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
