Baud Rate Configuration and Device Address
During the startup of the CLIC-02/PBUS the identification of the Baud Rate and the Profibus

by CLIC-02/PBUS, which ranges between 9.6 kbits and 6 kbits. Each slave must have a
different ID, from 0 to 126. The CLIC-02/PBUS ID is adjusted by the switches SW1, as
