Phoenix Contact RFC 460R PN 3TX Profinet controller

Click2Contact

A redundant control system for Profinet can be created with the RFC 460R PN 3TX controller from Phoenix Contact. This makes it possible to reduce system shutdowns and prevent dangerous situations.

Two RFC 460R type Profinet controllers are used to build a fail-safe automation system. One controller controls and manages the process while, in the event of a failure, the second controller is seamlessly activated to perform processes at both the lower and higher levels.

To create redundancy, the user connects both controllers via a fibre-optic synchronisation cable and then programs one of the two controllers. The second PLC is automatically configured for all redundancy functions via AutoSync technology, after which it is automatically started. Both controllers are continuously synchronised.

The redundant controller for Profinet can bridge over distances of up to 80 km between controllers via fibre-optic cables, with an optional pluggable SFP module. A high-resolution display allows for viewing status reports and error message as plain text, and data visualisation is also redundant due to a redundancy-capable OPC server.
