Abstract
PURPOSE: To reduce the cost of a circuit with the constitution simplified by dividing the time zone into two parts by a control signal and by sending the kind of transmitting data and an operation instruction to a terminal in the 1st time zone while sending the data itself in the 2nd time zone.
CONSTITUTION: In control-system center 10, center procesor 100 controlling several terminal equipments on the basis of a preset program and transmission controller 300 are installed. Further, in plural terminal devices 11W18, terminal control device 400 and input/output device 500 are provided, and line (l1 )for transmitting synchronizing clock signal CLK of transmission-reception data is provided between units 300 and 400 provided to each of terminal equipments 11 to 18. In addition, line (l2 )for signal CTL transmission consisting of the 1st and 2nd time zones with the transmission time of a control data signal specified, transmission data transmission line (l3 ),and reception data transmission line (l4) are also provided. In the above constitution, data to be transmitted to units 11 to 18 are assigned to the 1st and 2nd time zones to simplify the unit and also to improve the transmission efficiency.
