Honeywell Sieger System 57 Modbus Interface Module Kit Operating Instructions

It is recommended that the host system be programmed to use Function 02 to collect alarm and status data from all channels. If the alarm function needs to be reset, Function 06 or 16 should also be implemented.

Modbus Function Reference

Supported Features

Function 02: Read input status, can read channel status bits, each sub channel has 11 status bits.

Function 03: Read the hold register. The host can read the contents of the hold register and can read up to 35 registers per frame.

Function 04: Read input registers, with two types of input registers: analog signal value and animation value. A maximum of 64 registers can be read per frame.

Function 06: Preset a single hold register.

Function 16: Preset multiple hold registers, up to 35 registers can be set per frame.
