A fault tolerant control system delivers an embedded functional safety core and a distributed control engine with an onboard communication link in an industrial process control environment. The fault tolerant control system includes a process control workstation connected to a first network and a fault tolerant safety controller connected to a second network, wherein a process controller module, a safety controller module and a field device system integration module are co-located on a power interface board.

Unified communications module (UCM)

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, a time synchronization monitor is provided for monitoring timing distributions and determining when such distributions have drifted beyond an acceptable limit.

System and method for implementing time synchronization monitoring and detection in a safety instrumented system

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.

System and method for implementing safety instrumented systems in a fieldbus architecture

A control system for executing an application program is disclosed herein. The control system includes a plurality of main processor modules. The control system further includes a plurality of input/output modules for providing input process data to associated ones of the plurality of main processor modules. A voting system is operative to compare the input process data associated with first and second of the plurality of main processor modules to the input process data associated with a third of the main processor modules. This results in generation of voted input process data utilized by the third main processor module in executing the application program. In certain implementations the system includes a high-speed bus for distributing the voted input process data to the first and second main processor modules, each of which also executes the application program based upon the voted input process data.
