Abstract:
1. A dedicated independent diagnostic access device for effecting network health performing quality checks of a process control system network communication diagnostic data through combining diagnostic data packet analysis, including protocol, process, and environmental data, network communication diagnostics analyzing data packets' emerging statistics to provide “early warnings” to facilitate adding or subtracting network communication functionality and reconfiguring of intelligent network field devices commonly coupled to a network, comprising: a data network connection for receiving and transmitting network communication diagnostic data from network packet analysis, a process control network connection for receiving and transmitting process control network diagnostic data packets, a power connection, a processor, a network packet analysis operational software program, a network packet analysis user software program, a network packet analysis user interface; and the processor operating on the process control network diagnostic data packets with the operational software, characterizing data diagnostics and quality, communicating network packet diagnostic data to operators through the user interface and/or through the data network.
