Setting the PROFIBUS DP address
Configurable PROFIBUS DP addresses are 1 to 99.
Proceed as follows to configure the PROFIBUS DP address:
1. Remove the two M12 sealing caps from the rotary coding switches
(use 14 mm socket wrench, if needed).
2. Configure the desired PROFIBUS DP address with a screwdriver on the rotary coding
switches.
– Top rotary coding switch: Tens digit
– Bottom rotary coding switch: Ones digit
3. Screw the two M12 sealing caps back onto the thread to protect the rotary coding switches
(torque: 0.5 to 0.8 Nm).
4. Switch the supply voltage off and on again (POWER OFF/POWER ON).
The figure below shows the rotary coding switches for configuring the PROFIBUS DP address.
