Mechanical system maintenance method, mechanical system maintenance program, and machine control device

Abstract

The present invention provides a mechanical system maintenance method that enables easy maintenance of a mechanical system without leading to a decrease in security, safety, or production efficiency. This mechanical system maintenance method involves performing, by using a remote device connected to a WAN, maintenance of a mechanical system that includes a machine and a machine control device that controls the machine. The mechanical system maintenance method further involves using the tethering function of a mobile terminal device to connect the machine control device to the WAN, enabling data transfer between the remote device and the machine control device connected via the WAN, and controlling the machine control device by using the remote device.
