Connecting to a
ControlNet Network
Connect a ControlNet PLC-5 processor to a ControlNet network via a
tap with a 1-m (39.4-in) drop cable.
Four taps are available from Rockwell Automation:
Important: ControlNet taps contain passive electronics and must be
purchased from Rockwell Automation for the network to
function properly.
After terminating your segments, you connect your node to the
network.
If you connect or disconnect the ControlNet tap cable
with power applied to this processor or the device on
the other end of the cable, an electrical arc can occur.
This could cause an explosion in hazardous location
installations. Be sure that power is removed or the
area is nonhazardous before proceeding.
When used in a Class I, Division 2, hazardous
location, this equipment must be mounted in a
suitable enclosure with proper wiring method that
complies with the governing electrical codes.
