This part of IEC 61499 defines requirements for software tools to support the followingsystems engineering tasks enumerated in Clause 1 of IEC 61499-1:– the specification of function block types;– the functional specification of resource types and device types;– the specification, analysis, and validation of distributed IPMCSs;– the configuration, implementation, operation, and maintenance of distributed IPMCSs;– the exchange of information among software tools.It is assumed that such software tools may be used in the context of an Engineering SupportSystem (ESS) as described in Clause C.1 of IEC 61499-1.It is beyond the scope of this part of IEC 61499 to specify the entire life cycle of industrialprocessmeasurement and control systems (IPMCSs), or the entire set of tasks and activitiesrequired to support an IPCMS over its life cycle. However, other standards which do specifysuch tasks and activities may extend or modify the requirements specified in this Part.
