• 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

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.

FL-net DESCRIPTIONS

■ CYCLIC TRANSMISSION
• Transmitting discrete I/O status, analog I/O values and modules’ information on hardware commissioning, hardware errors, data errors and signal source node errors.
• Supplying word data transmitted from another devices to local output modules. The R3-NFL1 operation when this device exits the FL-net is selectable: Hold output, Clear output, Switch to the sub system’s control.
• Allotting the cyclic transmission output data of multiple devices bit by bit to local output modules.
■ MESSAGE TRANSMISSION
The module supports the FL-net defined functions listed in the following table. Only the server function is supported.
Server function allows the module to build a response frame to a request message.
Client function allows the module to transmit a request message and to receive its response frame.
