Although you learned best practices in writing a safe and reliable PLC program in the PLC training foundation phase, you will want to move on to more PLC programming training. While most will guess, you learn more about PLC programming by doing real PLC programming projects, that can be a slow (and costly when mistakes are made) process. A little bit quicker and less risky method of gaining experience PLC programming can be by learning through experimentation writing programs on a training PLC and/or with a PLC simulation software like the one we recommend below. But even this has it limits as to how far you can go.
Another method of learning PLC programming that should be part of any best practice PLC programming objective is to read and study existing programs of real processes. But before you do, learn best practices like detailed in GAMP®5 guide, study 21 CFR Part 11 and IEC 25010 paying special attention to maintainability quality. Then as you study PLC programs written by others, perform a static analysis (verification testing) on their programs as that process will greatly improve your PLC programming skills. Like the PLC ladder logic example we link to below, the more PLC programs you study, the more you will start to see common programming methods and best practices. It is analogues to a teacher becoming a professor by studying more books. Books are knowledge gained by the author, working PLC programs are knowledge gained by other PLC programmers. You will no doubt see things in the PLC programs written by others that you previously learned are not best practice, but you will also learn some new methods and best practices of accomplishing real world task.
[Book mark this page because soon we will start to add PLC programming training videos that share more best practices.]
