I/O Device Configuration
3.1.3.2

Configuration

The I/O device is configured in accordance with the physical arrangement of
the node (slot oriented).
Module slot 0 contains the fieldbus coupler in its function as station substitute.
It does not deliver any process data itself, but provides the parameters required
to perform overall settings of the I/O device.
Slots 1 to max. 128 reflect the physical arrangement of the I/O modules that
deliver a part of the process and/or diagnostics data. Supply modules without
diagnostics, internal system supply module, field side connection module as
well as separation and end modules are not considered during configuration as
they do not provide any process data and/or diagnostics data.
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.
