PURPOSE:To monitor the working status of an industrial machine at hour/minute units by discriminating the working state of the industrial machine based on a working signal to discriminate the working state of the industrial machine, storing the discriminated result of it in a memory means as working discriminating information and transmitting the working discriminating information within the memory means corresponding to a requirement from a working time summing-up circuit. CONSTITUTION:When an industrial machine works, a working state is discriminated based on a working signal ES from a working signal generating means 3 and the result of it is stored in a memory means 6 in time series as working discriminating information. When the working time of the industrial machine is summed up after a constant period passes, a working time summing-up circuit 2 is connected to a monitor circuit 1 through a communication cable and the period to be monitored of the working time is inputted by an input means. Accordingly, stored data within the memory means 6 are transmitted to the working time summing-up circuit 2 through a communication cable. Thus, since an arithmetic processing circuit 13 of the working time summing-up circuit 2 sums up the working time within the period set by the input means based on the information from the monitor circuit 1, a working status is monitored at the hour/minute units. |
