Modbus TCP communication with FRONIUS GEN24 Inverter (PV)

I am trying to read and control a FRONIUS GEN24 inverter via Modbus TCP. I have basic problems with the connection to the inverter.
Has anyone already done this and if possible an example? That would be really cool.

In case nobody replies with example, you will need to start from the manual of your device.

Then the next step would be to try to read out the values by some modbus simulation program that has some message logging capabilities since those were limited in OH.

When you get that working then try to connect the OH to your device.
