title: Is there an http-API for Siemens Logo
body: <p>I have to renew an old house automation system and am thinking about the Siemens Logo control system. A requirement is that the states of the input and output ports can be read from a c# application.<br>
  Since some of the logo modules have Ethernet ports, I thought that they probably support reading and writing the port states via http. However, I have not found information about such a feature.</p>
  
  <p>Is there someone reading and writing the port-states of a Siemens Logo from within c#? Is there a documented API, hopefully a HTTP-API? Or can someone recommend me another automation system, which has such an API?</p>
