scope:

This International Standard specifies requirements for service diagnostic software to be implemented in products that incorporate a digital interface. It does not specify requirements for carrying out remote diagnosis or for manufacturer-dependent software.

The SDI requires the use of a controller (exclusive controller or general-purpose controller/PC) into which service diagnostic software can be loaded. Part of this controller software should be standardized while another part of this controller software is manufacturer-/product-related.

To reach a common approach in servicing all products from all manufacturers it is necessary to standardize specific items in the products (device under test (DUT)) as well as in the diagnostic software on the controller.

The SDI is based upon the ECHONET specification because this interface will be used in most future products. The use of this connection and existing communication protocols enable implementation in products at low cost and gives maximum flexibility and efficiency.

The SDI consists of

• the specific hardware and software requirements of the DUT;

• the specific requirements of the controller:

- the service software;

- an ECHONET interface (to be built in if not already present);

• the connection between the controller and the DUT.

This specification is the minimal specification necessary to be able to carry out computerized diagnosis and covers the standardized software of the controller as well as the standardized software and provisions in the DUT.
