Effect of the supply voltage and the operating mode
The output values of the module are dependent on the supply voltage for the
electronics/sensors and on the operating status of the PLC (CPU of the DP
master).

Supply voltage on/off
A failure of the supply voltage to the electronics/sensors on the ET 200X is always
displayed by the ”ON” LED on the basic module and also entered in the diagnostic
data area of the basic module.
