Abstract
Abstract Structured control codes which control a subject system are generated in a process control system having a user interface of a function block diagram editor including basic function block menus which represent a plurality of predetermined basic function blocks. The structured control codes are generated by the steps of: providing input/output data of the subject system in the form of database; retrieving the input/output data of the subject system; providing the input/output data as an input/output block menu on the user interface of the function block diagram editor; building a control algorithm by using the input/output block menus and the basic function block menus on the user interface; and converting the control algorithm to structured control codes.
