Introduction to PLC Programming and Implementation (4)

4. PROGRAM ORGANIZATION AND IMPLEMENTATION

Organization is a key word when programming and implementing a control solution. The larger the project, the more organization is needed, especially when a group of people is involved.

In addition to organization, a successful control solution also depends on the ability to implement it. The programmer must understand the PLC control task and controlled devices, choose the correct equipment for the job (hardware and software), and understand the PLC system. Once these preliminary details are understood, the programmer can begin sketching the control program solution. The work performed during this time forms an important part of the system or project documentation. Documenting a system once it is installed and working is difficult, especially if you do not remember how you got it to work in the first place. Therefore, documenting the system throughout its development will pay off in the end.
