Abstract
A data construct set and method for use with an industrial process which is controlled according to execution code wherein a processor running the code generates requests to mechanical resources to cause the resources to perform the process, the construct enabling generation of diagnostic code interspersed within the execution code which, when an event is to occur, indicates the event to occur, the invention also including status based diagnostics generally and methods of using the data construct set for generating both execution code and status based diagnostics.
Claims15
A development tool for use with a processor and a display, the processor for running execution code for controlling control mechanism sets which in turn control resources to perform an industrial process, the tool for generating execution code which includes a status based diagnostic agent which indicates progression of the execution code via the display, the tool comprising:
- for each mechanism set:a control assembly (CA) encapsulating at least:
- an execution logic specification specifying resource requests to the mechanism sets, at least a sub-set of the requests including sequential request events;
- and
- a diagnostic specification specifying events corresponding to at least a sub-set of the execution logic requests;
- whereby CA instances can be instantiated such that the combined instantiated CAs specify information required to generate execution code including status based diagnostics indicating the next event expected to occur, for the industrial process.
A method for use with a processor and an editor, the processor running execution code to control control mechanism sets which in turn control resources which perform an industrial process, the processor controlling by providing requests to the mechanism sets, at least a sub-set of requests including request events, the method for providing a programming tool to be used in conjunction with the editor to specify execution code including status based diagnostics and including the steps of, for each mechanism set:
- encapsulating in a control assembly (CA):
- an execution logic specification pecifying resource requests to the mechanism sets, at least a sub-set of the requests including sequential request events;
- and
- a diagnostic specification pecifying events corresponding to at least a sub-set of the resource requests.
