METHOD FOR EXCHANGING DATA BETWEEN ENGINEERING TOOLS OF AN ENGINEERING SYSTEM AND ENGINEERING SYSTEM FOR CARRYING OUT THE METHOD

摘要

The invention relates to a method for exchanging engineering data (RED) between independent engineering tools (ET1... ETx) of an engineering system (ESY) and an engineering system, wherein engineering associated with a project such as a production plant, switchgear or robot cell Data (ET1PD ... ETxPD) of each of the engineering tools (ET1 ... ETx) are stored in a data storage (SR, SPMR) associated with the engineering tool in a tool-specific data format and selected by a user, a System function (SF1 ... SFn) such as project management function, topology management function, variable exchange function or diagnostic function associated with engineering data (ET1D ... ETxD) of the engineering tools required for at least one Another of the engineering tools are of interest, using a conversion unit (ETC1 ... ETCx) converted into a standardized data format and stored in a standardized common data memory (CC). In order to optimize the exchange of engineering data at engineering time and to achieve a minimal redundancy without changing the existing data models of the engineering tools, it is provided that changes of the selected engineering system associated with a system function (SF1... SFn). Data (ET1D ... ETxD) of the individual engineering tools (ET1D ... ETxD) are continuously buffered in the standardized common data memory (CC) and, if necessary, read by one of the engineering tools (ET1 ... ETx) at any time and that for a temporary access to the entire engineering data (ET1PD ... ET1XPD) assigned to the project by a requesting engineering tool, a start of the providing engineering tool is executed.
