title: C# Modbus get a lot register every 20 seconds
body: <p>I've made an application with C#, in this application I have to read every 20 second 840 registers of PLC via Modbus TCP. I use this library <a href="http://www.codeproject.com/Tips/16260/Modbus-TCP-class" rel="nofollow">http://www.codeproject.com/Tips/16260/Modbus-TCP-class</a>. When I use the method </p>
  
  <p><code>Master.ReadHoldingRegister(ushort id, byte unit, ushort startAddress, ushort numInputs)</code> </p>
  
  <p>It return a bytes array of lenght 144 and not 1680, do you have any idea?</p>
