12.5 Equipment Certification

The MDIS interface shall be certified at an OPC Foundation Certification Test Laboratory on a product basis. Any major release of the product shall be recertified. Recertification can also be required if there are any changes to the standard or test cases defined by MDIS. The certification documentation shall include

a list of valid MDIS Profiles and optional ConformanceUnits for which the vendor equipment is certified,
vendor equipment information used for testing,
equipment architecture and configuration used for testing during the certification process.

Extensions or aggregate Objects added during a project do not need to be recertified.
