Declaration and configuration of TX MODBUS

Go to the receiver configuration server . On the receiver configuration server, the Config TX tab allows the declaration and configuration of the TX MODBUS which will be paired with the receiver. To configure your TX MODBUS, click on the button +Add Sensor. A new window appears.

Below is the list of fields to configure:

If you wish to declare other slaves on this same TX MODBUS , you can click OK and continue editing by indicating a new slave number.

Once your configuration is complete, you can click Save Changes, then Cancel to finish and exit.

The RX MODBUS receiver supports up to 50 transmitters. Each slave configured on a MODBUS TX is equivalent to a transmitter in the receiver's Modbus table.

It is possible to configure several slaves with the same Modbus ID in order to read or write in more than 6 registers on this slave. For more details, please see this article.
