Can a Integer represent alarms for different values??
I have a OPC-server that reads data out of a fire detection system. And each detector has one integer where each value represents different status.
Value 5 = stand-by OK
Value 16 = Fire Alarm!
Value 37 = Maintenance
Value 72 = Fire Warning!
I use these values to change the visualisation of the detector.
But I also want value 16 and 72 as a Alarm-line and Event-line in the Alarm-list, how can I do that? Is this even possible in 800xA
Hope you can help!!
If you are reading the values from third party OPC server directly to 800xA, you can use Alarm Expression aspect.
The Alarm Expression Aspect enables the defining of a condition, that when reached, will generate an alarm.
When creating a new Alarm Expression, it is possible to choose two different message types: alarm or event
