#299 - AVEVA InTouch How to setup the comms between the IO Server and a Rockwell PLC

- Download the PLC project to the CPU and go online from the VM to ensure communication with PLC is working.

- Configure the OCMC ABCIP Driver:

Ensure the type of the connection (e.g., ENB_CLX) is suitable for the CPU model. Set the CPU IP in the ENB_CLX parameters and add the Device Group (e.g., Roll2Roller) in the LOGIX5000_CLX.

- In InTouch HMI edit the Tag Access Names and ensure the access name and topic name are the same as the device group in the OCMC, and the application name is the same as the driver in OCMC.

- Delete the cache on C:\ProgramData\Wonderware\OI-Server\$Operations Integration Supervisory Servers$\OI.ABCIP\CIPTagDB

- Use the program wwClient for debugging and troubleshooting. Create a connection (node: localhost / application: ABCIP_Trads / topic: CRU) and add an Item (PLC tag) and click AdviseEx. This tool tests the data transfer between Wonderware (InTouch, Application Server, Historian) and the PLC through the DAServer.

Wonderware <--- Connection ---> DAServer <--- Item ---> PLC.

Notes: IOT means SuiteLink. DDE is the obsolete protocol. Item error codes: xx1x: no comms to PLC, xx0x: can't access PLC tag, 00c0 healthy PLC connection.

- Ensure the PLC is communicating with the SCADA. When the comms is established, the tags will automatically appear in the OCMC along with diagnostics information.
