Description

You've made PLCs do simple things, but now you need to optimize processes based on data you're collecting. Where does the data go? How can you access that data from memory efficiently? In this course, instructor Zara Khalil explains the details of data storage, how it interacts with input and output (I/O), and how you can approach memory structures. Zara introduces you to the different software and PLC controllers from Rockwell automation, as well as two different memory structures: rack based systems and tag based systems. She goes into more detail on rack based systems, including details on how these systems handle data files, a demo of LogixPro, and information on I/O address format. Zara concludes with more detailed information on tag based systems, including global and local tags, the address format you need to use in tag based systems, base and alias tags, and more.

Instructor's Courses

Am an Engineering Instructor and a passionate educator for both Post Secondary Education level and in STEM for young generation ,I am an M.Eng graduate ، Electrical and Computer Engineering Masters . I am currently working as Embedded Systems Developer/Coordinator at McMaster University at the W Booth School of Engineering Practice and Technology. While also enjoying working & creating courses on LinkedIn learning as Content Author-[In]structor (Check out my courses here, related to PLC, SCADA, Arduino Programming, IoT) : https://www.linkedin.com/learning/instructors/zahraa-khalil I love and thrive on volunteering , I have been volunteering ever since mid-school , one of my wonderful experience is with IEEE WIE (Women in Engineering) since 2014 , and was a Canada Central Area Chair for 2019-2020. I also enjoy volunteering in local events/workshops in teaching programming and STEM to young generation Outside Education & Engineering , you would find me enjoying jigsaw puzzles, painting ,plants ,and as an AD in film sets.
