Tested with S7-300. After successful connection to PLC, if you disconnect it or turn it off the S7Client.Connected property stays always true.

Hi! Thank you for reporting this issue!

This connection property comes directly from System.Net.Sockets.Socket object and it is not notification based.

Look at this Stackoverflow thread for an explaination.

For such a case we realized Sharp7Reactive that also gives you such a notification in form of anIObservable<ConnectionStates> .
