Abstract: An apparatus includes a first interface configured to communicate over a first industrial process control network using a first protocol. The apparatus also includes a second interface configured to communicate over a second industrial process control network using a second protocol. The apparatus further includes a third interface configured to communicate with at least one supervisory device over a third network. In addition, the apparatus includes at least one processing device configured to provide concurrent access for the at least one supervisory device to process control devices coupled to the first and second industrial process control networks during a migration of process control devices that use the first protocol to process control devices that use the second protocol.

Abstract: An electronic device and other electronic device include a first and second port that utilizes a parallel redundancy protocol in a communications network including a first and second lane. The devices include a processing circuit, a PRP handler, a protocol stack, a memory, permanent storage accessible by the processing circuit, and transmit and receive circuitry for transmitting and receiving packets. A redundancy manager is for identifying path faults in the network. The processing circuit implements a method of detecting network path fault, including the other electronic device transmitting a frame pair over the first lane and second lane. The electronic device receives the frame pair and implements a receive processing flow, when the first frame or the second frame is identified to be a redundant frame, removes the redundant frame, and compares a first frame parameter to a second frame parameter to determine when the path fault is present.
