Open publisher page 2 citations

Abstract

This paper designs a table class which can be used to edit PLC ladder diagram, and successfully develops software using C++ language. The main advantages of the software are as follows: the size of table cell occupied by the ladder diagram device unit can be set arbitrarily; the number of devices has no restriction; the parameters of PLC device unit can be directly set on ladder diagram; the software is intuitionistic in expressing application of complex PLC ladder diagram.
