Hi Denis, if you are using PLC4X 0.7.0 or newer, the connection syntax has changed slightly. You no longer provide Rack and Slot the way you did in 0.6.0 and below. Please have a look at our documentation for all options: https://plc4x.apache.org/users/protocols/s7.html
So, in your case it would be: s7://192.168.1.222?remote-rack=0&remote-slot=2&controller-type=S7_300<http://192.168.1.222/0/2?controller-type=S7_300> Hope that helps, Chris Von: Denis Leite <[email protected]> Gesendet: Donnerstag, 8.

We have included rack and slot information to communicate with S7-300 but it didn´t work. The error message is in the attached image. We tried these: s7://192.168.1.222/0/2?controller-type=S7_300<http://192.168.1.222/0/2?controller-type=S7_300> s7://192.168.1.222/0/2<http://192.168.1.222/0/2> This is where we got references: https://riot.community/examples/http-plc4x.html https://youtu.be/MIp_0OcDTr4?t=2770 Can someone help us to find out where the problem might be? Regards, Denis [cid:ii_kn94u9dq0]
