Abstract:
A computer-implemented control program tracker for displaying an improved graphical representation of a control program's behavior as it performs runtime control program operations, comprising:a runtime engine monitor for monitoring the runtime performance of control program operations by said control program;a memory data structure accessed by said runtime engine for storing a representation of said control program as a plurality of blocks, each block corresponding to at least one of said control program operations, and for storing block state information associated with the runtime performance of said control program operations;a graphical display engine for generating spatially arranged graphical objects corresponding to said plurality of blocks and arranged to convey information about the relationship of said control program operations;a tracking module that accesses said memory data structure and communicates with said graphical display engine to selectively impart different visual representations to said graphical objects to reflect the runtime performance of said control program, wherein said visual representation is indicative of at least three different states of the runtime performance of said control program.
