Abstract

PURPOSE: To omit the complicated switching process for the computer system containing plural units of operation boards and computer by installing the connection switch controller of the operation board between the computer and operation boards.
CONSTITUTION: Computer 1 does not use the connection state of operation boards 2 and 3 as the selection conditions of reception parts 4AA and 4AB, and transmits the information mechanically to parts 4AA and 4AB decided within the computer. The information sent out performs the decision of transmission parts 4CA and 4CB as well as the information compounding via register 4BA and switch part 4BB. Accordingly, the switching process is carried out locally for the operation boards, thus omitting the switching process at computer 1 which is caused by the connection and separation.
