distributed control IEC61499
The method of IEC 61499 compliant device implementation with the National Instruments LabVIEW is proposed. The work focuses on these aspects of the tasks of the event generation and dispatching, which have no direct counterparts in the G language. A mapping of all the IEC 61499 concepts onto the G language concepts is described. Because of the limited multithreading support in LV (multithreading is possible but a number of parallel threads is fixed at the stage of the program development and compilation) it is needed to fit all the IEC 61499 defined functionalities in a fixed number of threads. A FIFO queue based dispatching algorithm is implemented, similar to the one used in the C++FBRT implementation. The ultimate objective of the work is the development of the FBLV run-time environment, which converts the LabVIEW compatible industry grade hardware into the IEC 61499 compliant device.
