The baud rate of the PROFIBUS is common for all bus devices. Changing the
baud rate has the consequence that all other parameters will be re-calculated.
The System Configurator checks if the baud rate is supported by all configured
devices
on basis of the entries in the GSD file .
If the System Configurator finds at least one device in the configuration that does
not support the selected baud rate, an error message appears. Some parameters
can be changed individually by opening the Edit Bus Parameter dialog box. Use
the Edit button to look at the actual parameters.
Note that if any changes are made in the bus parameters, the parameter for the
field
Optimize must be changed from standard to by user .
Caution: Changing the bus parameter individually can force a communication break.
The Highest Station Address is the highest bus address up to which the master
will search for other active master stations to pass the send permission. This
value should not be set below the master address.

The current version of PROLINX SyCon does not allow changing of DP-Master
settings. These are the default parameters:
