[Extension()] [ElementsNotNull()] [NotNull()] public: static array<ValueResult^>^ WaitForMultipleItemValues( IEasyDAClient^ client, IReadOnlyList<DAItemArguments^>^ itemArgumentsList, DAGroupParameters^ groupParameters )
Parameters
- client
- The client object that will perform the operation.
- itemArgumentsList
- List of OPC-DA item arguments (each argument holds server and item descriptor).
- groupParameters
- Contains subscription parameters, such as the requested update rate.
Return Value
The function returns an array of OpcLabs.BaseLib.OperationModel.ValueResult objects. The indices of elements in the output array are the same as those in the input list, itemArgumentsList.
