1 results about "Function block diagram" patented technology

A method, apparatus, and storage medium for generating function diagrams (FDM) for a DCS system include: converting a Point of Unit (POU) configured in a controller project into an XML file; obtaining function block symbols created and labeled with pins in a graphical editing software interface; wherein the function block symbols correspond one-to-one with the function blocks in the XML file; after the function diagram is generated, real-time data of the pins on the corresponding function blocks is obtained from the DCS system using the graphical editing software and the pin labels, and displayed on the pins of the corresponding function block symbols; obtaining the input and output connection relationships of each component from the obtained XML file; and based on the obtained function block symbols, the input and output connection relationships of each component, performing logical connections between the components in the POU to generate the function diagram corresponding to the POU. This embodiment enables intuitive visualization of control logic, significantly improving the efficiency of system status understanding and fault location speed.
