CONNECTION OF DISCRETE SIGNALS STATION

摘要

It handles the connection of the station of discrete signals for logical control and for transmission of discrete signals from and to the technological process. Each station of discrete signals is connectable to the communication circuit, which is connected with the superior system; the communication circuit is always connected with the input and output of each station of discrete signals, while it is at the same time formed by the input and output of the communication interface, whose duplex output is connected with the inner bus, which connects at the same time with the duplex inputs of the diagnostic unit, units of the discrete inputs and units of the discrete outputs. The individual inputs of the units of the discrete inputs are connected with the units of the discrete outputs from the technological process and the individual outputs of the unit of the discrete outputs are connected with the discrete outputs into the technological process.<IMAGE>
