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.

Multi-core device with separate redundancy schemes in a process control system

A method and system are disclosed for managing Profibus device information in a distributed control system. After receiving input parameter data originating from a Profibus device message, the I/O module assembly performs steps for processing, maintaining and providing the input parameter data to a requesting control processor. The processing step includes extracting input parameter values from a received Profibus device message. The extracted input parameters are then deposited in a repository on the I/O module assembly, such that for a primary input parameter, the I/O module assembly stores at least: () a measured value, and () a status value. Furthermore, the I/O module assembly maintains a reference linking the first status parameter to the first input parameter. The I/O module assembly provides a data status value with the measured value for the first input parameter in accordance with an I/O read operation. The data status value is based on the status value for the first status parameter.
