Remote Modbus Register Mapping
In addition to forwarding messages for other devices, the Repeater also reports status registers to the
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.
This data is accessible at the same Slave ID that the Repeater is configured for
