International Classification:

G05B015/00

US Classification:

Abstract:

A distributed control system architecture (HSE) provides an open, interoperable solution optimized for integration of distributed control systems and other control devices in a high performance backbone, provides an open, interoperable solution that provides system time synchronization suitable for distributed control applications operable over a high performance backbone, and provides an open, interoperable solution that provides a fault tolerant high performance backbone as well as fault tolerant devices that are connected to the backbone. The distributed control system architecture comprises a High speed Ethernet Field Device Access (HSE FDA) Agent, which maps services of a distributed control system, e.g., a fieldbus System, to and from a standard, commercial off-the-shelf (COTS) Ethernet/Internet component. The distributed control system architecture also comprises a High speed Ethernet System Management Kernel (HSE SMK) that operates to keep a local time, and keeps the difference between the local time and a system time provided by a time server within a value specified by the time sync class. The local time is used to time stamp events so that event messages from devices may be correlated across the system. The distributed control system architecture further comprises a High speed Ethernet Local Area Network Redundancy Entity (HSE LRE) that provides redundancy transparent to the applications running on the system. The HSE LRE of each device periodically transmits a diagnostic message representing its view of the network to the other Devices on the system. Each device uses the diagnostic messages to maintain a Network Status Table (NST), which is used for fault detection and selection from a redundant pair of resources.
