How to wire the M12, 7/8" plug
Table 3-12 or 3-13 shows you the pin assignment of the M12, 7/8" plug:
Table 3-12 Pin assignment of the M12 plug (PROFIBUS DP)
Pin
1 Power supply + (P5V2)
2 Data line A (RxD / TxD-N)
3 Data reference potential (M5V2)
4 Data line B (RxD / TxD-P)
5 Shielding
Thread Shielding
*
Can only be used for the M12 terminating resistor. It is not permitted to loop the voltage to
the next plug via a 5–wire cable.
