METHOD FOR MODIFYING AND CHANGING OPERATION OF FUNCTIONAL BLOCK USED IN PROCESS CONTROL SYSTEM AND DYNAMIC MODIFIER FUNCTIONAL BLOCK

摘要

PROBLEM TO BE SOLVED: To provide a method for modifying and changing operation of a functional block to be used in a process control system, dynamic modifier functional block capable of such modification, and a functional block. SOLUTION: The functional block is stored to a machine readable medium so as to be used by the process control system and includes a basic functional block for having a machine execute an algorithm related to the process control system and at least one attribute in the basic functional block for having the machine delete or instantiate at least one dynamic modifier functional block.
