3.1.2.1 Reaction in the Event of a Fault
If the device detects a faulty signal on a digital output, the affected module output is set to
the safe (de-energized) state using the safety switches.
If a fault in the device occurs, all digital outputs are switched off.
In both cases, the devices activates the FAULT LED.
The error code allows the user to configure additional fault reactions in the user program.
3.1.2.2 Line Control
The digital outputs can be used to detect short-circuits and open-circuits on the inputs, e.g.,
for an EMERGENCY STOP button complying with Cat. 4 in accordance with EN 954-1. To
this end, the outputs are pulsed and connected to the safety-related digital inputs of the
same device, see Chapter
3.1.1. In this case, the digital outputs assume the function of
pulsed outputs.
