5.7.1 PROFIBUS DP interface (NHST-T100-DP/DPM)
The PROFIBUS DP interface at X3 is a RS-485 interface according to
PROFIBUS standard EN 50170.
PROFIBUS Pin Signal Description
9-pole sub-D
socket, female
3 Rx/Tx + Receive- / Transmit data positive
4 CNTR-P Control signal for repeater (direction control)
5 ISO GND Data ground
6 VP Power supply positive 5V for terminating
resistor. Maximum current 100 mA.
8 Rx/Tx ‑ Receive- / Transmit data negative

Table 25: PROFIBUS RS-485 pin assignment
A pull up resistor of 100 kΩ is connected inside the device at “Rx / Tx +“.
A pull down resistor of 100 kΩ is connected inside the device at “Rx / Tx -“.
5.7.2 CANopen interface (NHST-T100-CO/COM)
The CANopen interface at X3 is an ISO 11898 interface according to the
CANopen CiA DS 102 standard.
CANopen Pin Signal Description
9-pole
sub-D male
2 CAN L CAN Low bus line
3 ISO GND CAN ground
7 CAN H CAN High bus line
1, 4, 5,
6, 8, 9 Important note and strongly recommended:
Leave these pins unconnected! Otherwise there
is a high risk of a device damage.
