Hi,

I am trying to configure a Modbus sensor for a solar charger over IP.

I can read the value using tester software from my PRTG server, but am unsuccessful on PRTG. https://www.se.com/us/en/faqs/FA180037/

The registers are detailed in the document e.g. Input register Address 0x3100 / 12544

The error is "The sensor could not retrieve data from the server. (Request reading 1 input registers starting at 12288 failed: No error)" I am using the current release PRTG Network Monitor 21.3.70.1629 x64

Thanks for any assistance.

Hello there,

For those cases it is usually best to open an official support ticket, since we can handle the request in an easier way there.


Kind regards,
