The VIs on this palette can return storage error codes. Get Object Info VIReturns information about the object you specify.Get Property Info VIRetrieves the properties of a data file, channel group, or channel.Set Property VIDefines a property for a file, channel group, or channel. Wire data to the Value input to determine the polymorphic instance to use or manually select the instance.Get Property VIReturns the value of a property for a file, channel group, or channel. You must manually select the polymorphic instance you want to use.Merge Storage Refnums VIMerges two arrays of storage reference numbers into one larger array of refnums. This VI works properly only if the two sets of storage refnums are from the same data file. Wire data to either of the storage refnums inputs to determine the polymorphic instance to use or manually select the instance.Create Query Expression VICreates a query expression to use with the Execute Query Expression VI to search for objects that meet the condition you specify. Wire data to the value input to determine the polymorphic instance to use or manually select the instance.Merge Query Expressions VIMerges two query expressions. You can use the Create Query Expression VI to create query expressions that you want to merge.Execute Query Expression VIReturns data objects that meet the query expression.Refnum to ID VIReturns the ID for a data object.ID to RefnumReturns a refnum for an object you specify. Wire data to the storage refnum input to determine the polymorphic instance to use.Parent topic: Storage/DataPlugin
