Title: WORK DEVICE AND TIME MEASUREMENT METHOD FOR WORK DEVICE
Abstract:
When a plurality of individual work devices that execute a series of tasks were integrally controlled by an integrated control device, it was difficult to analyze logs among the plurality of individual work devices. One of four individual work devices 12 transmits a time inquiry signal S to a main integrated control device 72 through a serial communication cable 86. The main integrated control device 72 issues a time at a time point T at which the time inquiry signal S was received, as a response to one of the four individual work devices 12 that transmitted the time inquiry signal S. The one of the four individual work devices 12 receives the response from the main integrated control device 72 at a time point T1, adds a communication time to the time at the time point T, and calculates the time at the time point T1. One of the four individual work devices 12 starts operation of the in-device time, with the time at the calculated time point T1 as the starting point. In addition, one of the four individual work devices 12 records a log on the basis of the in-device time.
