Patent ID: 10868745

Abstract:
A self-checking network device (201) for communication in a real-time network, wherein the self-checking network device (201) includes at least four modules (S-COM, P-COM, P-MON, S-MON), wherein the network device (201) and/or each of the four modules is configured such that a first module (S-COM) of the at least four modules receives both regular data and protocol data from said communication links (110) on a first input (COM-IN), and said first module (S-COM) forwards protocol data on a second input (P-COM-IN) to a second module (P-COM) of the at least four modules, wherein said second module (P-COM) executes a first function (C-PU) as part of the one or the more of the network protocols using protocol data received on said second input (P-COM-IN) and produces protocol data as output on a first output (P-COM-OUT).
