Setting the PROFIBUS DP address at the connection module and activating the terminating resistor
1. Remove the cap from the connection module.
2. Set the PROFIBUS DP address using the DIP switches (see the example below).
3. If this ET 200pro is the last node on PROFIBUS DP, enable the terminating resistor using
the DIP switch.
Note
Enable the terminating resistor to terminate the PROFIBUS DP network at this end point.
4. Screw the cap back into the connection module.
5. Hand-tighten the cap (minimum tightening torque 1.0 Nm).
