FX3U Mitsubishi PLC main features
[Maximum 384 points of input and output points]
[Extension unit/module that can be connected]
The input and output expansion devices can be connected to the FX2N series of I/O expansion units/modules. In addition, up to 8 FX0N/FX2N/FX3U series special function units/modules can be connected. (FX0N series can only be connected to FX0N-3A)
[program memory]
Built-in 64K steps of RAM memory. In addition, the program memory can be changed to flash memory by using a memory cartridge.
[computation instruction]
In addition to floating-point numbers and string processing instructions, it also has a wealth of instructions such as fixed-coordinate instructions.
[Built-in RUN/STOP switch]
The RUN/STOP operation can be performed by the built-in switch. In addition, RUN/STOP commands can be issued from a common input terminal or peripheral device.
[Support RUN write]
With the programming software for the computer, the program can be changed while the programmable controller is RUN.
[Built-in clock function]
Built-in clock function, you can perform time control.
【Programming Tools】
Please use the programming tool corresponding to the FX3U version. → Refer to the chapter 5 chapter version information and the connection status of peripheral devices.
* In peripheral devices that do not correspond to the FX3U series, you can select FX2N series or FX2 series for programming. At this time, the usable range of commands and devices is within the range of both the FX3U series and the programmable controller of the selected model.
[Support remote debugging]
If you use the programming software (GX Developer), you can perform long-distance program transfer and operation monitoring of the programmable controller by connecting the RS-232C function expansion board and the modem on the RS-232C communication special adapter.
[High speed counting function]
1) Input terminal of the base unit.
- Input of open collector type transistor output
- Single phase 100kHz × 6 points + 10kHz × 2 points
- Two-phase 50kHz × 2 points
2) Input terminal of high-speed input special adapter (FX3U-4HSX-ADP)
- Differential input
- Single phase 200kHz × 8 points (when 2 units are connected)
- Two-phase 100kHz × 2 points (when 2 units are connected)
[Input interrupt function (with delay function)]
The interrupt subroutine can be prioritized by the ON width or an external signal with an OFF width of at least 5μs (X000 to X005). (There are also timer interrupt and high-speed counter interrupt function)
[Pulse output function]
1) When using the output terminal of the base unit (transistor output type), the 3-axis can simultaneously output pulses up to 100 kHz (open collector output). (Y000, Y001, Y002)
2) If two high-speed output special adapters FX3U-2HSYADP are used, the 4-axis can simultaneously output pulses up to 200 kHz (differential linear drive output).
