Interface ControlLogix and your control system OPC server with RoviSys ControlLogix Universal Gateway

RoviSys ControlLogix Universal Gateway (CU-Gate) enables you to establish a real time bi-directional interface between Allen Bradley ControlLogix® processors and any other control system with an OPC server. CU-Gate supports exchange of process data and supervisory control information between two separate systems.

With CU-Gate, you have a straightforward and efficient means of migrating to new systems and allowing existing older systems communicate with new ones. It efficiently integrates with any OPC server and does not have any capability limitations.

CU-Gate interfaces tags from your OPC server directly and securely to ControlLogix over the backplane, eliminating the need for a ControlLogix OPC server or bridge.

Discover the possibilities

Because it is an open solution without arbitrary tag or capability limits, with CU-Gate you have practically no limits on what and how you can connect systems and devices to ControlLogix processors. You can create ControlLogix interfaces with distributed control systems, PLCs and single loop controllers.

Secure and low maintenance

CU-Gate can host your OPC server with an in-chassis Windows PC and communicates directly and securely across the ControlLogix backplane. This eliminates the need to manage desktop OPC servers and Ethernet connections from OPC servers to ControlLogix PACs.

Possible migrations to ControlLogix from legacy control systems using CU-Gate include the systems listed here. You can also use CU-Gate to interface to any other system with a native or third party OPC server including field devices, Foundation Fieldbus, Profibus and building systems for high availability HVAC data centers, campuses and more.
