INFORMATION TRANSFER SYSTEM USED IN FACTORY

摘要

An information transfer system, to be used in a factory, which allows information to be easily transmitted between controllers without requiring a complicated wiring of a communication line and a complicated communication protocol. A controller for each forming cell (Ai), a carriage controller (C) which controls an unmanned carrying means (D) and a warehouse cell (C), and a centralized controlling equipment (B) are connected to each other with an Ethernet line (100). Information is transmitted among these controllers via a common information storage (107). There is no necessity of installing communication lines parallelly between these controllers, and there is no increase in the number of I/O ports and communication lines. Therefore, a complicated wiring of the communication lines is prevented, resulting in the reduction in cost required for installation of the system.
