This part of IEC 61 499 defines rules for the development of compliance profiles, which specify the features of IEC 61 499-1 and 61 499-2 to be implemented in order to promote the following attributes of IEC 61 499-based systems, devices and software tools:
• interoperability of devices from multiple suppliers;
• portability of software between software tools of multiple suppliers; and
• configurability of devices from multiple vendors by software tools of multiple suppliers.
These attributes are illustrated in Figure 1 .
