Transmitting information on IoT networks (Sigfox/LoRaWAN)
a. Keep-alive frame
This frame is sent to the network instead of the periodic frames if no Modbus frame is configured.
Frame format:
Byte 1 2 3 4 5 6
Data 0x01
Power supply voltage of radio
core on standby (millivolts –
typically 3300 mV)
Power supply voltage of radio
core when transmitting
(millivolts – typically 3300 mV)
0x64
b. Periodic frame (or triggered by pressing button)
This frame is sent to the network at a regular, configurable interval (the statement period).
Frame format:
Byte 1 2 3,4 ...
Data 0x03 Header Values of Modbus registers and/or bits read from the slave(s)
The header is a configurable parameter and must be set correctly to decode the frame. Modbus registers are sent in
a 2-byte format in MSB order.
c. Error frame
This frame is sent to the network when a Modbus or internal error occurs. Internal errors may arise due to an incorrect
Modbus configuration.
NOTE
This frame replaces a faulty radio frame. If the data in the radio frame were valid, they will be lost.
