Abstract

PURPOSE: To make it possible to reduce greatly the number of signal lines between an input-output control part and input-output part by connecting the input-output control part and input-output part together via a cable and by transferring input information and outut information in series.
CONSTITUTION: Through input-output part 1, input information is input and output information is output; and arithmetic control part 3 performs fixed arithmetic on the basis of the input information and between control part 3 and input-output part 1, input-output control part 2 is provided which attains communication between the both. Then, control part 2 and input-output part 1 are connected together via cable 11, input information and output information are transferred in series, and in input-output part 1, each equipment performs series-parallel conversion. Consequently, the number of signal lines between control part 2 and input-output part 1 can greatly be reduced.
