Method and apparatus for synchronizing configuration changes across multiple components of an industrial control system

摘要

An industrial control system includes an industrial controller and a series of bridge devices logically connected in a cascaded arrangement to facilitate data communication between the industrial controller and an I/O device. The control system further includes a programming interface connected to the industrial controller to provide modifications to the program and component configuration. Modifications are provided to the controller and to the bridge devices across the network in a multiphase operation that includes a first operation that cascades the modifications from the industrial controller and to the bridge devices, and a second operation that cascades a apply command to the industrial controller and to the bridge devices instructing the industrial controller and the bridge devices to update the configuration of each of the devices based on the modifications provided in the first phase only upon acknowledgement that the industrial controller and each of the bridge devices has accepted the modifications.
