ControlNet

High speed plant network communications capabilities with ControlNet

The ControlNet network is a state-of-the-art control network that meets the demands of real-time, high- throughput applications. The ControlNet network combines the functionality of an I/O network and a peer-to-peer network while providing high-speed performance for both functions.

The ControlNet network gives you deterministic, repeatable transfers of all mission-critical control data in addition to supporting transfers of non-time-critical data. The patented media-access method used on the ControlNet network results in deterministic delivery of time-critical (scheduled) data by assigning it a higher priority than non-time-critical (unscheduled) data. As a result, I/O updates and controller-to-controller interlocking always take precedence over program uploads and downloads and messaging.
