Mitsubishi FX3U series PLC processing speed industry leader, reached 0.065us/basic instructions, built-in 64K large capacity memory, greatly increased the number of internal soft components.
The transistor mainframe has built-in positioning function of up to 100kHz with three axes, and adds new positioning instructions: DSZR with DOG search, DVIT with interruption and TBL, which makes positioning control more powerful and more convenient to use. Up to 10 ADP special adapters can be connected to the left side of the PLC host. Including high-speed input and output adapters, analog input and output adapters and temperature input adapters, these adapters do not occupy system points. FX3U strengthens the instruction function and provides up to 209 application instructions, including communication with Mitsubishi frequency converter, CRC calculation, generating random numbers and so on. Enhanced communication function, its built-in programming interface can achieve 115.2 Kbps high-speed communication, and can expand two communication interfaces, such as RS-232, 422, 485, USB, Ethernet, MODBUS, etc.
FX3G series PLC is the third generation micro-programmable controller launched by Mitsubishi Motor, which is upgraded and developed on the basis of FX1N.
FX3G series PLC has 3-axis positioning function, multiple positioning instructions, and easy to set up. It is the preferred model to build servo/step positioning system.
FX3G series PLC host has two high-speed communication interfaces (RS422 USB) and built-in 32K memory. Two levels of password can be set, each level of 16 characters, which enhances the password protection function. In standard mode, the processing speed of basic instructions can reach 0.21 ugs, which can realize floating point arithmetic. The left side of basic unit can connect up to four FX3U special adapters.

1. Operating speed, FX3U is the fastest.
2. Communication ports: FX3U can use three at the same time.
3. High-speed pulse output: FX3U series PLC can control three axes, one more axle than FX2N.
4. FX3U has more extension points than FX2N, and FX2N program can be directly imported into the same type of PLC of FX3U. It has no effect on the machine!
5. The biggest difference between FX3U and FX2N is that 3U has S/S terminal, through S/S terminal, PLC can be changed into leaky input or source input, FX2N does not have this function.

Expanded information:
FX2N is the choice of various applications from 16 to 256 input/output channels; FX2N series is miniaturized, high-speed, high-performance and all aspects are equivalent to the FX series of the highest-grade ultra-small program device. In addition to the independent use of 16-25 points input, it can also be applied to the connection between several basic components, analog control, positioning control and other special purposes. It is a set of PLC that can meet the wide variety of needs.
Connecting the expansion unit or expansion module on the basic unit, the flexible input-output combination of 16-256 points can be achieved. The host with 16/32/48/64/80/128 points can be selected, and the extension module with a minimum of 8 points can be used for expansion. It can be selected freely according to the power supply and output form.
Program capacity: Built-in 800-step RAM (input annotations) can use storage boxes, the maximum can be extended to 16K steps. There are many simple instructions, high-speed processing instructions, variable input filter constants, interruption of input processing, direct output and so on. Convenient instruction digital switch data reading, 16-bit data reading, matrix input reading, 7-segment display output, etc.
Data processing, data retrieval, data arrangement, trigonometric function operation, square root, floating-point decimal operation, etc. Special Purpose, Pulse Output, Pulse Width Modulation, PID Control Instruction, etc. External devices communicate with each other, serial data transmission, ASCII code printing, HEX ASCII transformation, check code, etc. The timer controls data comparison, addition, subtraction, reading and writing of built-in clocks.
