Please post a sample code, I used it and it was returning the correct value.
from sharp7-example.
Hello,
Let's use:
private void WriteToPLCexampleTemporary()
{
S7.SetIntAt(BufferWrite, 2, -10);
int Result = m_s7Client.DBWrite(1, 0, 10, BufferWrite);
S7MultiVar Reader = new S7MultiVar(m_s7Client);
Reader.Add(S7Consts.S7AreaDB, S7Consts.S7WLByte, 1, 0, 10, ref Buffer);
Result = Reader.Read();
int a = S7.GetIntAt(Buffer, 2);
}
It returns 65526 instead of -10
I propose this solution
public static int GetIntAt(byte[] Buffer, int Pos)
{
return (int)((Int16)((Buffer[Pos] << 8) | Buffer[Pos + 1]));
}
from sharp7-example.
I verified the code and I had the same issue. I will contact the author to update the library,
from sharp7-example.
Fixed in Sharp7 1.0.3.
Updated the example with the latest sources.
Thanks for the contribution.
