Abstract: PURPOSE: An apparatus and a method for generating a control program using a graphic are provided to reduce the development time by preventing a program error generation through an intuitive coding. CONSTITUTION: A function database(100) stores function information provided from a text, which represents a control program. A graphic user interface unit(110) outputs the function stored in the function database(100) as a graphical representation by the selection of a user and provides a way for representing the outputted function and a function interrelation as the graphical representation. A data storing unit(120) stores data inputted though the graphic user interface unit(110). A program converting unit(130) converts the data stored in the data storing unit(120) into a text control program. A file storing unit(140) stores the text control program converted by a file through the program converting unit(130).

Abstract: PURPOSE: A crane control system having an integral network is provided with an MMI system communicating with a central controller. CONSTITUTION: An MMI system(100) is provided to input control program, monitor input/output signal and data. A central controller(110) analyzes the inputted control program of the MMI system to control whole system in real time. A direct input/output device(130) is connected to the central controller by a bus. A network driver(120) is connected to the central controller to drive and control network. A remote input/output device is connected to the network driver. A PLC(140) is connected to the network driver and to a motor.

Abstract: PURPOSE: A method for controlling sequence is provided to improve the suitability by allowing each step of an SFC(Sequence Flow Control) to control the whole flow without using a separate scheduler. CONSTITUTION: A step of an SFC is made as an independent task which is multi-processed by a multiprocessing operating system(300). The task comprises a routine for receiving a token, a routine for performing a transition according to an input transient condition, a routine for performing a corresponding internal step operation, and a routine for transferring a token to a task corresponding to an output transient condition. Input/output transient information of each step and input/output step information of each transition are set(310). A task generated according to the input/output transient information and the input/output step information is performed(320).
