Abstract: A multicore system controls devices in a process control system. A primary control processing device having a primary master core and a primary remote core is configured for controlling communications on a first network among a first plurality of devices. The primary remote core is configured for controlling communications on a second network among a second plurality of devices. A shadow control processing device is coupled to the first and second networks for processing redundant communications among the devices. The shadow control processing device comprises a shadow master core and a shadow remote core. The shadow master core is configured for controlling communications on the first network among the first plurality of devices. The shadow remote core is configured for controlling communications on the second network among the second plurality of devices.
