摘要： A computer-based tool, in the form of a computer system and method, for designing, constructing and interacting with any system containing or comprising concurrent asychronous processes, such as a factory operation. In the system according to the invention a variety of development and execution tools are supported. The invention features a highly visual user presentation of a control system, including structure, specification, and operation, offering a user an interactive capability for rapid design, modification, and exploration of the operating characteristics of a control system comprising asynchronous processes. The invention captures a representation of the system (RS) that is equivalent to the actual system (AS)--rather than a simulation of the actual system. This allows the invention to perform tests and modification on RS instead of AS, yet get accurate results. RS and AS are equivalent because AS is generated directly from RS by an automated process. Effectively, pressing a button in the RS environment can "create" the AS version or any selected portion of it, by "downloading" a translation of the RS version that can be executed by a programmable processor in the AS environment. Information can flow both ways between AS and RS. That AS and RS can interact is important. This allows RS to "take on" the "state" of AS whenever desired, through an "uploading" procedure, thereby reflecting accurately the condition of AS at a specific point in time.
