JA description of the FP3/FP10S MEWNET-TR system
The FP3/FP10S MEWNET-TR system is a network system that links FP3/FP10S CPUs and I/O field devices with
minimum wiring. The remote I/O control function allowsthe user to control the I/Oinformationofthe I/O units that are
connected. The I/O link function enables the exchange of I/O information when two FP3/FP10S CPUs are connected.

TERMINAL UNIT
xMaster station
The master stationconsists of the FP3/FP10S CPUand
FP3 transmitter master unit. The FP3/FP10S CPU
exchanges I/O information with the connected slave
stations through the FP3 transmitter master unit.
xSlave station
The FP I/O transmitter unit or expansion FP I/O
terminal unit is used as a slave station to increase the
number of I/O points. For details on slave station
units, see “1-3. Product Types ” on page 6.

JEquipped with a safety function for selecting the operation status when an abnormality occurs
When an abnormality occurs such as cable or power disconnection, and there is a communication failure even with one
single slave station, the control operation can be stopped for all the slave stations. It can also hold the output of a slave
station that is out of communication due to cable disconnection.
JEasy wiring and flexible alteration of the equipment layout
Because a twisted pair cable is used for input and output connections, wiring is easy and wiring errors can be minimized.
It also allows a flexible alteration of the equipment layout.

xThe FP3 transmitter master unit can be installed in an I/O unit mounting slot of the master backplane or expansion
backplane.
xAn FP3 CPU or FP10S CPU can be mounted with more than one FP3 transmitter master unit.
xThe number of controllable I/O points can be selected by operation mode selector Nos. 5 to 8 of the FP3 transmitter
master unit.
- You can select the number of input points to be 0, 32, 64 or 128.
- You can select the number of output points to be 0, 32, 64 or 128.
xWhen two or more FP3 transmitter master units are mounted, the maximum number of controllable I/O points is as
follows:
- FP3 MEWNET-TR system: 2,048 input points, 2,048 output points
- FP10S MEWNET-TR system: 3,072 input points, 3,072 output points
Note:
xThe number of I/O points is set to 0 at the factory. With this setting, the remote I/O control function cannot
be used.

JLimitations on unit installation
xMore than one FP3 transmitter master unit can be mounted; however, the following cautions should be observed.
- I/O occupation:
The total number of controllable I/O points should not be set higher than the number of I/O points of the FP3/FP10S
CPU.
< For FP3 CPU >
The maximum number of controllable I/O points is 2,048 for input and 2,048 for output.
For example, an FP3 transmitter master unit for which 128 input points and 128 output points are selected can be
mounted with up to 16 units.
< For FP10S CPU >
The maximum number of controllable I/O points is 3,072 for input and 3,072 for output.
For example, an FP3 transmitter master unit for which 128 input points and 128 output points are selected can be
mounted with up to 24 units.
- Current consumption:
Thetotalcurrentconsumptionofthe unitsused shouldnot exceedthe ratedoutputcurrentoftheirpowersupplyunit.
xThere is no restriction concerning the combination or mounting slot of the FP3/FP10S I/O units and intelligent units.
However, please note that I/O allocation is determined by the mounting positions and combinations of the units (I/O
occupation).
The I/O occupation points of an FP3 transmitter master unit are the same as the I/O points selected by operation mode
selector Nos. 5 to 8.
For example, when 128 input points and 128 output points are selected by the operation mode selector, the I/O
occupation is 128X and 128Y.
Notes:
xSee the “FP3/FP10S HARDWARE Technical Manual” for details about limitations on unit installation.
xThe maximum number of controllable I/O points for FP3/FP10S CPUs is set at the factory to 1,024.
IfthenumberofI/Opointsusedby theMEWNET-TRsystemexceeds1,024,changethebase wordnumber
using the NPST-GR software to increase the number of controllable I/O points.
See the “NPST-GR SOFTWARE Manual” and “REMOTE I/O SYSTEM Technical Manual” for details about
the I/O number allocation by base word number setting.
Example:To use 1,280 I/O points with a MEWNET-TR system, change the base word number from No. 64
(factory setting) to No. 80 using the NPST-GR software.

JCombinations of units set for the slave station (factory setting)
The FP3/FP10S MEWNET-TR can be connected with more than one FP I/O transmitter unit within the range of control
I/O point numbers set by the operation mode selector of the master station (FP3 transmitter master unit).
However, the maximum number of slave stations is 16 units for input and 16 units for output.
< Example of combination >
When setting the control I/O point numbers to 128 for input and 128 for output using the operation mode selector.
xSystemconfigurationwithonlythe 16-pointtype

- 16-input type ×8 units (128 inputs)
- 16-output type ×8 units (128 outputs)
xSystem configuration with only the 8-point type
FP I/O transmitter units
- 8-input type ×16 units (128 inputs)
- 8-output type ×16 units (128 outputs)
xWhen the system is configured with only4-point units, the maximum of 16 input unitsand 16 output units can be used
even if the setting is made for 128 input points and 128 output points. Therefore, only 64 points can be used for each,
as shown below.
- 4-input ×16 units (64 inputs)

The slave station can be connected with one expansion FP I/O terminal unit to increase the number of I/O points.
Note:
xThe 4-point type slave station (FP I/O transmitter unit) cannot be connected with the expansion FP I/O
terminal unit.

3. Controllable I/O Points and I/O Allocation
xThe I/O allocation example shown in the table below is for an FP3 transmitter master unit installed in slot No. 0 of the
master backplane.
xThe open circles (f) indicate the number of points used for input, and the closed circles (F) indicate the number of
points used for output.
< Example > When 32 input points and 32 output points are selected, the input point numbers are X0 to X1F, and the
output point numbers are Y20 to Y3F.

Notes:
xThe I/O points used in a MEWNET-TR system are selected by the operation mode selector of the FP3
transmitter master unit.
xThe first I/O numbers vary depending on the mounting position of the FP3 transmitter master unit and the
I/O occupation points of other units installed.

1Station monitor LEDs: LEDs that monitor the slave stations (station number 0 to F) connected to
the FP3 transmitter master unit.
-When ON: Connected to a slave station
-When flashing: A communication error at this slave station number
-When OFF: Not connected to a slave station
2Operation monitor LEDs: Indicate the operation and communication status of the MEWNET-TR
system. See following page.
3Selector for station monitor LEDs: Selects the unit type (input or output) of station monitor LEDs.
Input position (INPUT): Status of slave station (FP I/O transmitter
unit) input type is indicated by station
monitor LEDs.
Output position (OUTPUT): Status of slave station (FP I/O transmitter
unit) output type is indicated by station
monitor LEDs.
The selector’s upper state is “INPUT ( )” and the lower state is
“OUTPUT ( ).”
4Operation mode selector: Selects the MEWNET-TR communication conditions and sets the I/O
addresses. See following page.
5RS485 interface: Interface for MEWNET-TR communications.
6Mounting screw: A screw for attaching the unit to a master or expansion backplane.
7Connector: Connects to the slot on the master or expansion backplane.
