Clock Drift out of Range ABB Safeguard AC 415. 800xA Ver4.1
We have Advant controller AC 450 and Safetguard AC 415 installed at our facility. These are connected to ABB 800xA Ver4.1 via MB300 network (Net 13 & 14). For time syncing we use DC server as master. However we have seen recently seen this continuous error of clock drift out of range at one F&G node (network 14 node 31). No other node shows this error. However our clock drifts by 10mins every 4 to 5 weeks and we make manual adjustments in DC after 5 weeks.
The alarm which we are seeing is 20-03-31 14:27:53:633 TIME SYNC Clock drift out of range Clock drift out of range Net 14 Node 31 Any idea what to check for this?
