    Abstract: A process control system (PCS) includes a cable connection including physical cables including a first cable for connecting between a process controller and an I/O access device, and an independent second cable for connecting the process controller and a second node being the I/O access device or another device. The I/O access device is for coupling to I/O module(s) to receive an output of the I/O access device. An output of the I/O module is coupled to a field device coupled to processing equipment. The process controller and I/O access device each include a processor and memory that implement send and receive logic for communicating using any of multiple redundancy protocols including a first and a second redundant protocol. The cable connection is for supporting simultaneously communicating between the process controller and the second node utilizing both the first redundant protocol and the second redundant protocol.

    Abstract: A method of fault-tolerant process control includes providing a network process control system in an industrial processing facility (IPF) including a plant-wide network coupling a server to computing platforms each including computing hardware and memory hosting a software application for simultaneously supporting a process controller and another process controller or an I/O gateway. The computing platforms are coupled together by a private path redundancy network for providing a hardware resource pool. At least some of the computing platforms are directly coupled by an I/O mesh network to a plurality of I/O devices to field devices that are coupled to processing equipment. Upon detecting at least one failing device in the hardware resource pool, over the private path redundancy network a backup is placed into service for the failing device from the another process controller or I/O gateway that is at another of the computing platforms in the hardware resource pool.

    Abstract: A process control system includes a first process controller coupled to a first set of input/output (I/O) modules that provided first channels, including an I/O software agent coupled to an I/O module pool that includes a first and at least a second I/O module collectively providing pooled channels. The first channels and the pooled channels are each coupled by a respective field device to first and second processing equipment, respectively. The I/O software agent is configured for enabling addition of the first set of I/O modules to the LO module pool, coupling of a plurality of additional process controllers in a controller pool to the first process controller, and enabling at least one of i) making any of the first channels available to any of the process controllers in the controller pool, and ii) making any of the pooled channels available to the first process controller.

    Abstract: A process control system includes first type and second type controllers having different hardware architectures coupled together by a redundancy network for providing a controller pool. Primary application modules (AMs) are coupled to the controller platforms by a plant-wide network. The controller platforms are coupled by an input/output (I/O) mesh network to I/O devices to provide an I/O pool coupled to field devices coupled to processing equipment. A translating device translates states and values from one of the primary AMs running on a first type controller to generate a backup AM having an instruction set compatible with the second type controller. A controller application module orchestrator (CAMO) extends synchronization to the second type controller, makes the backup AM available to the second type controller, and then switches to utilize the second type controller as an active controller running the process.
