Abstract
Abstract A system for a remote diagnosis of a numerical control apparatus (CNC), for remotely diagnosing a failure of the CNC. A personal computer is operated by a service engineer and a remote operation command is output to the CNC through a communication line. Diagnosis data of the CNC is selected based on the remote operation command, transferred to the personal computer, and displayed on a display unit, whereby the service engineer can make diagnosis of the cause of the failure at the CNC, based on the diagnosis data displayed.
