A method is disclosed for using an alternate communication path to send and receive data between a first network node and a second network node. The method includes establishing a first communication path between the first network node and the second network node that sends and receives data between the first network node and second network node and a second communication path between the first network node and the second network node that sends and receives data between the first network node and second network node. A diagnostic program tests the first and second communication paths for network failures causing the alternate network path to send and receive data between the first network node and second network node when a network failure in the first and second communication paths is detected and alerting a technician of the failure and that the first and second communication paths need repair. The first and second communication paths returning to normal operation upon the repair of the failure.

Method and apparatus for an alternate communication path for connected networks

A method for use by a primary device associated with a secondary device of a redundant pair, the primary device issuing a synchronization request to its control database causing the primary device to send a tracked memory file storage of the primary device to the secondary device to update the secondary device control database and to periodically send on request of the primary device the cached changes made in the primary device to the secondary device to update the secondary device control database. The secondary device using the updated control database to identify communications connections and paths to I/O modules and peer devices assigned to the secondary device and to perform diagnostic testing of the communications connections and paths identified by the interrogation and send diagnostic messages upon detection of faults in the communication connections and paths identified.

Method and apparatus for the enhanced diagnostic coverage of a secondary device of a redundant controller pair

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.

Redundant controllers or input-output gateways without dedicated hardware

A apparatus having a control network and a first controller comprising a microprocessor configured to support communication functions, control execution functions, I/O functions, and control network interface functions, a second controller configured as a redundant partner to the first controller, and an I/O link and I/O modules.

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.

On-process migration of controller(s) to utilize an IO pool

An apparatus is disclosed that is used in an industrial process control and automation system that operates using an open platform data communication protocol.
