AB Connection Paths

Posted by Peggie Wong on 09/05/2014 11:09 AM

Connections to CompactLogix, ControlLogix, PLC-5, MicroLogix and SLC Allen-Bradley processors through a ControlLogix Gateway requires a connection path. Other devices, such as protocol converters or cell links, also may require a connection path but is not included in this KB.
The path depends on the modules the connection is being routed through and the manual for the modules should be referenced.
But in general:

It must be an even number of values separated by commas.

In Ignition, the first connection point is a ControlLogix Ethernet module such as ENET, ENBT
or EN2T module.


ENET, ENBT and EN2T:
1 = Backplane
2 = Ethernet Port

CNB:
1 = Backplane
2 = ControlNet Port

DHRIO:
1 = Backplane
2 = DH+ Channel A
3 = DH+ Channel B


Example:
To connect to the processor in slot 0, the path is 1,4,2,12,1,0

Where:
1 = Backplane
4 = Slot 4, CNB module
2 = ControlNet Port
12 = CN 12
1 = Backplane
0 = Slot 0 - Processor
