Title:
PROGRAMMING DEVICE FOR PROGRAMMABLE CONTROLLER
Document Type and Number:
Japanese Patent JPH05189012
Kind Code:
A
Abstract:
PURPOSE:To automatically generate a ladder program by providing a ladder circuit component registering means and a ladder program generating means. CONSTITUTION:When the ladder circuit component registering means 301 registers a ladder circuit as a component, ladder circuit component data 305 are generated. When the ladder program generating means 311 sets the internal specifications of the ladder program, ladder program definition data 315 are generated. Then when ladder program generating operation is performed, the frame of the ladder program 321 defined by the generating means 311 is generated and the ladder circuit which is registered as the component is put therein. Then register numbers corresponding to symbol names in input/output registers used in the ladder circuit are taken out of the ladder program definition data 315, and are set in corresponding register number areas in the ladder circuit. Further, when plural circuits are set in the ladder program definition data 315, the same process is repeated as many times as the set circuits.
