Modules are compiled in the table to make things simpler.
Module Meaning Example
Module Configuration for digital I/O modules:
A new byte is generated in the
respective process image. The binary
information of the I/O modules is
mapped on the least significant bit of
the byte.
Configuration for analog I/O modules:
Only the user data required for
operating the I/O module are mapped in
the appropriate process image area
(input process image and/or output
process image).

*-Module Configuration for digital I/O modules.
A module opened byte is fulfilled with
binary information of the I/O module.

RA module Configuration of complex, in particular
analog I/O modules. Input and output
information inclusive CONTROL and
STATUS byte is mapped in the
respective process image area. This
way, the register structure of the
respective I/O modules can be accessed
when parameterization is done via
cyclic process data exchange.

PFC module Allocation of the individual I/O module
to the process image of the internal
PLC. The process data is exclusively
available for the PFC user program.
