Ping PLC LOGO8 working correct, can also connect via telnet 10.0.0.220:102

pingplc

telnet

I recieved the same error on linux opensuse 42.1 with python snap7

Can anyone help regarding this error - there must be something I missed because why will one connect and the other one doesn't

hi @Scorpshn. I really have no idea, but it is very unlikely that is has to do something with python-snap7. I don't think you well get a lot of response here in our bug tracker. I'm sorry but i'm closing this issue.
