Connect the Module to the Network

You can connect the module to the ControlNet network using a tap 
(1786-TPR, 1786-TPS, 1786-TPYR, or 1786-TPYS) or a network access cable 
(1786-CP).

The following figure shows an example ControlNet network using redundant 
media.

WARNING

If you connect or disconnect the communications 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.

TIP

Use the 1786-CP cable for temporary connections, such as 
programming software. For permanent connections, use a tap.
