Internal version number: 5.72

Key changes:

  • Support for Python.NET


Targeting

  • Python (with help of the Python.NET library) on Windows is now officially supported.
  • PyCharm is listed as one of the primary development environments.
  • Windows Server 2012 R2 (x64) is no longer supported.

Component Improvements

OPC Alarms&Events

  • Added AEEventData.ActiveTimeTicks property, and added alternate extension overloads of the IEasyAEClient.AcknowledgeCondition method. The new property and extension method overloads represent the event active time in UTC ticks rather than as DateTime. This is useful with Python.NET, which represents .NET DateTime as 'datetime' Python object, and thus reduces the required resolution (100 nanoseconds) to microseconds.

Examples

Platform: .NET

  • Added a set of more than 270 .NET examples in Python using the Python.NET package (https://github.com/pythonnet/pythonnet ). The previously provided smaller set of OPC Python examples using the Python for Windows (pywin32) extensions package (over COM API) remains in the product and continues to work, but we recommend using the Python.NET approach.

Documentation and Help

  • Methods and properties of all commonly used types are now consistently annotated with exceptions they may throw.
