The following figure shows the connection of the option board for digital I/O extension
TA5105-4DOT:
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.
Parameteriza- The arrangement of the parameter data is performed with Automation Builder software.

NOTICE!
Risk of damaging the PLC modules!
Overvoltages and short circuits might damage the PLC modules.
– Make sure that all voltage sources (supply voltage and process supply
voltage) are switched off before you begin with operations on the system.
– Never connect any voltages or signals to reserved terminals (marked with
"NC"). Reserved terminals may carry internal voltages.
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.
