What does the logfile say? (C:\ABB Industrial IT Data\Control IT Data\OPC Server for AC 800M\LogFiles\Session.LOG)
Ping and RNRP use other ports and protocols than the OPC Server does. A successful ping does not necessary mean that the MMS communication between the OPC Server and the controller is OK. For OPC DA, the OPC Server also need access to the configuration files created by Control Builder.
Is the MMS Server OK (C:\ABB Industrial IT Data\Control IT Data\MMS Server for AC 800M\LogFiles\Session.LOG)?
