FL-net Overview
FL-net is an open FA network that was standardized by the Japan FA Open
Systems Promotion Group (JOP) of the Manufacturing Science and Technol-
ogy Center (MSTC) under the Ministry of International Trade and Industry
(MITI). It has been established in the Japan Electrical Manufacturers stan-
dards (JEM 1479) and is becoming very popular.
FL-net enables personal computers and FA controllers, such as programma-
ble controllers (PLCs) or computerized numeric controllers (CNCs), by differ-
ent manufacturers to be interconnected, controlled, and monitored, as shown
in the following diagram.
FL-net Positioning
FL-net Unit specifications have been designed to conform to Japan Electrical
Manufacturers standards (JEM 1479: 2001). It cannot be connected to com-
munications devices based on the previous standards (JEM 1479: 2000).
The most recent FL-net specifications can be downloaded from the home
page of the Japan Electrical Manufacturers Association (http://www.jema-
net.or.jp/English/).
The following table shows the relationship between these standards and the
FL-net Units manufactured and sold by OMRON.
