If you develop or buy a system using a standard protocol you want to be sure it complies with the standard. KEMA has facilities for testing IEC protocol implementations. The testing involves a number of elements, including interoperability testing and conformance testing.
Interoperability
Interoperability testing entails establishing that data exchange is possible and evaluating application integration between systems from different vendors. If systems are able to interoperate, the test result is positive. However, if two systems are able to interoperate, it does not follow that the exchange of data between them must comply with the specifications of the applicable standard.
Compliancy
Conformance testing is therefore needed to establish whether a vendor’s implementation is compliant. To test compliance, the vendor’s system is connected to a reference system maintained by a test organization. Procedures for conformance testing are integral to certain standards (IEC 60870-6, 61850 and DLMS). When testing compliance with these standards, a test organization follows these procedures. KEMA’s Protocol Competence and Test Center is the number one test organization for IEC protocols. KEMA was the first independent (level A) test organization authorized by the UCA Users Group to perform the official IEC 61850 conformance tests and issue UCA certificates.
KEMA is well equipped for conformance testing. First we draw up the test plan based on the test procedures and the customer-specific requirements. We use an advanced conformance test system in combination with a protocol analyzer to test whether a specific device meets the international standard. The test will reveal any interpretation problems and bugs in the software at an early stage (before implementation on the customer’s site). Energy companies often require that a product passes a conformance test before they will proceed to purchase. So having a KEMA or UCA certificate also gives a manufacturer a competitive advantage.
In KEMA’s experience, more than 90 per cent of devices fail the first test. It has been proven that using certified products significantly reduces communication problems when a device enters service.For more information, please contact us.
