1. Communication wiring
The method to connect a PROFIBUS DP detected cable and a GW unit PROFIBUS DP communication
connector is shown below.
Connecting cable
•Make sure to connect the signal cables to designated pins (Refer to Fig. 1).
•Be sure to connect a "Terminating resistor" to both
ends of transmission line. (Refer to Fig. 2).
Tighten the connector securely to 0.5 to 0.6 Nm
tightening torque.
Connecting terminating resistor
•Be sure to connect a terminating resistor to both ends of transmission line (Refer to Fig. 3).
Tighten the connector securely to 0.5 to 0.6 Nm tightening torque.
•The terminating resistor to be used differs depending on the specification of the cable.
The following terminal resistance value is based on the specification of type A cable.
