2.1 Major Features
1. Basic functions
[Up to 384 input/output points]
The number of input/output points (up to 256
points) wired directly to the PLC and remote
input/output points (up to 256 points) on the
network (CC-Link) can be increased to 384
points in total.
[Powered extension units/blocks that can be
connected]
FX
2N
Series input/output powered extension
units/blocks can be connected.
Up to 8 FX
0N
/FX
2N
/FX
3U
Series special function
units/blocks can be connected.
(Among FX
0N
Series, only FX
0N
-3A can be
connected.)
[Program memory]
The PLC has a 64K-step RAM memory.
Use of the memory cassette enables the
program memory to be used as flash memory.
[Operation instructions]
Various instructions, such as floating-point and
character string processing instructions and
scaling instructions, are provided.
[Built-in RUN/STOP switch]
The PLC can be started and stopped with the
built-in switch.
RUN and STOP commands can be given to the
PLC through a general-purpose input terminal or
peripheral device.
[Writing during RUN]
The programming software for personal
computer enables you to modify the program
while the PLC is running.
[Built-in clock function]
The PLC has a clock function to control the time.
[Programming tool]
Use a version of a programming tool supporting
the FX
3U
.

Refer to Chapter 5 "Version Information
and Peripheral Equipment Connectability"
in this manual.
*For peripheral devices not applicable to FX
3U
Series, specify FX
2N
Series or FX
2
Series for
model selection, and you can program the
sequence. In this case, use instructions and
devices within the ranges common to FX
3U
Series and the selected model of PLC.
[Remote debugging of program]
Use of programming software (GX Works2, GX
Developer) enables you to remotely transfer
programs and monitor PLC operation through a
modem connected to the RS-232C expansion
board and RS-232C communication special
adapter.
2. Input/output high-speed processing

2) Input terminals of high-speed input special
adapter (FX
3U
-4HSX-ADP)
- Input of differential line driver
- 1-phase 200 kHz x 8 points (when 2 units
are connected)
- 2-phase 100 kHz x 2 points (when 2 units
are connected)
