The tool provides a straightforward interface for interacting with PLCs and other ModBus-enabled equipment directly from the terminal.
Key Features:
  • Supports both ModBus RTU (serial) and TCP protocols
  • Command-line interface for easy scripting and automation
  • Read and write access to coils, discrete inputs, and registers
  • Supports various data types and word orders
Use Cases:
  • Debugging and testing industrial PLC connections
  • Automating device configuration via scripts
  • Monitoring sensor data from ModBus-enabled devices
Alternatives:
  • modbus-cli – Python-based alternative with similar CLI functionality
  • qmodbus – Qt-based GUI application for ModBus communication
