RT Worker Convert

Workers Tools Menu

The RT Worker Convert tool allows you to convert a Worker's Main VI between its reentrant (Main.vi) and non-reentrant (Main NR.vi) forms.

By default (for non-RT targets), a Worker's Main VI is reentrant, allowing you to load and run multiple instances of a Worker within the same application. However, for development on NI real-time (RT) targets such as a Compact RIO, it is often preferred to develop using non-reentrant Worker Main VIs (Main NR.vi) so that debugging of the Workers Main VI is possible in LabVIEW.

The RT Worker Convert tool allows you to convert a Main.vi to and from Main NR.vi.

RT Worker Convert tool

When you open this tool, you will see the left list show Workers on your target with Main.vi's. The right list will show Workers on your target with Main NR.vi's.

Selecting one or more Workers in either list (mutually exclusive) and then pressing the Convert to (Main VI) button will replace the Worker's Main.vi with a Main NR.vi (or vice versa).

You can use a Worker with a Main NR.vi the same way you would a Worker with a Main.vi but note that because the VI is non-reentrant, you cannot run multiple instances of a Worker with a Main NR.vi.
