11.5.4 How do I configure it?
Follow the instructions below to change the communication of a Sommer-device (in this example a
RG-30) to Modbus:
1. Connect the USB to RS-485 converter to the data cable of the Sommer-device and a USB port
on your PC.
2. Connect the sensor to a power supply with the specified rating.
3. Start the Commander software on your PC.
4. Establish a connection to the Sommer-device.
5.
Download the sensor’s parameters in the
Parameters (F2)
tab and save the parameter list on
your PC.
6.
In the parameter list navigate to Technics and open the menus
RS-485 protocol
and
RS485
and take a screenshot of the associated parameters. This and the previous step are helpful if
you need to switch back to the standard communication mode at a later time.
