Hi Chris. With the 0.6.1 (Aka Frankenstein code :-)) I solved every problem that I was finding to get to the handling of the subscription (Type handling, optimization, asynchronous responses from the PLC, etc.).
J ... is helping me to incorporate the code to the development branch. I am not a Git expert, and the last thing I want is to damage something jeje. Also, all these points are documented in Jira (including the pcap files). For my part, I am waiting next week to be able to install a VPN and give access to the S7-300 / 400 equipment (physical) and the tests can be finished.
