Reads and writes Modbus holding registers and coils, and reads input registers, then standardizes the raw values so an AI agent can work with them. Connections can use TCP, UDP or serial, configured through environment variables. A prompt is included for analyzing register values.

Use cases

  1. 01Read a group of holding registers from a device
  2. 02Write a coil value during commissioning
  3. 03Ask an agent to explain what a register reading means
