The OPCUA32 driver now supports Type Definitions in accordance with the OPC UA specification version 1.04 and higher for the communication of user-specific types. For compatibility reasons, a previous version of the OPC UA specification 1.04 can be selected for older OPC UA server versions or for Custom Types for the communication.
For this purpose, the option Extension objects support has been added to the Advanced settings tab in the configuration dialog. The OPC UA specification for driver communication can be selected from a drop-down list .
Event Notifier driver object type variables now get the switching value and the Union field in the JSON string. In doing so, values of an AssociatedValue that are received for alarms of a SIMATIC system are mapped as a Union to the EventNotifier JSON string.
