-------------------------------------
Hi [~cdutz],
Thank you for your reply. Rack and slot are provided via the connection string.
Since I want to adress rack 0 and slot 2 adding "/0/0" to the connection
string should not lead to the expected result as well. I still checked whether
this leads to any kind of working connection but I get the same kind of error.
I will look further into that issue and will test it with th S7-1200 tonight.
> S7 is terminating the connection during handshake
