The module contains 8 LEDs:

therefore always indicate voltage status at the I/O terminal.
If the combined I/Os are used as outputs, the following should be noted:
The LEDs of combined outputs E/A2…E/A5 only light up when the output
is high and a supply voltage of 24 V is connected to U
ext
.
Mixing the combined inputs/outputs
If combined I/Os are used as inputs in source operation, i.e. with sending devices
which either apply +24 V to the input or are open, the low status of an open input
can be overwritten as high if the corresponding output at the same address is set
in error. However, if the input is shifted to 0 V with a changeover contact and the
corresponding output is set in error, the MOS-FET can be destroyed, as it is not
short circuit protected. For this reason, only positive-switching contacts should be
used.
