This document discusses designing control processes using flowchart techniques. It begins by defining the basic components of a flowchart like blocks, arrows, and decision points. It then provides examples of implementing simple sequential processes as flowcharts, including a water tank filling process. The document explains two methods for representing flowcharts in ladder logic programs using block logic or sequence bits. Finally, it presents a example of using flowcharts and high-level instructions to control the movement of a cart system.
