How to reverse the order of each Input registers

[MonoLogueChi]

Sorry to bother you, I have encountered doubts when using modbus. I don't know how to get the correct value.

I need to read a float value, I use the following code

var axis0 = new ModbusTcpClient();
axis0.Connect(new IPEndPoint(IPAddress.Parse("192.168.0.233"), 502), ModbusEndianness.LittleEndian);
var a = await axis0.ReadInputRegistersAsync(1, 0, 2);

And I got the data

0x09 0x37 0x42 0x48

But I need the correct data to be

0x37, 0x09, 0x48, 0x42

I can only do a manual conversion now. Does FluentModbus have an API that can do automatic conversion?

Hi, you could use ModbusEndianess.BigEndian and read ushort data:

axis0.Connect(new IPEndPoint(IPAddress.Parse("192.168.0.233"), 502), ModbusEndianness.BigEndian);
var a = await axis0.ReadInputRegistersAsync<ushort>(1, 0, 2);

In that case you should get two ushort values with the correct byte order. Here is a bit more information: https://github.com/Apollo3zehn/FluentModbus/issues/86#issuecomment-2111742545

Thank you very much
