Parameters
- client
- The client object that will perform the operation.
- itemGroupArgumentsList
- List of OPC-DA item group arguments (each argument holds an OPC server and item descriptor, and OPC group parameters).
- minimumQuality
- The minimum quality of OPC-DA data to accept.
- millisecondsTimeout
- The number of milliseconds to wait, or System.Threading.Timeout.Infinite to wait indefinitely.
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, itemGroupArgumentsList.
