A manufacturing line control system wherein the hardware region of a main memory is divided on basis of different pieces of information to be stored, the main memory being in a CPU board within a line computer which synthetically judges and processes data transmitted from a manufacturing line; and access control portions are disposed on each of the regions for performing high speed access upon instruction of identical page by a microprocessor. Various analog signal, digital signal and status signal issued from a product passing through the manufacturing line are inputted from the line computer into various equipment installed on the manufacturing line, and control signals are transmitted to the various equipment by a line controller including an input-output portion with which a plurality of card equipment is detachably provided for the application of various types of manufacturing line. The system achieves automation at the manufacturing line site, reduces power consumption, stabilizes manufacturing at high quality, enables efficient small scale manufacture of many different types of products and enhances operability.
