Dealing with alarms
Prerequisites
- Release >= v5.1
An alarm can have the following statuses:
| Icon | Operation | Description |
|---|---|---|
| Notified | An alarm has come from the PLC. | |
| Closed | Alarm is closed/machine is online. | |
| Gone, not acknowledged | Alarm has gone from PLC, but no user has acknowledged. | |
| Received, and acknowledged | Alarm has come from PLC, and user has acknowledged. However, PLC has not yet reported that the alarm has gone. |
The corresponding users are notified when the alarm status is "Arrived" (until a user acknowledges the alarm or the alarm cancels itself).
Note
If an alarm is not acknowledged by a user and the status is "Not acknowledged", the alarm is still "active". If the alarm is repeated by the PLC, the time of the original alarm applies. The alarm history can be viewed in the details.
