Abstract:
In order to more accurately detect the relocation of a numerical control device, a numerical control system is provided with: a power line of a three-phase AC power supply; a socket provided at the end of the power line; a numerical control device that is connected to the socket and receives a feed from a power supply via the socket; and a management device that encrypts the content of communications between the socket and the numerical control device connected to the socket, and carries out communication via the power line. The management device, socket, and numerical control device connected to the socket carry out data verification between the socket and the numerical control device connected to the socket (step S3 - step s14).
