<p>An unmanned diagnostic communications system for analyzing the operation of a remotely situated computer controlled machine tool and for diagnosing any abnormalities disclosed during machine tool operation includes an auto dialer and MODEM coupled between the computer controlled machine tool and one end of a communications channel and an auto answer MODEM coupled between the other end of the communications channel and a diagnostic computer. In response to a test command entered by an operator to the remotely situated computer controlled machine tool, the auto dialer automatically establishes a communications link with the diagnostic computer through the auto answer MODEM. Thereafter, the diagnostic computer determines the identity of the remotely situated computer controlled machine and then transmits instructions to the computer controlled machine tool to direct its operation. In accordance with the program instructions from the diagnostic computer, the computer controlled machine tool transmits data indicative of machine tool operating characteristics to the diagnosing computer which is then analyzed by such data to detect and diagnose any machine tool abnormalities.</p> |
