2.4.5 Explanation of settable configuration values
Busaddress
The valid PROFIBUS address range is from 0 to 125. The module has two
rotating address switches to set the network address from 0 to 99.
With the rotating switches, however, you are not able to select bus addresses
above 99. If you choose 0 on the address switches, then the module will take the
address parameter from the configuration data array. Now you are able to setup
bus addresses above 99.

Force User Configuration
If the parameter ForceUserConfiguration is set to 1, the slave will not start its
network communication until master and slave configuration do not matches
each other. If this value is set to 0 the slave accepts the configuration sent from
the master, unless the master and slave configuration match.
Watchdog Timeout
The Slave module supervises its I/O exchange with the controller with a timeout.
If the controller does not update the output data within this time, the Slave stops
the cyclic data exchange to the master and goes into a safe state.
