2.9 Baud rate

Supported baud rates are listed in the GSD file. After power-on or PROFIBUS timeout a baud rate
search is active to detect the current transfer speed on the bus. It is not necessary to set the
baud rate manually.

If the data transmission rate is changed during operation the baud rate search will not be started
by the device. A new power-up or a manual interruption of the PROFIBUS communication is
required to activate the baud rate search in this case.
