The industrial communication networks are the infrastructures to connect the bottom field devices and control devices in the factory, which realize the interconnection and interoperability of intelligent manufacturing. Its communication quality is a prerequisite to ensure the normal operation and production in the factory. According to the layered functions of industrial communication network protocol, this paper establishes a communication quality indicator system, consisting of physical layer waveform characteristic indicators and time characteristic indicators, data link layer performance indicators and function indicators, and application layer behavior related indicators. The general process of industrial field communication quality diagnosis and evaluation is proposed. Through the detection of industrial communication quality indicator parameters, the possible problems in the field can be diagnosed and evaluated, thus the rapid location of communication anomalies or faults in the industrial field can be achieved.
