Workers™ provides a framework API and support tools that you can use to develop Queued Message Handler (QMH)-based LabVIEW applications.
Workers is a software add-on for LabVIEW. It includes the Create/Add Worker tool that helps you create and integrate new or existing QMH templates into existing Workers applications. You can view the chronological flow of messages sent between QMH templates with the Workers Debugger tool. The add-on provides a Priority Queue to send messages between QMH templates and a Hierarchy View that you can use to view the call chain of all the statically linked and dynamically loaded QMH templates in an application. Additionally, Workers supports built-in error handling and error logging.
