Title:
SEQUENCE CONTROLLER HAVING INPUT AND OUTPUT ADDRESS ALTERATION FUNCTION
Document Type and Number:
Japanese Patent JPS5585911
Kind Code:
A
Abstract:
PURPOSE:To enable to restart the operation in a short time, by enabling to correct the sequence program in a short time and replacing the input and output elements connected to the input and output terminals in disuse. CONSTITUTION:To the first and second address setters 22, 23, the input and output address before reconnection and that after reconnection are respectively set, and the push button switch SW10 is operated. Then, the correction of program caused by reconnection is made. Thus, it is not necessary to seek the sequence program for rewrite where it is stored in the program memory 10, and even if a number of sequence programs for rewrite are present, all the sequence program can be corrected with one operation and the correction of program caused by the reconnection of the input and output element can be made in a short time. Thus, if specific input and output terminals are disused due to the failure of the input and output circuit, the operation can be restarted in a short time only with the reconnection of specific input and output elements.
