KEPServerEX - Allen-Bradley ControlLogix Routing Examples

The concept behind routing is to provide a means of communicating with a remote device over various networks. Routing can be thought of as a bridge between your local device and a remote device even if they are on two different field bus networks. Access to a remote (destination) back plane allows for direct communication with the following modules located on this back plane

Networks Supported:

ControlNet
DH+
TCP/IP (EtherNet/IP)

Remote Modules Accessible Via Routing:

ControlLogix 5500 processor for ControlLogix applications
SoftLogix 5800 processor for SoftLogix applications
1756-DHRIO interface module for DH+ Gateway applications
1756-CNB or 1756-CNBR interface module for ControlNet Gateway applications
