Chapter 3 Install a ControlNet Coax Media System
Connect Programming Terminals Through the NAP
Use the ControlNet access cable (catalog number 1786-CP) to connect a
programming terminal to any intelligent device (such as a PLC processor, or
adapter) on a ControlNet link through the network access port (NAP).
1. Connect one end of the 1786-CP cable to the NAP on the front of the
ControlNet node.
2. Connect the other end of the 1786-CP cable to the NAP on the
ControlNet communication interface installed in or connected to your
programming terminal.
To avoid connections that could result in network failures, do not use
the 1786-CP cable:
•
to connect your programming device to the ControlNet network in
two ways simultaneously.
•
to connect a scanner or adapter module to a PLC processor.
•
to connect two separate ControlNet network segments.
WARNING
The network access port is intended for temporary
local-programming purposes only and not intended for
permanent connection. If you connect or disconnect the
NAP cable with power applied to 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 nonhazardous
before proceeding.
