Format of Float Value

[fatih_oez]

Hi All,

I have a problem, when i read foat value.

I read float value from some sensors via ModBUS TCP. when I read the values on ModBus Poll Test software, I can read value true and its format is ABCD but I can read this value on WinCC OA as format CDAB. How can I shift tihs format?

Thanks in advance...
Have a nice day,

Maybe the problem can be solved with the config-entry "littleEndianRegister" for the Modbus-driver.
[mod]
littleEndianRegister = 0/1

1 is the default value.
After defining the config entry you have to restart the Modbus driver.
