Devices with their own dedicated power supply can also be connected instead of
contacts. Connect the reference pole of the signal source to the L- reference pole of
the input.
The safety state of an input is indicated by a 0 signal being passed to the user
program logic. If the test routines detect a fault in the digital inputs, a 0-signal is
processed in the user program for the defective channel. When a fault occurs, the
inputs are switched off (0) and the fault LED indicator is activated.
