Functioning in slave mode
This mode of functioning will be used when you wish, for example, to send back on the network LoRa the data coming from an existing ModBus network. The master of the ModBus network writes the preferred values in the table of
Functioning in master mode
This mode will be used when you wish to read counters configured in slave mode. The board issues Modbus requests to read each counter (it is the master on the network, the counters are the slaves) and then radio transmits the
Implementation and wiring
Pinout of the terminal block: Configuration with the: The resistances of polarization Pull Up and Pull Down must only be installed in a single place of the Bus, usually at the level of the master. In this case, move switches 2 and 3 to

Payload descriptions
The Tyness sensor transmits its data in raw format. The section below shows you how to decode the frames (Payload) sent by the Tyness. Case of two inputs configured in counting: Case of two inputs configured in reading of status of inputs: Case of
Reading of the pulse indexes
It is possible to read with the Tyness Configurator software the number ofpulses counted by the Tyness.To do so, position the mouse on the image of the board, and the two countingindexes will display.
