s7netplus
A .NET Library for Siemens S7 Connectivity
Overview
S7.Net Plus is a continuation of the work done on the S7.Net project by Juergen1969. I found the library simple and effective, but the project has languished unchanged since late 2009.
I was doing some automation work already and saw a few places where the code base could be improved. Because Juergen did not respond to my request for committing code, I decided to pick up where he left off here on GitHub.

Running the tests
