- Updated2025-07-30
- 2 minute(s) read
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.

Inputs/Outputs
storage refnums (channel group) 2
—
storage refnums (channel group) 2 specifies the channel groups to merge. Wire the storage refnums output of the Read Data VI to this input.
storage refnums (channel group) 1
—
storage refnums (channel group) 1 specifies the channel groups to merge. Wire the storage refnums output of the Read Data VI to this input.
operation
—
operation specifies the condition that joins storage refnums (channel group) 1 and storage refnums (channel group) 2.
error in (no error)
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
storage refnums (channel group)
—
storage refnums (channel group) returns the channel groups that meet the operation condition.
error out
—
error out contains error information. This output provides standard error out functionality. |
