How to Create Flowcharts and Output Sequences for PLC Programming

A combination of logic gates and contact symbology.

Flowcharting is an approach used to plan a program after a detailed written description has been created. A flowchart is an illustration that documents, analyses, and communicates information. It also describes the operational process in a sequence. The flowchart shown in Figure 2 is a simple example. The chart shows a simple flowchart. Each step … Read more

Program Organization and Implementation for PLC Programming

Electromechanical relay circuit diagram

When programming or implementing a control system, organization is key. A larger project will require more organization, especially if there are multiple people involved. A successful control solution is not only about organization. It also requires the ability to implement it. Programmers must be able to understand the PLC control task, the controlled devices and … Read more
