Invalid url for TCP transport

[floka94]

I try to connect to a S7 PLC on Slot 3. I tried several connection strings:

"s7://172.16.0.12/0/3"
"s7://172.16.0.12/0/3?controller-type=S7_400"
"s7://172.16.0.12/3/0?controller-type=S7_400"
"s7://172.16.0.12/3/0"

I always get an error:

Caused by: org.apache.plc4x.java.api.exceptions.PlcRuntimeException: Invalid url for TCP transport

Which version of PLC4X are you using? I think we've changed that rack and slot setting to use a default and to be overridable via query options ... please have a look here: https://plc4x.apache.org/users/protocols/s7.html

So I would assume you have to use something like:
"s7://172.16.0.12" "s7://172.16.0.12?remote-rack=1&remote-slot=2" "s7://172.16.0.12?remote-rack=1&remote-slot=2&controller-type=S7_400"
If you want to override the local rack and slot, there are counterparts for that.

I use version 0.10.0.

Ah thank you very much! It seems I used an outdated code example! Now everything is working as expected!
