3.5.2 Displaying data in PROFIBUS-DP

Any standard PROFIBUS-DP master can exchange data with the interface module. Even very "simple"
master interfaces can be used thanks to the data structure.

3.5.2.1 Parameterization

The interface module does not support any user-specific parameter data in the PROFIBUS-DP
parameter message.

3.5.2.2 Configuration

Two configurations can be used for operating the interface module, both with 12 bytes but in one case
with data integrity over the entire length and in the other without data integrity. The configuration with
data integrity must be used for this program as messages can otherwise be corrupted. Configuration
without data integrity is only available for use by the cyclical data of the message.
