Abstract

See full text

Different devices or subsystems, including programmable industrial controllers, are connected to a common network. Each connected device has the capability for autonomous or quasi-autonomous action based on a common pool of information accessible on the network. For example, all or a subset of devices connected to the network may periodically broadcast status data over the shared network medium; status data may include the current state of the controller and/or environmental conditions that the controller monitors.
