800xA 6.0.3, OPC Third party communication.
I had communiacted thirdparty opc system by doing dcom configuration(and joined it in our Domain). They are able to browse our structure and getting our live values. As we need to get their signal they dont have any OPC server to access them. So i was sending some spare variables and they write on it. But while writing like this our opc DA is getting blind in our system.
Update rate has been increased in other system and tried, but no improvement
I assume they are writing to the xA "surrogate" OPC server ?
Your spare variables, are they from General Properties aspect or where did you create them, in controller, which controller if so ?
If it is in controller, you can as a workaround move your variables to General Properties and Property Transfer (xA-server to Controller) aspects.
