Abstract
A system, method, and an apparatus related to a standardized interface to separate new functions from the primary features of the DTM. This can circumvent the need for modification of the DTM when new functions are desired to be added. This can prevent the necessity of regression testing for existing functions in the DTM, and prevent risk of degradation of performance of the DTM after addition of the new functions. Consequently, by reducing the testing time, development time of upgrades to DTMs can be shortened and a lower cost can be achieved.
Claims9
A system comprising:
- a field device;
- a Device Type Manager (DTM) host for communicating with the field device, the DTM host comprising a host business logic, a function adapter, and a function provider;
- a function to be added to or modified in the DTM host;
- and
- a function configuration database, the function configuration database comprising a list of available functions,
- wherein:
- the DTM host separates the function to be added to or modified in the DTM host from primary functions of the DTM host,
- the function provider communicates with the function configuration database to look up the function, and
- the function adapter is configured to operate the function to be added to or modified in the DTM host with the host business logic.
An apparatus comprising:
- a Device Type Manager (DTM) host that communicates with at least one field device, the DTM host comprising:
- a host business logic;
- a function adapter;
- and
- a function provider,
- wherein:
- the DTM host separates a function to be added to or modified in the DTM host from primary functions of the DTM host,
- the function provider is configured to communicate with a function configuration database, the function configuration database comprising a list of available functions, and
- the function adapter is configured to operate the function to be added to or modified in the DTM host with the host business logic.
