PLC Connect- Configure Alarm of a Analog Signal in the faceplate of the object
HI,
System 800xA 5.0 SP2 Rev D
PLC Connect
We have an analog signal and want to create four alarms (LL, L, H & HH) depending on the variable. Using Alarm Event Configuration aspect (Limiter 1- Limter 8), we were able to generate alarm in the Alarm and Event list. We need to display the alarm (using a bit each for LL, L, H & HH) in the faceplate Element.
Please suggest to do configure the same.
Thanks

Hi,
This may not be a direct solution to your requirement, but may be useful.
In the faceplate element where the alarm status should be shown, I would use rectangle graphic objects for the four alarm states and change their back ground colour by inserting an expression condition in the respective rectangle object's background/Fill Colour property.
For example:
If analog_value <20 then red else gray (For Low Low)
If analog_value >20 && <30 then red else gray (For Low)
If analog_value >50 && <60 then red else gray (For High)
If analog_value >70 then red else gray (For High High)
Regards
Rahil
