4.2.1 About FL-net Protocol
FL-net is an open FA network that was standardized by the Japan FA Open
Systems Promotion Group (JOP) of the Manufacturing Science and Technology
Center (MSTC) under the Ministry of International Trade and Industry (MITI). It
has been established in the Japan Electrical Manufacturers standards (JEM
1479) and is becoming very popular.
FL-net enables personal computers and FA controllers, such as programmable
controllers (PLCs) or computerized numeric controllers (CNCs), by different
manufacturers to be interconnected, controlled, and monitored, as shown in the
following illustration.
The following illustration shows the positioning of the FL-net.
FL-net (Version 2.00) Unit specifications have been designed to conform to
Japan Electrical Manufacturers standards (JEM 1479: 2001). It cannot be
connected to communications devices based on the previous standards (JEM
1479: 2000).
The most recent FL-net specifications can be downloaded from the home page of
