METHOD AND FRAMEWORK SYSTEM FOR CONVERTING PLC BASED CONTROL CODE TO A GENERAL PROGRAM CODE USING XML INTERFACE

摘要

PURPOSE: A method for converting a PLC(programmable logic circuit) based control code into universal program code using an XML(eXtensible Markup Language) interface and framework system are provided to promote the reusability and flexibility of a program using an XML element table. CONSTITUTION: A PLC open code creation unit(110) creates a PLC open code using a function block diagram language. An XML interface creation unit(120) creates an XML interface using the PLC open code. An universal code creation unit(130) creates a universal program code using the XML interface. The XML interface creation unit includes a configuration element classification unit, an XML element table unit, an attribution allocation unit, and an interface conversion unit.
