title: Python modbus library
body: <p>I have to control a modbus device with a serial interface. I've got not experience with modbus. But my short research revealed several modbus libraries</p>
  
  <ul>
  <li><a href="https://pypi.python.org/pypi/pymodbus" rel="noreferrer">pymodbus</a></li>
  <li><a href="https://pypi.python.org/pypi/MinimalModbus/" rel="noreferrer">MinimalModbus</a></li>
  <li><a href="http://code.google.com/p/modbus-tk/" rel="noreferrer">Modbus-tk</a></li>
  <li><a href="https://github.com/AdvancedClimateSystems/uModbus" rel="noreferrer">uModbus</a></li>
  </ul>
  
  <p>What are the advantages/disadvantages, are there even better alternatives?</p>
