Modbus Plus Communication Connection
Communication between a VS-616G5 drive and the MB+ network requires a physical connection
from your drive to the MB+ network. Connect your network communication cable into P1 (9-pin
“D” shell) on the MB+ board. Modicon offers cables and connectors for the MB+ network.
Modicon Modbus Plus Wiring:
The recommended cable for MB+ network connections is Belden 9841. This cable consists of:
??
One twisted signal pair: blue/white
??
Drain wire: bare
??
Overall aluminized mylar shield
This cable is available from Modicon as the following part numbers:
??
97-9841-100 MBPlus 100 Foot Reel

Two types of connectors are available from Modicon for connecting devices to the network. Each
in-line drop requires an in-line connector. The two drops at the ends of the Modbus Plus network
cable each require a terminating connector. When the terminating connectors are installed on the
two extreme ends of the cable, no other termination is required.

Route the Modbus Plus cable out of the bottom of the drive enclosure. Select a cable routing
method to protect the cable from physical damage and potential electrical interference sources.
Note: Avoid sources of electrical interference capable of inducing noise into the cable.
If a cable must cross power wiring, it must cross only at a right angle.
