    CompactLogix ControlNet Interface Module 

Publication

 1768-IN006A-EN-P - September 2007

Connecting a Desktop Computer Directly to the ControlNet Network

A 1786-TPR, 1786-TPS, 1786-TPYR, or 1786-TPYS cable can be connected 
from a desktop computer with either a 1784-PCIC or 1784-PCICS card 
directly to an existing ControlNet network. A desktop computer connected 
through this cable is counted as a node and must have a unique network 
address (MAC ID) less than or equal to the maximum unscheduled node 
(UMAX).

When connecting the module to a ControlNet network, you should also refer 
to the following documentation:

•

ControlNet Coax Taps Installation Instructions, publication 
1786-IN007

•

ControlNet Coax Media System Planning and Installation Manual, 
publication CNET-IN002

TIP

For network connections, we recommend taps with a straight 
connector (catalog number 1786-TPS or 1786-TPYS) because of the 
location of the BNC connectors on the bottom of the module.

ATTENTION

If a SoftLogix5800 processor is running on the computer containing 
the 1784-PCIC or 1784-PCICS card, do not use the 1786-CP cable to 
connect the card to the ControlNet network. Instead, connect the 
card directly to the ControlNet network.
