FIG. 5 is a diagram illustrating an example of event data when a product mounting operation is performed. Referring to FIG. 5, regarding the power measurement work in the power meter, in power measurement, there are an event “start time” having a trigger “timer” and an event “completion time” having a trigger “timer”. appear. Event data as shown in FIG. 5 is recorded for these events.

  Specifically, in response to an event “start time” whose trigger is “timer”, “instrument 5” as instrument data, “device manager A” as human data, “implementer” as position data 4 ”,“ 9:00 ”as time point data, and“ 100 kW ”as state data are recorded as event data. This means that the device manager A has started work at the time 9:00 in the mounting machine 4 where the measuring instrument 5 measures 100 KW. Similarly, for the event “completion time” whose trigger is “timer”, “instrument 5” as instrument data, “device manager A” as human data, and “mounter 4” as position data “9:45” as time data and “200 kW” as status data are recorded as event data. This means that the device manager A has completed the work at the time 9:45 in the mounting machine 4 where the measuring instrument 5 measures 200 KW.

  As for the product mounting operation, a “mounter” event having a trigger “work start” and a “mounter” event having a trigger “work completion” are generated.
