## Abstract

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 permitted to communicate with each other. A communication device receives a partner ID of a partner communication device intended to be registered as a partner. The communication device wirelessly transmits a signal including the partner ID to the partner communication device. The partner communication device determines whether the partner ID included in the received signal corresponds to the ID of the partner communication device itself, and if so, the communication device registers the partner ID as the ID of a permitted communication partner. The above operations are repeated with the communication device and the partner communication device interchanged.
