Software Architecture for Simultaneous Process Control and Software Development/Modification

摘要

A software architecture is described that allows modification of some application code sections while the remainder of the application continues executing. This architecture facilitates long term testing and process control because the overall process need not be stopped and restarted to allow modifications or additions to the software. A working implementation using National Instruments LabVIEW sub-panel and shared variable features is described as an example. This architecture is particularly useful where the application is running in an "executable" rather than in a "development" environment as recompiling the entire program is not necessary after the modification.
