This playbook is the 4th in my PLC Programming series. It is an exhaustive collection of my tutorials and demo videos on how to work with Allen Bradley’s Point IO 1734 hardware. First, you will be introduced to this hardware component from Rockwell Automation. Next, you will learn how to connect to it from a network. With my demo videos, you will also learn how to wire a SICK sensor into a Point IO input and test the hardware in Studio 5000. You will find this book and the accompanying demo videos very helpful if you are an electrician, an instrumentation technician, a manufacturing operator, an automation professional or engineer looking to progress their career or level up their knowledge of Point IO digital input wiring and testing, and to acquire advanced PLC programming skills. There are 11 chapters in this book which are accompanied with 9 in-depth HD demo videos that you can download. These videos simplify everything you need to understand, and help you speed up your learning of Point IO Hardware programming and integration. There is also a link in this book for you to download my PLC programs (codes) for your revision. I start with an overview of the Point IO modules, and then move on to IP addressing, web server, and power supply overview. Then I proceed to Point IO integration into Studio 5000, including how to create the Point IO definition within the CompactLogix 1769-L24ER-QB1B PLC and validating the communication. Finally, I take a special look at a Point IO real panel example. This is a Point IO panel used for a plant control which I commissioned myself few months ago. So, after studying this book and the demo videos, you should develop a hands-on approach to the programming and integration of Point IO into Studio 5000 Rockwell Environment, and be able to use it in real world industrial applications.
