Owning Palette: Advanced Storage VIs

Requires: Base Development System (Windows)

Merges 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.

Use the pull-down menu to select an instance of this VI.

Merge Storage Refnums (Channel)

storage refnums (channel) 1 specifies the channels to merge. Wire the storage refnums output of the Read Data VI to this input.
storage refnums (channel) 2 specifies the channels to merge. Wire the storage refnums output of the Read Data VI to this input.
operation specifies the condition that joins storage refnums (channel) 1 and storage refnums (channel) 2.

0AND—Combines all channels that are included in both storage refnums (channel) 1 and storage refnums (channel) 2.
1OR—Combines all channels from storage refnums (channel) 1 and storage refnums (channel) 2.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
storage refnums (channel) returns the channels that meet the operation condition.
error out contains error information. This output provides standard error out functionality.

Merge Storage Refnums (Channel group)

storage refnums (channel group) 1 specifies the channel groups to merge. Wire the storage refnums output of the Read Data VI to this input.
storage refnums (channel group) 2 specifies the channel groups to merge. Wire the storage refnums output of the Read Data VI to this input.
operation specifies the condition that joins storage refnums (channel group) 1 and storage refnums (channel group) 2.

0AND—Combines all channel groups that are included in both storage refnums (channel group) 1 and storage refnums (channel group) 2.
1OR—Combines all channel groups from storage refnums (channel group) 1 and storage refnums (channel group) 2.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
storage refnums (channel group) returns the channel groups that meet the operation condition.
error out contains error information. This output provides standard error out functionality.
