Installing Your ControlNet PLC-5 Processor 1-21
ControlNet Connection
You can connect programming devices to a ControlNet network
through:
• the ControlNet network access cable (1786-CP)
• the ControlNet 1784-PCC1 cable
• a tap on a ControlNet network
Important: Use the 1786-CP cable when connecting a programming
terminal to the network through a NAP. Using a commercially
available RJ-style cable could result in network failure
.
ATTENTION: Do not connect the same
communication card to both the NAP and
a tap on the ControlNet network.

FLEX I/O Adapter
If you connect or disconnect the ControlNet 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.
