Quality Assurance

FDT Test and Certification

Background – FDT Specification I

All work together FDT Specification defines how products

from different manufacturer work together

Prove in practice The theoretical possibility must be proved

in practice

Demand for guarantee Customers require a maximum of

guarantee for the interaction of products from different vendors

Certification Certification of the products can give a

guarantee

Background – FDT Specification II

Tested independently Before a product gets the certification it

must be tested independently

Product matches specification The independent test checks if the

product matches with the specification in all points

Interoperability Interoperability is a major objective of

FDT

Background – Vendor test

Tests necessary■ Vendor specific tests are also necessary

Not recognized Sometimes errors can not be recognized by vendor specific

tests due to■ Different and wrong interpretation of the specification■ Incomplete or wrong implementation

Independent test These kind of errors should be found during an independent test

Tools to perform the independent tests

Background – Development support I

Verify The developer of a DTM or Frame application needs support to

check his DTM or Frame against the FDT specification. From early beginning on

The FDT conformity check should begin as soon as possible within the development process.

Logging The tools provides extensive logging capabilities.

Close to source code If there are errors in the software implementation, the developer

will be navigated near to their locations in the source code.

Test Scope

In scope DTM or Frame application fulfils the FDT Specification

Out of scope Functional tests of the DTM or the Device

Extendable The official test scripts can be extended by the manufacturer

to cover also product specific tests These tests are not relevant for certification tests (Semi-) automated software tests can be performed

Types of the Test

Good cases Test flow with variation of parameters and

variation of method calls, which are in scope of the FDT-Specification

Bad cases “Bad behavior” which is in scope of the

FDT-Specification, e.g. communication errors

Robustness cases Parameters or a sequence of method calls

will be used, which are not conform to the FDT-Specification

Types of the Test (Optional)

Style Guide Test Conformity test of GUI related attributes defined by the FDT specification

Certification Process

Certification Process - Details

At first a manufacturer develops a DTM or a frame application and puts these through extensive tests, potentially already making use of our test tools for in-house tests. Following this initial phase a manufacturer then arranges the conditions of the conformity test with the test laboratory.

Next, the test laboratory conducts the tests according to the rules laid down by the FDT Group and then issues a test report. The test report is then being given to the manufacturer. If in testing it turns out that there are still deviations from the conformity, the test laboratory will consult with the manufacturer in great detail. It is this consulting service that constitutes a real benefit for the manufacturer, because he now can eliminate the deficiency and resubmit the DTM for testing.

After a positive test the manufacturer can submit the test report to the certification office and apply for a certificate. Optionally the certified product can be listed on the FDT Group homepage.

Beyond Certification > Interoperability

Interoperability Test DTMs are being incorporated into different Frame

applications. Frame application will be tested with a number of DTMs

Interoperability Test 3 (22 suppliers) 7 frame applications 21 device DTMs 6 Communication DTMs HART, Profibus, FF All DTMs performed
