ControlNet™ Network
Overview
Providing Users with a Robust, Deterministic, and Secure I/O Network for Their Most Challenging Applications
The ControlNet network is an open, state-of-the-art control network that meets the demands of real-time, high-throughput applications. The ControlNet network uses the proven Common Industrial Protocol (CIP) to combine the functionality of an I/O network and a peer-to-peer network 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. I/O updates and controller-to-controller interlocking always take precedence over program uploads and downloads and messaging.
ControlNet Features
- Programming, processor-to processor interlocking, and I/O control on the same link without impacting time-critical I/O
- Media options to fit your application needs including copper, fiber, fiber ring, media redundancy, and intrinsically-safe
- Improves I/O performance and controller-to-controller interlocking with high-speed data throughput
- Supports a maximum of 99 nodes, with no minimum distance between nodes
- Simple and flexible installation options available
- Access the network from any node for PLC processor programming and troubleshooting
- Improved network efficiency with Multicast of inputs and peer-to-peer data
- Deterministic, repeatable transfers of data to/from digital and analog I/ O
- Producer / Consumer services let you configure devices, control, andcollect information over a single network
