1、Concept V2.6Lesson 6 Objectives:After completing this lesson, the learner will be able to:Describe the difference between Located and Unlocated Variables.State the rules for Variable namingUse the Variable Editor to create and or delete Variables. Lesson OverviewConcept Software uses the idea of nam

2、ed Variables and Constants in its programming structure in order to contain global data that needs to be passed between objects. The use of these named Variables eliminates the need to physically join objects together through the use of links. This lesson will explain Variables and Data Types, the n

8、 address.Implemented in the code, so its faster than a located variable.Located:Tag name with a hardware address. (State RAM.)Not implemented in the code, so its not as fast as a unlocated variable.Constants:Used to define value to a tagname, e.g., Hi_Temp = 103.7They cannot be located.Concept V2.6C
