Then it seems to be a network problem. The OPC Server loses contact with four controllers (both OPC DA and OPC AE) and then the connection is reestablished. Where does the message "OPC DA server stop . the OPC servo terminated unexpectedly" show?
On which version of system problem is happening?
On what condition its happening means on downloading to controller?
whther OPC DA of AC800M controller Or for OPC DA of Device management profius HART (DMPH)is terminating unexpectedly?
Since by default both the service provider will get the same name when confgiure through control network for AC800M & during OPC configure for DMPH it will create with same name hence be ensure how many kinds of OPCDA service providers are created in service str.
We had same kind of issue faced in 800xA5.1 FP4 revD but its was for DMPH that was happening whenver we try to upload a HART device.
