*1 The baud rate of a ProfiBus-DP network can be specified only when the ProfiBus-DP network is set up using
a configurator (*2).
The baud rate of all ProfiBus-DP slave modules is set with this configurator, and therefore a different baud rate
cannot be set for an individual slave station.
*2 For the ProfiBus-DP configurator, use the configurator recommended for the master unit.
