<p>PROBLEM TO BE SOLVED: To reduce an unexpected operation of industrial machinery when a wireless communication is interrupted in a system for operating the industrial machinery using the wireless communication.SOLUTION: An industrial machinery system 1 includes a teaching device 3, a relay device 4 and an industrial machinery 5. The teaching device 3 wirelessly transmits to the relay device 4 a teaching signal including a regulation release signal for releasing a regulation of a drive of the industrial machinery 5 or a regulation non-release signal for regulating the drive of the industrial machinery 5 and a drive signal for teaching the drive of the industrial machinery 5. The relay device 4 generates a control signal corresponding to the teaching signal so as to be transmitted to the industrial machinery 5. The relay device 4, upon detection of the interruption of the wireless communication, generates a control signal corresponding to the regulation non-release signal and transmits it to the industrial machinery 5.</p> |
