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.

(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.
