A permitted communication partner registration method by which an operation-side communication device that is operated by an operator and a machine-side communication device that is connected to an industrial machine mutually register each other as partners that are permitted to communicate with each other, the method comprising:
- a machine-side communication device identification information reception step in which machine-side communication device identification information that identifies the machine-side communication device is received by the operation-side communication device;
- a first test signal transmission step in which the operation-side communication device wirelessly transmits a first test signal to the machine-side communication device, the first test signal including the received machine-side communication device identification information;
- a first identification information check step in which the machine-side communication device determines whether or not the machine-side communication device identification information included in the received first test signal corresponds to identification information on the machine-side communication device itself;
- a machine-side communication device identification information registration step in which, if the machine-side communication device determines that the machine-side communication device identification information included in the first test signal corresponds to the identification information on the machine-side communication device itself in the first identification information check step, the operation-side communication device registers the received machine-side communication device identification information as identification information on a permitted communication partner;
- an operation-side communication device identification information reception step in which operation-side communication device identification information that identifies the operation-side communication device is received by the machine-side communication device;
- a second test signal transmission step in which the machine-side communication device wirelessly transmits a second test signal to the operation-side communication device, the second test signal including the received operation-side communication device identification information;
- a second identification information check step in which the operation-side communication device determines whether or not the operation-side communication device identification information included in the received second test signal corresponds to identification information on the operation-side communication device itself;
- an operation-side communication device identification information registration step in which, if the operation-side communication device determines that the operation-side communication device identification information included in the second test signal corresponds to the identification information on the operation-side communication device itself in the second identification information check step, the machine-side communication device registers the received operation-side communication device identification information as identification information on a permitted communication partner;
- a first announcement information output step in which, if the machine-side communication device determines that the received machine-side communication device identification information corresponds to the identification information on the machine-side communication device itself in the first identification information check step, a first announcement information is outputted to attract attention to the machine-side communication device;
- a first operation completion signal transmission step in which, if a first operation corresponding to the first announcement information is performed, the machine-side communication device wirelessly transmits a first operation completion signal to the operation-side communication device, the first operation completion signal indicating completion of the first operation;
- a second announcement information output step in which, if the operation-side communication device determines that the received operation-side communication device identification information corresponds to the identification information on the operation-side communication device itself in the second identification information check step, a second announcement information is outputted to attract attention to the operation-side communication device;
- and
- a second operation completion signal transmission step in which, if a second operation corresponding to the second announcement information is performed, the operation-side communication device wirelessly transmits a second operation completion signal to the machine-side communication device, the second operation completion signal indicating completion of the second operation, wherein
- the machine-side communication device identification information registration step is performed after the operation-side communication device receives the first operation completion signal;
- and
- the operation-side communication device identification information registration step is performed after the machine-side communication device receives the second operation completion signal.
