Claims

To transfer to the executive points of the address, a group of channels is produced by converting it with the help of Encoder 2 into a parallel binary code. The signals of this code with the help of linear amplifiers of the address 3 are transmitted over the address wires and the communication line to the executive points. The transmission time of the code is limited by the signal “address transmission. The transmitted code combination is received at one of the execution points by the address decoder 8, the output signal of which ensures the selection of a group of TU channels. The control signals D-triggers Yu of the selected item are transferred to the state corresponding to the transmitted control commands. The transmission time of control commands to the group is determined by the speed of the receive D-flip-flops, after which the data wires are released to transmit the signals of the state of the mechanisms. After the end of the transmission of the address signals, a short pulse appears at the output of differentiating element 11 of the selected channel group. This impulse provides, by means of the AND 12 logic elements, signal transmission of the state of a group of actuators. At the control point, the signals are amplified by amplifiers 7 and fed to the inputs of D-flip-flops 5. Information is received in the channel memory cells only for this group of flip-flops, the clocking C-inputs of which are affected by the group address signals and the strobe pulse. Information exchange on other groups of channels is similar.
