The FX2N-20MT is a highly versatile and feature-rich programmable logic controller (PLC) designed for industrial automation applications. It is compatible with popular programming software and provides a wide range of functions to meet various automation requirements.
Basic Functions:
- Watchdog Function: Ensures system reliability by supporting a watchdog function, compatible with the original PLC.
- External Interrupt Function: Offers external interrupt functionality on all six channels, allowing pulse capture through X0-X5.
- Password Protection: Allows setting a password to secure the program. Setting the password as “12345678” makes the program unreadable, but it still permits the modification of soft component data.
- Component Compatibility: Except for D registers, this PLC is compatible with other components similar to the original.
- Data Retention: Supports data retention during power loss. All data is retained in FLASH memory and is verified during power-up.
- Program Verification: Verifies the ladder diagram program during download, ensuring program integrity.
- Program Check: Continuously checks the program instructions and component range during operation. Any issues are reported as faults.
- Run/Stop Indicators: The RUN indicator indicates the operating mode (flashes in RUN, off in STOP).
- Error Indicators: The ERR indicator indicates faults (blinks for minor faults, remains on for serious faults).
- Constant Scanning Mode: Supports constant scanning mode with configurable parameters.
Optional Functions:
- High-Speed Pulse Output: Supports PLSY and PLSR instructions, enabling pulse output on four channels (Y0, Y1, Y2, Y3). Y0 and Y1 support up to 200kHz, while Y2 and Y3 support up to 100kHz.
- RTC Real-Time Clock Function: Supports real-time clock functions, which can be password-protected to prevent modification.
- Encoder Input Function: Provides encoder input for up to two channels of AB phase input with a response of up to 60kHz. It also supports high-speed counters, SPD instruction, and 2x or 4x frequency configuration for increased precision.
- Dual Communication Ports: Offers two communication ports with support for programming port protocols. The second port also supports MODBUS-RTU protocols and can be switched using D8120, with baud rate configurations available.
Supported Instructions:
- Basic Instructions (All Supported)
- Step Instructions (STL and RET)
- 32-Bit Instruction Support, including additional P instructions
- Error Handling: A 6506 fault is detected when unsupported instructions are used.
The FX2N-20MT is a powerful PLC that combines a wide range of functions and versatile communication capabilities, making it an excellent choice for industrial automation applications that require precise control and data management.
