Configuring Digital I/O Modules - WAGO -I/O-SYSTEM 750 Technical Description, Installation And Configuration

For each I/O module, up to 8 configuration modules are available in the
hardware catalog. The modules are designated by their item number followed
by the number of signal channels, e.g. 75x-467 2AE. Additional information is
included in the module description as different configuration possibilities are
available (see below).
3.1.3.2.1

Configuring Digital I/O Modules

Four digital I/O modules with a granularity smaller or equal to 8 bits are listed
in the I/O device hardware catalog. Three modules reserve 1, 2 or 4 bytes in
the respective area, one of them is used to fill the reserved areas. The 2- and 4-
byte modules can be found in the hardware catalog under the sub-category
"Word / double word module". With configuration modules that require more
process image memory than the level of existing information of the respective
I/O modules, the amount of bit information, which is still available in the
allocated area, is indicated in brackets with a positive sign.
The item numbers of the modules, that do not provide a process image
memory but are used to fill previously excessively reserved bit information,
are marked with a star (*). Furthermore, the module names, that are
represented with a negative sign in brackets, contain the amount of
information that has been previously allocated in the area of the process image
by the I/O module.

Description
Configuration module for 32 digital inputs,
4 bytes are reserved in the input process
image of the I/O controller. The bit
information in the first byte is allocated to
the input data of the configured I/O module
according to the number of existing signal
channels. Remaining bit locations (shown
with a positive sign in brackets) can be
allocated to the signal states of the
following I/O modules having the same
type of signal. This is done by configuring
the DI_0 modules of the relevant I/O
modules.
Configuration module for 16 digital inputs,
2 bytes are reserved in the input process
image of the I/O controller. The bit
information in the first byte is allocated to
the input data of the configured I/O module
according to the number of existing signal
channels. Remaining bit locations (shown
with a positive sign in brackets) can be
allocated to the signal states of the
following I/O modules having the same
type of signal. This is done by configuring
the DI_0 modules of the relevant I/O
modules.
