Abstract:
A method for use in a process control system for generating structured control codes which control a subject system, said process control system having a user interface of a function block diagram editor including basic function block menus which represents a plurality of predetermined basic function blocks, said method comprising the steps of:providing input/output data of the subject system in the form of a 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 in block diagram form by using the input/output block menus and the basic function block menus on the user interface; andconverting the control algorithm to structured control codes,wherein the basic function block includes an arithmetic function block, a trigonometric function block, a combination function block, a comparison function block, a bit-shift function block, a selection function block, and a variable type conversion function block.
