Can alternative graphical representations be used?
Software tools can use alternative graphical, textual or tabular representations, so long as accompanying documentation specifies an unambiguous mapping to the graphical elements and associated textual syntax defined in IEC 61499-1. • How can a function block respond to faults and exceptions? In the IEC 61499 model, faults and exceptions are modeled as event outputs and associated data outputs of service interface function blocks. These outputs can be connected to appropriate event inputs and associated data inputs of any function blocks which must respond to the fault or exception, e.g., by changing their operational modes. • How is the loading and starting of applications managed? Software tools for this purpose will take as input a system configuration and generate sequences of commands to management function blocks to perform loading and starting of applications, either locally or remotely via communication function blocks. • How can “trend” and “view” objects be created?
