we have 3 as and 3 cs in our plant
when ever the alarm occurs for motor or any object it is logging 3 times in the list with same time
how to fix this logging of same message
1. Verify that all event collectors for a MB300 control network share the SAME service group (acting service/standby). If not, each will assume service state and individually report alarm and event to the alarm manager.
2. Bring more details (configuration, exact event details, etc)
By your report and attached document it seems like you have misunderstood how to setup redundancy for 800xA for Advant Master.
There can only be one (1) Event Collector group connecting to the same MB300 control network (remember network number 11, 12, 13, ... 19 counts as the same network decade 10 or simply "net 1" if there is routed access across them, i.e. SLTARG works from x to y).
You have three Event Collector groups, if they connect the same MB300 control network you will also have 3x alarms and 3x events.
-> reduce the number of Event Collector groups for the same MB300 control network down to one singular group.
You can, e.g. if there is a large number of controller nodes, elect to split up the 800xA configuration of one MB300 control network to allow additional service groups and providers to share application load. Special event filtering is required then. For details, please refer to pages 126 thru 128 in the 800xA for Advant Master Configuration, 3BSE030340-600 A. This feature is not unique for v6, the same theory can be applied to all versions of 800xA for Advant Master.
