Hi, I'm really new here and just started with Nod-red.  
Is there someone who can give a complete designed flow to read registers from a Piko 5.5 inverter with a modbus tcp module.

Kostal give this example

\*Request telegram to sent: \*  
_05 62 DE A0 03 03 45 D8 00_

and then read back

\*Response from the inverter: \*  
_05 E2 DE A0 03 03 B8 0B 01 02 DA 00_

please can help someone?

Hello Becker, great your anwser.  
This is goes work with TCP connection.  
I want to do a power control of the PV and I thought that this only go with Modbus RTU do you know?  
Do you have the complete API information of dxsEntries for Kostal Piko-converters or where I can find it?
