Lishui Controller Programming 【99% OFFICIAL】

Programming a Lishui (LS) controller typically involves three levels: adjusting basic parameters via an LCD display, using the official Lishui software for firmware updates, or installing open-source firmware for advanced control. 1. Basic Parameter Setup (via Display)

1. Create new project in IDE — select controller model and CPU slot.
2. Configure I/O mapping and communication ports.
3. Define global variables/tags (names, data types: BOOL, INT, REAL, STRING).
4. Build logic using chosen language (LD/FBD/ST).
5. Add PID controllers or math blocks as needed.
6. Implement alarms, interlocks, and safety conditions.
7. Simulate (if IDE supports) or compile to check errors.
8. Download program to controller and run in test mode.
9. Monitor variables online, adjust tuning and setpoints.
10. Save project and document version/revisions.

• Serial Communication: Lishui controllers communicate through a serial interface (e.g., UART, TTL). The programming cable connects the controller to the computer, allowing data transmission.
• Command Structure: Lishui controllers use a specific command structure, consisting of:

  Most Lishui controllers accept direct parameter changes via UART while locked. Instead, you must: Create new project in IDE — select controller

  • A main microcontroller (usually STM32 or Nuvoton ARM Cortex-M series)
  • MOSFET banks (e.g., 6x 3077 for 48V systems)
  • A DC-DC converter (for lights and auxiliary systems)
  • UART, CAN bus, or serial communication ports
  • Modbus RTU/TCP: map registers for inputs, outputs, coils, and holding registers. Set proper addressing offset (0 vs 1) per device.
  • Use locking or transaction checks when multiple masters access the same registers.
  • Implement heartbeat register to indicate controller is alive.
  • For SCADA/HMI: expose necessary tags only; use descriptive names and scaling (raw ADC → engineering units).
