Format of the Parameter Telegram

This section provides a detailed description of the format of the parameters for the
Profibus NIU and the input and output modules. This may be useful when setting
parameters using acyclic services or if there is no interface for the simple selection
of parameters. One possible application is changing the parameters of failsafe
values during operation.
Parameterization in data exchange mode is not permitted for the configuration
data (measuring range, sensor type, etc.).
The data for the configuration and the failsafe value can be found in the module
datasheets.
