Abstract

This application discloses a method for interpreting and running an SFC program, including: determining the target SFC program; traversing the target SFC program to obtain all elements in the target SFC program and the logical relationship between elements; The logical relationship runs the program corresponding to each element in turn. In this application, there is no need to compile and download the SFC program to the controller for execution. Therefore, no matter how large the scale of the project is in this application, no more controllers are needed to support it. While reducing the complexity of the project, it not only reduces system maintenance The complexity also reduces the engineering cost.

Description

technical field [0001] The present application relates to the field of automatic control, in particular to a method and device for explaining and operating an SFC program. Background technique [0002] In the field of industrial control, especially the fine chemical industry, engineers often use Sequential Function Chart (Sequential Function Chart, SFC) program for hierarchical structure design when controlling the mass production of items, which can not only meet the requirements of high flexibility, but also improve equipment The utilization rate and production efficiency can be improved, and it can reduce the time to market of new products, ensure the consistency of product quality, and reduce maintenance costs. [0003] The current SFC program usually runs in the controller of the lower computer. The existing control method generally compiles the written SFC program into C code, and compiles it again to generate a binary bin file, and downloads it to the controller for e...
