Transmission Baud Rate and Unit Address
The unit does not require a Baud rate preset because the baud rate of the network will be
automatically recognized while the communication is starting up. All PROFIBUS-DP baud rates
from 9.6 kbit/s to 12 Mbit/s are supported.
Positions 2…7 of the DIL switch select the unit address, value range 3…126. This address
cannot be changed by the master by the Set_Slave_Address service.
Switch position 1 defines the most significant digit of the front thumbwheel switches to be
transmitted as a numeral or a sign (PB306 and PB541 only).
Version providing a sign (option VZ000) require position 1 to be set to “ON”!

DIL switch settings are only read upon initialization. Changes during
normal operation will not be recognized! After change of DIL switch
settings you must therefore cycle the power supply of the unit.
