title: Connection and upgrade of project with TIA portal v13 sp1
body: <p>I have a project built with STEP 7 Basic V13.  I try to use it with STEP 7 Basic V13 SP1 upgrade. But after the load with TIA, when I want to do the connection, I get the error "device not reachable". Sometimes, this error becomes "incompatible device". I am not sure what is happening with the configuration.<a href="https://i.stack.imgur.com/jjrmR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jjrmR.png" alt="enter image description here"></a></p>
