Is IEC 61499 a “stand-alone” standard? No.
• Communication profiles which define standard communication function blocks and their mapping to standard open communication services such as those under development in IEC Project 1158 (Fieldbus). • Standard programming languages such as those defined in IEC 61131-3 for the specification of algorithms in basic function block types. • Standardized function block types and guidelines for their application in specific domains, such as the process control function blocks under development by IEC SC65C/WG7.
