FUNCTIONS & FEATURES

■ R3-GFL1 enables the other interface module to access field signals as virtual I/O data via FL-net. No ladder programming is required to assign these I/O signals.
■ 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 as virtual analog signal.
The FL-net Configuration Builder software (model: R3-NFLBLD) is used to assign these virtual analog signals on the common memory in the bit or word units.
■ Request/Response type message communication, accessing I/O data only when necessary, is also possible.

CAUTION !
• FL-net standard requires a dedicated Ethernet bus for the FL-net compatible devices. Connecting the R3-GFL1 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.

CAUTION

• When selecting network modules, note that this unit is not designed to be used with network modules of certain types or versions.
• This unit CANNOT be used with R3-NC2, R3-NEIP1, R3-NFx, and R3-NLx.
• This unit CAN be used with:
   R3-NM3 and R3-NML3 of firmware version V1.00 or higher;
   R3-NC1, R3-NC3, R3-NDx, R3-NE1, R3-NFL1, R3-NM1, 
   R3-NM4, and R3-NP1 of firmware version V2.00 or higher;
   and 
   other models of any firmware versions.

FL-net DESCRIPTIONS

■ CYCLIC TRANSMISSION
• Transmitting virtual I/O value, this module's information and node error of signal source.
• Supplying common memory word data transmitted from another devices as virtual output.
• If the node that this module is accessing has been removed from the common memory, the operations “Hold output” and “Clear Output” are selectable.
■ 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.

PC REQUIREMENTS (provided by the user)

The following PC environment is required to run the R3-NFLBLD program.

EXTERNAL VIEW

TRANSMISSION DATA DESCRIPTIONS

Use the DIP SW located at the side of the module to specify module allocation.
1 module is equivalent to 1 I/O module with 16 words analog input and 16 words analog output. Max. 8 modules (128 words input, 128 words output) transmission is available. R3-GFL1 seems as if max. 8 I/O modules are mounted to 8 slots via FL-net.
The input of the module is processed as follows.
  [FL-net Communication] --> [R3-GFL1 Module] --> [R3 Base] --> [R3 Communication Module]
The data set with output tab of R3-NFLBLD to input is transmitted to R3 communication module. Output is reversed. The data set with transmitting area 1 and transmitting area 2 is transmitted to FL-net.
Note: Do not mount any modules in the slots which are occupied by virtual modules. If a real I/O module is mounted in the slot, an internal bus error occurs. Max. 16 real I/O modules and virtual modules are available. The interface module can not read the data for more than 16 modules.
■ WHEN R3-GFL1 IS MOUNTED ON SLOT NO. 2 (4 modules)
Real I/O modules are mounted on Slots No. 1 and 2, however, the network module (R3-NE1) recognizes that each of Slots No. 1 to 5 is occupied.  That is, R3-NE1 recognizes R3-SV4 mounted on Slot No.1 as it is and recognizes R3-GFL1 mounted on Slot No.2 as divided into four modules and occupying Slots No. 2 to 5.
