ControlNet Network
The ControlNet network is an open, high-speed, deterministic network used for
transmitting time-critical information. It provides real-time control and messaging
services for peer-to-peer communication. As a high-speed link between controllers and
I/O devices, a ControlNet network combines the capabilities of existing Universal
Remote I/O and DH+ networks. You can connect a variety of devices to a ControlNet
network, including personal computers, controllers, operator interface devices, drives,
I/O modules. A ControlNet network combines the functionality of an I/O network and
a peer-to-peer messaging network. This open network provides the performance required
for critical control data, such as I/O updates and controller-tocontroller interlocking.
ControlNet networks also support the transfer of non-critical data, such as program
uploads, downloads, and messaging.
