Abstract

The ControlNet network is designed to be the central communication architecture for interoperating automation products. It provides fast, deterministic scheduled data transfer for control purposes and unscheduled non–time–critical messaging for configuration and house–keeping on the same network. This is accomplished by partitioning the bandwidth into a scheduled portion that is guaranteed to be delivered within a specified Network Update Time and an unscheduled portion that is essentially the time remaining after the scheduled traffic is handled. A critical user-supplied parameter for ControlNet is the Network Update Time or NUT. In this article, we studied the critical parameter of the ControlNet network when used in a control situation. Simulation results and conclusions are presented.
