This is also known as the development of an algorithm. A set of guidelines should be followed during program organization and implementation in order to develop an organized system.

Approach guidelines apply to two major types of projects: new applications and modernizations of existing equipment. Flow charting can be used to plan a program after a written description has been developed.

A flowchart is a pictorial representation of the process that records, analyzes, and communicates information, as well as defines the sequence of the process.

PLC Program Examples

Logic gates or contact symbology are used to implement the logic sequences in a control program. Certain parts of the system should be left hardwired for safety reasons. To program the PLC, the devices must be programmed in the same logic sequence as they are in the hardwired circuit see Figure 3. Therefore, the stop push button will be programmed as an examine-ON instruction a normally open PLC contact in series with the start push button, which is also programmed as an examine-ON instruction.

If the start push button is pressed, output will turn ON , sealing the start push button and turning the motor ON through the starter.
