Abstract
PURPOSE: To decrease the number of the signal line for the interface between the computer and the process control circuit in the device which collects the data from the process to be controlled and then draws them into the computer, without complicating the device for the signal transfer.
CONSTITUTION: Control circuit 2 which applies the control signal necessary for a series of process actions for the selection, process and conversion of the analog signal plus signal converter circuit 1 which selects 1-channel analog signal among analog input signals P1WPN sent from the plural units of channels and then converts the signal into the digital signal through the process necessary for the analog signal. Through circuit 1, the converted data is given to computer 100 via series-parallel converter circuit 120. Furthermore, the flollowing units are provided to circuit 2: counter 300 and 310 which perform counting with reception of the channel selction command; and reading exclusive memory circuit 330, 340 and 350 which receive the address command via the output of counter 300 and 310 and give the memory contents read out to circuit 1.
