Illegal Adress Problem

[MGGEL]

Hi,
I get an "IllegalAddress" Message when I try to read a register.
But the register is correct and it exists is in the documentation:

Source:
response = client.read_input_registers(40003, 1, 0)

Logging:

Fehler beim Lesen des Registers: Exception Response(132, 4, IllegalAddress)

If i try to read any register above 9999 the message IllegalAddress occurs.
Might that a problem of the bit order or something like that?

pymodbus convert to big endian automatically as you can see in the debug log. Big endian is defined by the modbus protocol as the only way to transmit data.

The exception is a response from your device "illegal address" so you might want to read the device manual.
