Title:

プロセス制御ネットワーク内における通信のためのプロセス制御システム、及びプロセス制御システムの障害検出方法

Document Type and Number:

Japanese Patent JP4786673

Kind Code:

B2

Abstract:

A process control system is provided having a plurality of I/O devices in communication using a bus. A primary redundant I/O device and a secondary redundant I/O device are coupled to the bus, where the secondary redundant I/O device is programmed to detect a primary redundant I/O device fault. The secondary redundant I/O device, upon detecting the primary redundant I/O device fault, publishes a primary redundant I/O device fault message on the bus. The controller may deactivate the primary redundant I/O device and activate the secondary redundant I/O device responsive to the primary redundant I/O device fault message.
