SECTION 4

Writing and Inputting the Program

This section explains the basic steps and concepts involved in writing a basic ladder diagram program, inputting the pro-
gram into memory, and executing it. It introduces the instructions that are used to build the basic structure of the ladder
diagram and control its execution. The entire set of instructions used in programming is described in
