Abstract: A new and improved control system architecture using a combination of standard function blocks and new flexible function blocks eliminates the need for expensive and difficult to maintain custom control software and special I/O gateways for discrete/hybrid/batch and PLC applications. The end user builds application-specific flexible function blocks by configuring the number and type of inputs and outputs, and the block algorithm. Flexible function blocks and gateway flexible function block interconnect and interoperate with each other and with standard function blocks in a distributed control architecture.

Abstract: An apparatus, system and process is provided for communicating safety-related data, over an open system, from a sender to a receiver. Safety-related components, including function blocks, flexible function blocks, resource blocks and transducer blocks, as well as, safety-related objects are provided. Also, an extended safety-related protocol provides for authenticating communications between safety-related components over an existing black channel, such as one using a fieldbus Architecture.

Abstract: A new and improved control system architecture with a single server interface for application software that eliminates manual intervention by providing online, immediate access to information needed for plant/enterprise optimization, operation, configuration, maintenance and diagnostic application software. The control system architecture provides a method of dynamically creating a server directory to enable automatic access in an integrated control system. The method includes accessing a live list of fieldbus devices, building/updating a browse tree structure, the browse tree structure defining a branch and leaf node organization and naming for and data from the fieldbus devices, copying AP directories and FF objects from active fieldbus devices into a FF directory and mapping the FF Directory into the server directory.

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.
