Ich würde gerne bestimmt Modbus RTU Slave Adressen auslesen,
leider bekomme ich keine Werte vom Bus.
Verbindung erfolgt über einen Raspberry mit Modbus RS485 Adapter,
welcher erfolgreich verbunden ist.

Mit einem IOBroker kann ich die Daten erfolgreich auslesen.

In der Modbus_COM_Port => Modbus_Serial_Device habe ich
Input Register 4000 %QW und Startadressen auf Input Register 3000,
als Variable ein Array[0..2999] of Word, kann aber keine Werte auslesen.
