The module provides several diagnosis functions, see Diagnosis
The meaning of the LEDs is described in the section State LEDs
I/O configura- The module itself does not store configuration data. It receives its parameterization data from
tion the CPU module during power-up of the system.
Hence, replacing optional modules is possible without any re-parameterization via software.

NOTICE!
Risk of malfunctions in the plant!
Only if L+/M of the CPU is available and the outputs are already configured in
the AB program, the outputs will switch on as soon as the UP/ZP is available.
This must be considered in the application planning.
NOTICE!
Risk of damaging the I/O module!
The outputs are not protected against short circuits and overload.
– Never short-circuit or overload the outputs.
– Never connect the outputs to other voltages.
– Use an external fuse for the outputs.
If the external power supply voltage via UP/ZP terminals fails, the I/O module
loses its configuration data. The whole station has to be switched off and on
again to re-configure the module.
