Key changes:
Component Improvements
Services
- Added the IEasyUAClientConnectionControl service on the EasyUAClient component. It provides methods to control the OPC UA client connections to the server, and contains methods like LockConnection and UnlockConnection. When the connection is locked, the component will attempt to open it and keep open, and will not automatically disconnect from the server after the connection is unused for certain time. The service is also available via COM, as _EasyUAClientConnectionControl.
Component Refactorings
OPC UA
- The ServerConditionChanged event, previously available on the IEasyUAClient interface, has been moved to a new service, IEasyUAClientConnectionMonitoring, available from the EasyUAClient component. The service is also available via COM, as _EasyUAClientConnectionMonitoring.
Examples
OPC UA Client-Server
- Added a C# example showing how to lock and unlock connections to an OPC UA server, using the new IEasyUAClientConnectionControl service.
