SignalFire Telemetry Rev 1.7
Remote Modbus Register Mapping
The Sentinel Node sends data to a SignalFire Telemetry Modbus Gateway. The data that is
sent to the gateway is available at the gateway in registers where it can then be read by a Modbus RTU.
In addition to the pre-configured registers read from the attached sensor, the Sentinel will send system
information in 16-bit registers listed in the table below. This data is accessible at the same Slave ID as the
connected Modbus device.
