Engineering Workplace is not getting Synchronized with Control Builder
In site, we are facing a strange problem with 800xA.
The Engineering Workplace is not getting Synchronized with Control Builder.
If a control module is deleted in workplace , it is still available in Control builder and vice versa.
Ideally, PPA (an OPC client) talks to CBM by OPC server and MMS. PPA (or OPC server) and CBM talks to controller by MMS server in the network.
So I predict, you have issue with MMS server because the Control structure is not getting reflected by changes in CBM. So restart your MMS server and OPC server.
