800xa with AC400 connect and thirdparty interface
we have system configuration with 800XA 6.0 with AC450 system,
now we need to interface thirdparty PC for level-2 data exchange ( read & write)
kindly suggest the reliable configuration
The attached slide show that there exist many ways for an OPC client to communicate with an OPC server.
For 800xA for Advant Master, the "Asynchronous Advise" and "Synchronous ReadFromCache" are the by far the most recommended methods in combination with active groups and items with 1, 3 or 9 seconds update rate.
- Download and read the Advant Master Configuration User's Guide, 3BSE030340-600.

- Keep a close watch on ANPER task and channel analyze results on the RTA board and controllers.
