Industrial communication system, industrial instrument, and industrial communication method

An industrial instrument of a plurality of industrial instruments connected in series, comprising:

• a first storage configured to store a first communication setting that is applicable to communication established between the industrial instruments;
• first reception circuitry configured to receive, based on the first communication setting stored in the first storage, a first signal from a second industrial instrument of the industrial instruments that is connected to the industrial instrument;
• a second storage configured to store a second communication setting that is applicable to the communication established between the industrial instruments and that is a predetermined communication setting common to each of the industrial instruments;
• second reception circuitry configured to receive, based on the second communication setting stored in the second storage, a second signal comprising at least a part of the first signal received by the first reception circuitry;
• and
• first processing circuitry and second processing circuitry configured to perform different processes from each other;
• when the first reception circuitry and the second reception circuitry receive identical signals.

An industrial communication method for a first industrial instrument of a plurality of industrial instruments connected in series, comprising:

• storing a first communication setting that is applicable to communication established between the industrial instruments;
• storing a second communication setting that is applicable to the communication established between the industrial instruments and that is a predetermined communication setting common to each of the industrial instruments;
• controlling first reception circuitry located in the first industrial instrument to receive, based on the first communication setting, a first signal from a second industrial instrument that is connected to the first industrial instrument;
• controlling second reception circuitry located in the first industrial instrument to receive, based on the second communication setting, a second signal including at least a part of the first signal received by the first reception circuitry;
• and
• controlling first processing circuitry and second processing circuitry to perform different processes from each other when the first reception circuitry and the second reception circuitry receive identical signals.
