Connect to Devices
Connections/Interconnects
Connecting the Modbus Adapter and other
IT
family products involves using one or more
of the QCPort interconnects. The Modbus Adapter employs two types of connectors—
one is the backplane interconnect and the other is the short run interconnect. These
interconnects provide the QCPort products with both power and communications.
The backplane interconnect fits within the DIN rail and has plugs on it that connect one
module to another module seated on the DIN rail. The backplane interconnect supports
the power and communication for QCPort and is a passive device. The short run
interconnect uses the RJ style connectors that are ordered in standard lengths.
For more information on making interconnects and applying interconnects, refer to the
QCPort
System Install and User Manual

Connections to the QCPort Channels
The Modbus Adapter has two independent QCPort channels: CHA and CHB. CHA has
connections on the backplane (plug) and the RJ12 port closest to the back of the Modbus
Adapter. CHB has two RJ12 connections, the two closest to the front of the Modbus
Adapter.
