INFORMATION TRANSFER SYSTEM USED IN FACTORY

摘要

An information transmitting system for use in a factory, which is capable of transmitting information among controllers simply without the complicated lead-around of a communication line nor the need of complicated communication protocol. A controller every molding cell Ai, a conveyance controller C to control an automatic conveyance means D and a stock cell C and a centralized controller B are connected to each other via an Ethernet line (100) to provide a common information storage means (107), and information is transmitted among the controllers through the common information storage means (107). Since there is no need of parallel communication lines between the controllers, an I/O port or a communication line may be prevented from increasing in number and the lead-around of the communication line is prevented from being complicated, resulting in a reduction of cost required for setting up the devices.
