Priority | Class | Meaning |
---|---|---|
0 to 15 | 0 | Total failure, results in blocking the operation enablement. |
16 to 31 | 1 | Total failure, results in blocking the operation enablement. |
32 to 47 | 2 | General failure. |
48 to 63 | 3 | General failure. |
Alarm Class is used to group multiple priorities into one category. This category is then used for reporting between different alarm blocks (AlarmsAggregator, AlarmsExtender, and AlarmsCoupler) using the AlarmsStatus structure.
If the priority is odd, it will automatically reset after it ceases.
For even classes, the corresponding alarm output (Alarm*Flag) remains active even in the remembered alarm state (i.e., Memory, AckedMemory). For odd classes, it is active only if the alarm itself is active (i.e., Active, ActiveAcked).
Name | Data Type | Retain | Mandatory to Connect | Meaning | |
Alarm1 | AlarmTrigger | No | No | Alarm Input 1 | |
Alarm2 | AlarmTrigger | No | No | Alarm Input 2 | |
Alarm3 | AlarmTrigger | No | No | Alarm Input 3 | |
Alarm4 | AlarmTrigger | No | No | Alarm Input 4 | |
Alarm5 | AlarmTrigger | No | No | Alarm Input 5 | |
Alarm6 | AlarmTrigger | No | No | Alarm Input 6 | |
Alarm7 | AlarmTrigger | No | No | Alarm Input 7 | |
Alarm8 | AlarmTrigger | No | No | Alarm Input 8 | |
Reset | bool | No | No | Reset Alarms | |
Acknowledge | bool | No | No | Acknowledge Alarms | |
Enable | bool | No | No | External enable for subsequent technology (enables the output RunEnabled) | |
Status | AlarmsStatus | No | No | Extended input for additional alarms | |
StartupDelay | time | No | No | Startup delay after all alarms are reset | |
HornActiveInLowPrio | bool | No | No | If true, the horn is active even when a low priority alarm occurs. This only works for alarms directly on the aggregator, not for extended blocks connected via Status |
