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.
\nThe master of the ModBus network writes the preferred values in the table of the board.
\nThe table accepts a maximum of 512 words of 16 bits.
\nAll or part of the table may be the subject of a LoRa frame generation.
\nThe frame contains a maximum of 20 words of 16 bits.<\/p>\n

Ewattchcloud compatibility<\/strong><\/span><\/h5>\n

The data can be displayed directly on the Ewattchcloud platform. To do this, the modbus table must respect a format.
\nAn online tool is available here<\/a>. It makes it possible to obtain the modbus table model to follow according to the necessary data.<\/p>\n

Physical configurations<\/strong><\/span><\/h5>\n
    \n
  • Switches 2 and 3 must be in “OFF” mode (low position) so as to not setup the Pull Up and Pull Down<\/li>\n
  • Switch 1 must be in \u201cON\u201d mode (high position) if the board is the last slave of the bus. In the contrasting case, switch 1 must be in \u201cOFF\u201d mode (low position).<\/li>\n<\/ul>\n
