PARALLEL INPUT SUPPORTING METHOD OF CIRCUIT ELEMENT IN LADDER SCHEMATIC PROGRAMMING DEVICE OF PLC

摘要

PROBLEM TO BE SOLVED: To enable even an operator unfamiliar to operation to easily insert a desired circuit element in a gap between existing circuits in a parallel connection mode even in a display state in which a series of circuit lines is closely arranged.;SOLUTION: Only when cursor movement to one circuit constituting a ladder circuit diagram from the other circuit is determined, a blank line is automatically inserted to the lower adjacent circuit line of the one circuit line on condition that the lower adjacent circuit line is not a blank line.;COPYRIGHT: (C)2011,JPO&INPIT
