Parameters

client

The client object that will perform the operation.

This is typically the OpcLabs.EasyOpc.UA.EasyUAClient object.

The value of this parameter cannot be null (Nothing in Visual Basic).

argumentsAndMaximumSeverityList

List of tuples, where each tuple consists of OPC-UA monitored item arguments, and a maximum status severity determining when the wait is complete.

The value of this parameter cannot be null (Nothing in Visual Basic).

Return Value

The WaitForMultipleValues subscribes to the specified OPC-UA nodes&attributes, and monitor their data until they have at most the status severity specified for each item, an error occurs, or the alloted time elapses.

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.
