Systems and methods provide for programming a wireless device for an automation system. The system and methods include specifying commands that are to be preformed regarding function blocks that may be organized into an application on a wireless device. The function blocks may be maintained in a library by a control engine on the wireless device. The control engine receives commands related to function blocks, such as instantiating function blocks from the library or linking existing function blocks. The control application formed by the function blocks may be executed on the controller to provide an automation application.
