The pin assignment for PROFIBUS DP:

Pin Signal PROFIBUS DP Signal

68 FB1 ISO GND

69 FB2 CNTR-P

70 FB3 Rx/Tx+

71 FB4 not connected

It is also strongly recommended to keep the length for the signal lines below 30 mm and to take

EMC aspects into account.

For details about the circuit for the host system see Figure 21: Schematic NRPEB-CCS and

NRPEB-DPS (Part 1) on page 62.
