Redundant application stations for process controlsystems |
摘要 |
An application station for use in a process control system includes a redundancy manager and a redundancy link subsystem coupled to the redundancy manager. The redundancy manager is adapted to communicate with a second application station via a redundancy communication link. The redundancy manager establishes a redundancy context with the second application station and uses the redundancy context to track the operations of the second application station. Additionally, the redundancy manager receives information from the second application station via the redundancy link and the redundancy link subsystem and, in response to the information, executes a switchover of the operations of the second application station to the application station. |
