FAQ

What’s the Alarm Analysis function?

With this function, you can call up and display sampling data, trend graphs, and operation log when an error occurs based on the time of Trigger/Acknowledge/Recover in Alarm History on the Alarm Message Display screen.

You can examine what kinds of operations were performed and what changed in data before and after the alarm. This is useful for analyzing the cause of the alarm.
