WAGO -I/O-SYSTEM 750 Technical Description page 169

These modules present themselves with 2x2 bytes, so that the object 0x6401
(also 0x2400 possible) for 2 byte Special Modules, Inputs is used. Therefore
for each module two Subindices are occupied
SSI Transmitter Interface modules with Standard Data Format
750-630/000-004, -005, -007
The above SSI Transmitter Interface modules with Standard Data Format have
a total of 5 bytes of user data in the Input Process Image (4 bytes of user data
and 1 byte of status). The following table illustrates the Input Process Image,
which has a total of 6 bytes mapped into the image.
These modules present themselves with 1x6 bytes, so that the object 0x3200
for 6 byte Special Modules, Inputs is used. Therefore for each module one
Subindex is occupied
Incremental Encor Interface Modules
750-631
The above Incremental Encor Interface modules have 5 bytes of input data and
3 bytes of output data. The following tables illustrate the Input and Output
Process Image, which have 6 bytes mapped into each image.
