Modbus Slave (Server), allowing users to send requests and monitor responses in a human-readable format. 🛠️ Software Overview The Simply Modbus suite includes several distinct tools tailored for different communication types and roles: Simply Modbus RTU Master: Connects a PC to Modbus RTU (serial) slave devices. It displays raw hex data alongside interpreted register values. Simply Modbus TCP Client: Used for testing Modbus TCP/IP servers over Ethernet. It allows for quick connection testing and register reading/writing. Simply Modbus Slave: Emulates a Modbus device on your PC. This is useful for testing Master software or hardware without needing physical equipment. 📘 Key Technical Concepts To use Simply Modbus effectively, it is essential to understand the four primary types of Modbus registers it interacts with: zeroinstrument.com Register Type Access Description Coils Read/Write Single-bit (On/Off) values, typically for relays or switches. Discrete Inputs Read-Only Single-bit status indicators from external devices. Input Registers Read-Only 16-bit values often used for sensor data or measurements. Holding Registers Read/Write 16-bit values used for configuration or multi-state status. ⚡ Setup and Operation Using the software typically involves three main steps: 1. Physical Connection For
Engineers use Simply Modbus Master to verify that a new Modbus slave (e.g., flow meter, VFD, power monitor) responds correctly before integrating with a PLC or SCADA.
Its simple GUI is ideal for teaching Modbus protocol structure, addressing (0-based vs 1-based), function codes, and data encoding (endianness).
