800xA 6.0 + Advant system.(Message list)
Below the picture is my customer site.
Problem is 2 or 3 duplicate message in unit message list.
How can resolve the this problem.
1. What controller (PLC) is used?
2. Make sure Event Collector service is properly setup (redundant service providers must share same service group or else duplicates may be generated). In principle, a 6.0 system shall have same Event collector service configuration as in the previous versions.
