Interface modules
12.1 Interface modules for PROFIBUS DP
Pin assignment of PROFIBUS DP and voltage supplies on the CM IM DP M12, 7/8" connection
module

* The voltage may only be used to supply the external terminating resistor. The voltage must not be
looped through to the next connector with a cable.
** We recommend that you connect the functional earth via the M12 thread (because it has a larger
surface area than terminal 5).
