Progress of FA has led to increase needs for integrated systems that interconnect various controllers and FA devices. Hence, standardization of networks has become an international trend.
The Japan Electrical Manufacturers’ Association (JEMA), in cooperation with the Manufacturing Science and Technology Center, the Japan Automobile Manufacturers Association, Inc., the Japan Machine Tool Builders’ Association , the Japan Robot Association, the Japan Electric Measuring Instruments Manufacturers’ Association and other relevant bodies, has engaged in the development, standardization, conformity testing and certification, and promotion activities for an open network FL-net comprising mainly programmable controllers (PLC).
Dissemination of the FL-net enables interconnection among different manufacturers’ equipment and devices, and configuration of flexible and open FA systems.
