FL-net (FA LINK Protocol Network) module that has been rapidly spread as a next generation control system network.
It connects not only different types of equipment such as NC machines and industry robots, but also PLCs made by different manufactures through one network smoothly.

It adopts the master-less token method, assuring the real time capability. Al it can be easily assembled in your network by automatic subscribing and unsubscribing of nodes.
Cyclic transmission and message transmission are possible. An interlock, production instructions transmission, and production track record acquisition between equipment are possible via a same line.
By using our own SEND/RECEIVE instructions, data exchange between our PLCs is possible. Maintenance with the remote program monitor function is also easy.
Wiring parts such as wiring cables and hubs are common to those of Ethernet.
