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)

In a nuclear process control system, a priority logic module (PLM) is provided. The priority logic module comprises a plurality of input ports, each input port associated with one of a plurality of priorities, a plurality of output ports, and a test mode select port associated with a test mode select signal. The test mode select signal selects one of a normal mode or test mode, each mode being associated with matching signals received by the input ports to signals sent by the output ports. The priority logic module further comprises a configurable priority logic circuit, wherein the priority logic circuit maps one of the input ports to one of the output ports.
