Figure 17: Values of the measuring function
NOTE!
• The measuring function is dependent on the parametrized operating modes and func-
tions. This means that objects, which do not result in a shutdown (e.g. blanking, reduced
resolution), are included in the measurement.
• If the receiver is not in synchronous run (e.g. emitter not in operation, safety field com-
pletely blocked, error state,...), the value 255 is output for all measurements.
