Configuration and Parameterization of the I/O Modules
5.4.5 Serial Interfaces
All serial interface modules have 2 bytes of extended parameter information,
which serves for the identification on the internal bus and the structure of the
mapping table. Two further bytes follow which are reserved for future options.

Meaning
The I/O module process data is
- supplied by the I/O module or
supplied to the I/O module
ignored by the coupler
The diagnostics information of the correspond-
ing channel is
- transmitted to PROFIBUS DP master
- not transmitted to PROFIBUS DP master
