Difference event time from AC800M OPC and IEC61850 OPC in event list
As per attached picture, there is difference in the event time for the AC800M OPC and IEC61850 OPC event.
As nodes, controllers and IED are having same time source and no big time difference found. However the IEC61850 device event had stamp difference time from system time in event list.
Pic 1 is the configuration for time service group.
Pic 2 is the time difference for the between nodes.
Pic 3 is the controller clock synch
Pic 4 is the event from the controller
Pic 5 is the event from the IEC61850.
Any advices on this matter
The IEC 61850 is fetching time from the IED, you can see the same time in the CET for that particular logical node.
So check the following things.
1. Ensure the time in CET for that particular logical node.
2.Check the time syn configuration in CET. Normally should in tick that.
3. check the IED is properly sync with GPS
