Digital input/output modules
Configuration and programming of the digital inputs/
outputs
The module has 16 connections. The first 12 connections (0 to 11)
can be used as inputs and outputs, the connections 12 to 15 can
only be used as inputs,
a
figure 49.
The configuration of the module is performed in the "PLC Confi-
guration" register. An "Empty slot" is inserted with
"Set element". The following appears, for example:

Important!
The operating voltages for the inputs and outputs must
come from the same source as those for the module.
