Address Space - Siemens SIMATIC S7-1500 Manual

Parameters/address space

4.3 Address space

A light pulse with the configured duration takes place within the configured maximum test
time per output channel.
If a light pulse returns a fault, the same light pulse (which means the same bit pattern) is
repeated once after 500 ms. If the fault is still present, the maximum test time is
automatically reduced to 60 seconds and a diagnostic message is generated. If the fault is
no longer present, the output channel is reintegrated after the next fault-free test cycle.
