CUSTOM APPLICATION ENVIRONMENT IN A PROCESS CONTROL DEVICE

摘要

Methods and apparatus are disclosed to provide a custom application space in a device controller. Example disclosed methods involve communicatively coupling a device controller to a host. The example host provisions the device controller and an automation device within the process control system. The example disclosed methods also involve installing a process control application into an application space in firmware of the device controller. The example process control application is to be provided by the host with permission data. The example disclosed methods also involve executing the process control application in the application space. The example process control application extends functionality of the device controller. The example disclosed methods also involve moderating access by the process control application to physical resources of the device controller. The example permission data defines which of the physical resources that the process control application has access.
