Introduction to the tables of coils and registers used for accessing WaterMaster parameters using Modbus.
The document provides a detailed Modbus protocol reference for the WaterMaster electromagnetic flowmeter series. It defines the data representation formats, supported function codes, and the mapping of Modbus data‑types to internal device parameters.
Included are tables of alarm status inputs, read‑only and read‑write parameters, and action parameters, as well as specifications for word‑swap handling of floating‑point and integer values. The supplement also lists the function codes (e.g., 0x02, 0x03, 0x04, 0x06, 0x08, 0x10, 0x44) supported by the device.
