This document represents a summary of the changes between libplctag-v1.0.13 and libplctag-v1.1.0

Miscellaneous

• Updated libplctag.NativeImport reference from v1.0.17 to v1.0.34 The primary changes this includes for libplctag dependents are:
  • Added libplctag core binary for the osx64 target
  • Use AppContext.BaseDirectory instead of Assembly.GetExecutingAssembly().Location
• Added definitions for Simple DataTypes @jkoplo This provides definitions where only one pairing of PlcMapper with a datatype is likely (e.g. DINT <-> int) See https://github.com/libplctag/libplctag.NET/blob/master/src/libplctag/DataTypes/Simple/Definitions.cs
• Added debug logging events on the libplctag static class @timyhac See this for an example of using the event API, and this for an example of how to add libplctag debug events to the Microsoft Dependency Injection logger sink.
• Fixed bug where PlcType was no longer being passed to IPlcMapper for Tag<T> @jfontsaballs

Tag<T>

• New value return for Read/ReadAsync and additional overloads for Write/WriteAsync to pass in the value to be written. @jkoplo

  // Allows you to write this
  var result = myTag.Read();
  myTag.Write(1234);
  
  // instead of this
  myTag.Read();
  var result = myTag.Value;
  myTag.Value = 1234;
  myTag.Write();
