@Diederik new release of the beckhoff plugin is about the be released. I have done some major changes. It now supports route request, so it requests a route on the plc if given credentials, and the plc creates the route. Tested with tc2 and tc3. Fixed some small handler bugs, added more debug, with all ads error messages in readable text. Better reconnection support. This also works now better inside docker network with no port forwarding or host network. Support for latest subscription/read mode in the latest runtime.
