Abstract

An I/O-abstracted configuration is defined for a field device that has not yet been assigned or allocated to communicate via a particular I/O device, and the field device (and optionally portions of the process control loop of which the field device is a part) is commissioned based on contents of its I/O-abstracted configuration. The field device's I/O-abstracted configuration is stored in an instance of a device placeholder object, which may be common to multiple types of devices and multiple types of I/O. A property of the device placeholder object may be exposed based on the value entered for another property, and the device placeholder object may store abstracted values as well as explicit or discrete values that are descriptive of the field device and its behavior. Upon I/O-assignment or allocation, values held in the device's I/O-abstracted configuration may be transferred to or otherwise synchronized with the device's as-built configuration.
