I/O Specify Node Plug-In VI (Embedded Targets)
Use the I/O Specify Node VI if you want to have Elemental I/O Nodes whose type is determined at edit time, as opposed to when you define the I/O through the Elemental I/O Wizard.
If you have multiple I/O Node Implementation VIs, you must include an I/O Specify Node VI to determine which one to use. If you have an I/O Implementation VI for reading and an I/O Implementation VI for writing with different data types, you must include an I/O Specify Node VI. These VIs run at edit time on the host computer.
The VI returns the type of the I/O Node, which is either the return type for Elemental I/O Nodes configured to read or the input type for Elemental I/O Nodes configured to write. If you use this VI, you must include an I/O Node Implementation VI for each type returned.
