Title:
CIRCUIT CREATION PROCESSING METHOD FOR SEQUENCE LADDER CIRCUIT DESIGN BACK-UP SYSTEM
Document Type and Number:
Japanese Patent JPH05341814
Kind Code:
A
Abstract:
PURPOSE:To improve the designing efficiency of a sequence ladder circuit by attaining a routine processing method for creation of the ladder circuit which controls the drive of an output device. CONSTITUTION:A basic unit ladder circuit of such a type necessary for securing the safety, the operability, etc., of a machine device and an operation unit ladder circuit which is used in common for the drive control of an output device are stored in a standard data circuit data file 53 as the standard circuit patterns. Thus a unit ladder circuit is designed as necessary in accordance with the assignment state of the input or output device or a time chart and based on the file 53. Then the operation unit ladder circuits designed based on the IC assignment data and the time chart are standardized. Then the circuit designing efficiency is improved together with facilitation of the maintenance.
