Abstract
During commissioning activities of a process plant, a device placeholder object that stores an I/O-abstracted configuration of a particular field device within the plant is created and stored in a device in the back-end environment of the plant and a further configuration file is stored in or for the particular field device in the field equipment environment of the plant. The device placeholder object, which will eventually be associated with the particular field device, and the field device configuration file are used to perform separate commissioning activities in each of these plant environments before the field devices are configured to communicate with a process controller via a particular I/O network within the plant. Thereafter, a binding application performs a discovery process to detect the I/O communication path through which each field device is connected to the back-end environment. The discovery process traverses through the I/O network as built, and autosenses the devices within the I/O network until this process discovers a device placeholder object or a configuration file for a particular field device. The binding application then determines if the information withi…
