MBL Alarm Time Differences
We have logic that will automatically suppress an alarm (MBL) when a motor is shut off.
When the motor is started, the suppression is removed. It works exactly as intended.
However, I noticed that the ActiveTime in the alarm list (Common Process Alarm List Configuration template) is not correct. The Event time is correct. The Active Change Time is also different.
If I look at an alarm that is not MBL, the three times all agree with each other.
We are running SV5.1/FP4. Has anyone else seen this discrepancy.
