Many of those who start with PLC programming are faced with the challenge of deciphering code written by someone else. In fact, most PLC programming jobs will require you to work with existing code rather than write it from scratch. This task creates a challenge for novice PLC programmers as the interface in RSLogix 500 as well as RSLogix 5000 is unlike any other. Therefore, it’s easy to become frustrated trying to figure out where a certain tag is being used, how it ties into the logic and why it’s being used in certain places.
Learn how to create a new FactoryTalk View ME application, transfer it to a terminal, retrieve it from the same, and establish communications to an Allen Bradley CompactLogix PLC 1769-L24ER-QB1B.
The six operators play an important role in structured text programming in numerous applications. They're used for scaling analog signals, computing ratios, updating counters, converting between different constants and much more. In this tutorial, we will go over the operators mentioned above and create a few basic examples which would utilize them in a real PLC program. Lastly, we will go over the importance of parenthesis when it comes to the order of operation. It's not something that you'd normally worry about in ladder logic and is therefore an important point to understand when you're migrating to structured text.
Learn how to work with photoelectric sensors, understand the basics, how to wire them, how to tie them into various PLCs and field devices and lastly how to troubleshoot them.
The best way to learn PLC programming is to get hands-on experience. However, as many are trying to learn how to program these devices before landing a job, it becomes crucial to invest in your own hardware in order to accelerate the learning process. That being said, a PLC programmer will face three challenges when it comes to building an effective PLC trainer.
