8, 16 or 32 bits are applied in the input
process image of the station proxy (fieldbus
coupler) by fitting a slot with these modules.
The bits 2

to 2
7
are assigned with the signal
condition of the physically connected I/O
module. The bits marked green are made
available for the input and / or diagnostics
information of the following module slots.
One byte process data qualifier (IOPS) is
managed in the direction of the I/O controller
in the cyclic PROFINET IO telegram for
these modules.

The fitting of slots with this module enables
the remaining bit locations to be previously
filled with input modules without bytes
opened with star (bit fields) in the input
process image of the station proxy (fieldbus
coupler). The bit locations marked in a light
red color are respectively occupied by
previous slot allocations. One byte process
data qualifier (IOPS) is managed in the
direction of the I/O controller in the cyclic
PROFINET IO telegram for this module.
