Answer question
When do I need 800xA OPC Client Connection?
System: 800xA 5.1
In my test system I have single AS/CS server. On this server three OPC servers are available:
- AfwOPCDASurrogate Class
- AfwPOCDAServer Class
- OPC DA Server for Control Network.
Last one is AC800M OPC server. Using it, I can see all of controller resources.
Do I need license 800xA OPC Client Connection for connection to OPC DA Server for Control Network (AC800M OPC server) or this license is used only for first/second servers AfwOPCDAxxx?
Thanks.
