s7-1500 and analog signals

[edward.ortiz]

Hello, I am working with a s7-1500 plc and i am reading analog values from 4 different temperature transmitters. A task of mine is to display the average temperature of the transmitters. This is simple and straightforward. The part I am a bit confused is how to create the logic to remove one of the transmitters from the average if it malfunctions or faults or if I want to service a specific transmitter. I would really appreciate some help with this. If you need any more information please let me know.

Count faulted transmiters and divide by 4 - faulted for example.
