A field device management system communicates with a smart device using a device description written in a communication protocol associated with the smart device and accesses data pertaining to a conventional or non-smart field device using a device description written in conformance with the smart device communication protocol. The field device management system uses the device description for the conventional device to initially request certain data pertaining to the conventional device from a user and then stores this data in a memory for future access. |

DETAILED DESCRIPTION This invention provides a method of accounting for and incorporating data pertaining to conventional field devices as well as smart field devices in a field device management system.
More particularly, this invention relates to a method of using device descriptions for conventional devices to allow management systems to account for conventional field devices in the same manner as these systems account for smart field devices.
According to one aspect of this invention, a method of supporting a conventional device for use with a management system that is capable of interacting with a smart device provides a device description (DD) for the conventional device.
This device description is written in accordance with the device communication protocol associated with that smart device and, preferably, specifies a plurality of categories of information pertaining to the conventional device including, for example, device-specific description information, methods to be implemented on the conventional device and user interface information.
The method uses the device description for the conventional device to ascertain data pertaining to at least one of the specified categories of information, stores the ascertained data in a memory and then accesses the stored data using the device description for the conventional device.
According to another aspect of this invention, a system adapted to access data pertaining to a smart device and a conventional device includes a device description for the conventional device.
This device description is written in conformance with a communication protocol associated with a smart device and, preferably, specifies a plurality of categories of information associated with the conventional device.
The system also includes a memory which stores data pertaining to a portion of the specified information and is programmed to access the stored data using the device description for the conventional device.
The system may also include programming for communicating with the smart device using a device description associated with the smart device
