800xA Frozen Alarms
Hello,
1. We have ABB 800xA v5.1 and I have found that some of the alarms (analogue) are "Freeze" even if the alarm conditions are not present. Other alarms are just working fine.
2. Is there any way to put dead-band / hysteresis in alarms generated thru expressions.
Thanks & Regards,
Riz.

1. Right click the alarm(s) -> Event Details... -> Take note of Category
Depending on the category (=origin) your options vary. Let me know the category and I’ll guide you further.
2. No

For Alarm Expressions, to my understanding there is no Dead Band band Functionality. But there are Active and Inactive Filter Time functions part of Alarm expressions from 5.1.1.4SP2 which can be used.
