title: Is there a good library for dealing with the Modbus protocol in .NET?
body: <p>Does anyone know of a good (preferably open source) library for dealing with the Modbus protocol? I have seen a few libraries, but I am looking for some people's personal experiences, not just the top ten Google hits. I figure there has to be at least one other person who deals with PLCs and automation hardware like I do out there.</p>
  
  <p>Open to any other materials that might have been a help to you as well...</p>
