communications is achieved using a "VIPA OPC" server. Things are currently working, but if 1 extra tag is added to Citect, then after re-compiling and restarting the project, communication fails. i.e. #Coms on all values. The new citect tag is generated by copying an existing tag, renaming it and modifying the address. The new tag address already existed in the PLC. I have no experience with OPC servers, let alone VIPA OPC servers, but I have had success with Siemens S7-300 and PSDirect.
As the VIPA can be programmed using the Step 7 software (V5.5), I am wondering if the Citect PSDirect drive will also work with the VIPA PLC.
Any thoughts or suggestions would be helpful
Thanks
Woolie
