<p>PURPOSE:To simplify a subsequent check by recording the information on the time when a fault occurs in a terminal controller or when data are collected from a data entry unit, by providing the data collector unit with a clocking method. CONSTITUTION:Data collector unit 4 is provided with display control part 15, printer control part 16, keyboard control part 17, flopy control part 18, data collection part 19, clocking control part 20, AND circuits 21 and 22, and NOT circuits 23 and 24. In the above constitution of unit 4, while unit 4 is collecting data as a substitute for terminal controller 1, a substitute signal is generated by collection part 19 so as to collect data from respective entry units 3-1 to 3-m, which are stored in flopy disc 14 via control part 18. Next, if a fault occurs to terminal controller 1 during the collection of data, control part 20 is changed over to the clock information recording mode and the time is written to disk 14.</p> |
