Abstract
A method and system of the subject invention provides for the extension of a device description file of a field device. The device description file is loaded on a field device, the field device is put into operation with the device description file in a fieldbus system, and an extension file is loaded on the field device during the operation of the field device. The extension file contains only concrete objects.
Claims20
A method for the extension of a device description file of a field device comprising:
- loading a device description file on a field device,
- putting the field device with the device description file into operation in a fieldbus system, and
- loading an extension file on the field device during operation of the field device, the extension file including only concrete objects, and wherein the concrete objects each comprise at least one specified parameter name, one specified data type, and one specified access type, and wherein the device description file is managed in an object dictionary of the field device, and wherein, using the extension file, the object dictionary is dynamically extended by the concrete objects at runtime.
A system comprising:
- a fieldbus system having at least one field device;
- and
- the system being configured to load a device description file on the field device, to put the field device with the device description file into operation in the fieldbus system, and to load an extension file on the field device during operation of the field device, and wherein the extension file only includes concrete objects, and wherein the concrete objects each comprise at least one specified parameter name, one specified data type, and one specified access type, and wherein the device description file is managed in an object dictionary of the field device, and wherein, using the extension file, the object dictionary is dynamically extended by the concrete objects at runtime.
