Chapter 1: Outline

An FL-net module (JW-20FL5/20FLT, JW-50FL, FL-net board (Z-336J)) is an interface module use to connect a
programmable controller (JW20H/30H, JW50H/70H/100H), J-board to an FL-net. FL-net is an open network
that connects production equipment and controllers from multiple FA (factory automation) venders, to create a
unified production process. This network works as an intermediary between information networks and produc-
tion networks, and makes it possible to connect control devices (such as personal computers or programmable
controllers, hereafter referred to as PCs), to numeric control devices (CNCs), and robot controllers (RCs). The
Ethernet is used as a world standard communication method to allow communication between pieces of OA
(Office Automation) equipment.

FL-net employs an FA link protocol as an application layer.
Features of the FA link protocol
1 Uses the Ethernet UDP/IP communication protocol.
2 Using a Master-less, Token method, the system prevents data transmission conflicts and guarantees
the transfer of data within a specified time.
3 Employs a shared memory system (shares information between each of the nodes).
4 Nodes can automatically enter and leave the network.
Features of the JW-20FL5/20FLT, JW-50FL, Z-336J
1 FL-net compatible (uses the FA link protocol)
2 Supports cyclic transfers and message transfers.
3 Supports exchange of data between SHARP PCs using the SEND/RECEIVE function. (A unique
function of SHARP equipment)
4 Allows remote programming and remote monitor functions between SHARP PCs. (A unique function of
SHARP equipment)
