Monitoring device and method of monitoring

A monitoring device for monitoring an operation condition of a machine tool operatively connected to the monitoring device, the monitoring device comprising a processor configured to:

• communicate with the machine tool to acquire event information generated by operation of the machine tool and state information of the machine tool from the machine tool;
• after generation of the event information, and in response to an occurrence of a predetermined change of state of the machine tool corresponding to content indicated by the event information, judge whether or not the content indicated by the event information has been resolved, based on the event information and the state information;
• and
• in response to judging that the content indicated by the event information has not been resolved after the occurrence of the predetermined change of state of the machine tool corresponding to the content indicated by the event information re-notify of the generated event information,
• wherein the predetermined change of state of the machine tool is that automatic operation to automatically perform a processing has been started.

A method of monitoring by which a monitoring device monitors an operation condition of a machine tool operatively connected to the monitoring device, the method including:

• communicating with the machine tool to acquire event information generated by operation of the machine tool and state information of the machine tool from the machine tool;
• after generation of the event information, and in response to an occurrence of a predetermined change of state of the machine tool corresponding to content indicated by the event information, judging whether or not the content indicated by the event information has been resolved, based on the event information and the state information;
• and
• in response to judging that the content indicated by the event information has not been resolved after the occurrence of the predetermined change of state of the machine tool corresponding to the content indicated by the event information, re-notifying of the generated event information,
• wherein the predetermined change of state of the machine tool is that a power source of the machine tool has been switched from OFF to ON.
