Features/Functions

Autonomous operation reduces development man-hours for higher-level systems (auto mode).

自律動作で上位システム開発削減(オートモード)

The unit automatically takes a reading and transmits the data when the power is turned on.
Various settings can be made via a browser.
There is no need to run a complex program from a PC or other device.

Data can be sent not only to a server on the LAN, but also to a cloud server on the Internet via a router.

The server side can receive data via a web server, etc. Secure communication is possible using HTTPS.
System developers can easily start a system using RFID reader/writers.


Two models: specified low power models that do not require radio station applications, and premises radio stations (licensed stations).

Depending on the application, you can choose between a specified low power type (FRU-4025Plus), which does not require the use of a radio station, and a high power, 4-port antenna, premises radio station (licensed station) type (FRU-4100Plus).

Supports a wide range of communication methods

多様な通信方式をサポート

LAN and serial interfaces plus DIO.
Capable of receiving digital inputs from sensors and digital outputs to peripheral devices.
Number of antenna ports: 2 (FRU-4025Plus), 4 (FRU-4100Plus).

Supports LAN connections (socket and HTTP/HTTPS communication)

HTTP/HTTPS communication supports the GET and POST query methods and the JSON method.

Small, space-saving

Compact size, LAN connectivity and a separate antenna reader/writer allow greater freedom of installation location. A variety of connector configurations can be selected to suit the application.

PLC link function

PLCリンク機能

The PLC Link function writes the IC tag data to memory in the PLC simply by setting it up.
There is no need to set up a ladder to send complex commands.
A trigger from the PLC or a sensor etc. is used to trigger the reading detection of the IC tag, which then writes the IC tag data to the specified address in the PLC.

*Can be used with Mitsubishi Electric and other PLCs from various manufacturers via LAN connection. Please refer to the manual for details of compatible models.
