Connect to a ControlNet Network
The 1768-CNB and 1768-CNBR modules have a network access port (NAP)
available. The most common and easiest way to connect to the network is by
using the a ControlNet tap. Perform the following steps to connect the
module to the network by using a tap.
1. Remove and save the dust caps from the ControlNet network taps.
2. Connect the tap’s straight or right-angle connector to the module’s
BNC connector.
ATTENTION
Do not allow any metal portions of the tap to contact any conductive
material. If you disconnect the tap from the module, place the dust
cap back on the straight or right-angle connector to prevent the
connector from accidentally contacting a metallic grounded surface.
