Remote I/O R3 Series

FL-net INTERFACE MODULE

(OPCN-2, Ver.2.0 supported)

Functions & Features

• FL-net (OPCN-2), Ethernet based, controller level network,

compatible remote I/O

• 10 Mbps/100 Mbps cyclic transmission for the maximum

of 4k bits + 256 words (1 word = 16 bits) allows data

shared among the devices connected to the bus

• FL-net bus extended to max. 500 meters, up to 2.5

kilometers with a repeater

• I/O data can be assigned to any bits or words in the

common memory

• No need of ladder programming

• Request/response type data access of message

transmission is also possible

• Any other network module can be assigned to the dual

redundant internal bus

• Supports multiple protocol of FL-net plus DeviceNet, CC-

Link, and others

• Masterless configuration allows the FL-net I/Os function as

local multiplex transmission system

FUNCTIONS & FEATURES

■ The R3-NFL1 is used to access field signals at the R3 I/O

modules via FL-net.

No ladder programming is required to assign these I/O

signals.

■ Analog and discrete input signals are transmitted

cyclically.

Any PC or PLC compatible with FL-net, up to 254 nodes, can

retrieve the updated data by accessing the common

memory without interfering with the communication traffic.

■ Analog and discrete input signals cyclically transmitted

from other devices can be output at the R3 output modules.

The FL-net Configuration Builder software (model: R3-

NFLBLD) is used to assign these I/O signals on the common

memory in the bit or word units.

■ The R3-NFL1, constantly scanning its I/O modules via the

internal bus, has the updated data always ready for a

request from the FL-net. High speed response without any

loss time is possible.

■ Request/Response type message communication,

accessing I/O data only when necessary, is also possible.

■ Dual redundant network configuration using two network

modules is available.

Two different network protocols, e.g. FL-net and DeviceNet

or FL-net and CC-Link, can be used to access one field

signal.

■ Masterless configuration allows two FL-net nodes function

as local multiplex transmission system.

CAUTION !

• FL-net standard requires a dedicated Ethernet bus for the

FL-net compatible devices. Connecting the R3-NFL1 to a

general-purpose LAN, or connecting a general-purpose

TCP/IP device to FL-net is Not allowed.

• FL-net uses UDP/IP protocol for transmission. ISDN, ADSL

or similar types of LAN are Not to be used.
