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?
For System internal communication between controller and operator station of 800xA there is no seperate OPC license. This is included in the core license and in the controller licenses of 800xA. To provide information from 800xA to 3rd party systems, where 800xA is a OPC server to a 3rd party OPC client, you need the OPC client connection license.
