* Add StringEx.ToByteArray(...) * Add Serialization.SerializeDataItem(DataItem) Supports StringEx VarType or offloads to SerializeValue method. * Use SerializeDataItem in S7WriteMultiple * Assume string length without header in StringEx.ToByteArray VarTypeToByteLength already assumed that StringEx declared count for the number of characters without the header, this now matches that behavior. * Add unit tests for StringEx conversions * Fix incorrect value passed to Encoding.GetBytes The length must actually be within string limits.
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
Unit tests use Snap7 server, so port 102 must be not in use. If you have Siemens Step7 installed, the service s7oiehsx64 is stopped when running unit tests. You have to restart the service manually if you need it.
