TIP
Connect to a Device on the ControlNet Network
The 1786-CP cable (Figure 2) connects a host computer to another ControlNet
device. It has two RJ-45 8-pin connectors.
Figure 2 1786-CP cable
Do not connect more than one ControlNet network to this
card. If you attempt to connect a second network to this
card, your communication system will operate erratically.
If you connect or disconnect the ControlNet cable with
power applied to the module or any device on the network,
an electrical arc can occur. This could cause an explosion in
hazardous location installations. Be sure that power is
removed, or the area is non-hazardous before proceeding.
If you use a non-redundant cable system, all ControlNet
devices must be on the same channel, channel A.
