PURPOSE:To improve the control finish speed, by using two-motion about the operation from a control desk, and using one-motion about the operation from a computer, as simultaneous transmission of a selection signal and an on/off signal to a slave station. CONSTITUTION:A selection end signal is given from a decoder 24 to an input circuit 26 and transmitted to a master station as one-bit information. The master station draws this signal from a memory 19 to form the two-motion system of ''selection'' and ''operation'' by releasing the transmitted interlock of the input control with this signal. A selection end signal, 1-bit is picked up from the memory 19 at a selection end pickup circuit 28, this signal is outputted as the interlock information of a transmission gate 14 and used for the interlock release of the control signal (on/off). That is, the device selection signal is transmitted to a slave station, and while the return signal (selection end signal) from the slave station is not confirmed, no control signal is transmitted as the two-motion system. |
