COMMENT ADDING METHOD OF LADDER CHART GENERATION CAD SYSTEM FOR PROGRAMMABLE CONTROLLER

摘要

PROBLEM TO BE SOLVED: To eliminate the need to reinput and recorrect comments by inputting addresses and comments to a drawing on a hard sequence CAD side and generating a comment file for registration to a sequencer CAD. SOLUTION: A drawing number and a page number of a hard sequence(H/S) are accepted. When there are comment data on the H/S side, a comment TAB comment key is set and the data are added to an input table. When there are the input data of the comment key, a drawing number and a page number are taken out of the input table and H/S drawing data are read in and set in a memory. When there is comment information, the input data are extracted, a comment key is set, and the comment key of an address part corresponding to the comment key of a comment part is retrieved and written in a table for associative data generation while replacing an address TAB comment (Chinese character data). Then the table is sorted and its contents are set in an output file.
