Hey,  I sometimes make different systems with a Logo.
now i would like to try something new with MODBUS.

I just can't figure it out or I don't understand.

I have a Victron Cerbo GX and it can be read with modbus.

I would like to measure the voltage at the input of my inverter.

with this readout I finally want to switch an output of the logo.

in the pdf i have a register list with the line i want to read.

Can someone explain to me how to read that line?
