ModbusTCP

Hey Guys,

I know this is off topic but didn't knew who else to ask to. I have written my own Modbus-TCP Protocol and I'm able to read words. But i don't know how to read floating points and characters. Any help in that direction would be greatly appreciated.

The common Modbus protocol does not support floating or strings directly. You read the data as words, then convert them. For example, read 2 words, arrange the bytes, then convert to a single type. In .NET you can use BitConverter

Hi Archie,

Thanks for the support. I'm already using
Dim dat As Byte() = BitConverter.GetBytes(CShort(IPAddress.HostToNetworkOrder(CShort(word(x)))))
to get word data

what can we use for the floating point numbers.
