An industrial integrated development environment (IDE) supports decoupled development of industrial control programs without requiring the programs to be initially bound to a specific industrial controller. The IDE system allows industrial control programs to be defined as smart objects within an industrial control project. These smart objects can be created without an initial binding to an industrial controller, and can subsequently be assigned to selected industrial controllers after development of the control programs is complete, or while program development is in progress. A smart object can be reused and deployed to multiple industrial controllers, providing a simple means to implement common control functionality on multiple different automation systems. To allow for deployment of smart objects to selected controllers, the IDE system supports creation of a control project having a one-to-many relationship with industrial controllers, such that multiple controllers can be defined within a single project.
