ControlLogix ControlNet Interface Module

Publication

1756-IN607A-EN-P - February 2008

Connect the Module to the Network

You can connect the module to the ControlNet network by using a
tap (catalog number 1786-TPR, 1786-TPS, 1786-TPYR, or 1786-TPYS).

This example shows a ControlNet network using redundant media.

1756-CN2R Module
(in 1756-A4 chassis)

ControlNet Node

ControlNet Link

ControlNet Node

Redundant Media
(optional)

For network connections, we recommend taps with a straight
connector (catalog number 1786-TPS or 1786-TPYS) because of the
location of the BNC connectors on the bottom of the module.

WARNING

If you connect or disconnect the communication cable with power
applied to this module or any device on the network, an electrical arc
can occur. This could cause an explosion in hazardous location
installations.

IMPORTANT
