Overview

The class reviews De Morgan’s laws and challenging Boolean-algebra homework, then explains the equipment and software setup for a Siemens PLC project. It compares Siemens with Allen-Bradley, traces the adoption of Siemens S7-1200 and S7-1500 controllers, and outlines how students can install TIA Portal V20 and obtain a one-year professional license.

Key takeaways

The PLC project requires a Windows 10 or Windows 11 computer, and MacBooks are not suitable for the specified Siemens software setup.
De Morgan’s laws are central to the upcoming quiz: push complements inward by switching AND and OR, and eliminate double complements.
Knowing both Allen-Bradley and Siemens PLCs can improve job prospects, while the S7-1200 provides an inexpensive, capable entry point to Siemens controls.
Siemens version 20 is needed for newer hardware; version 16 remains available in labs, but the course is skipping versions 17 through 19.
Students can obtain a one-year Siemens professional license through Automation License Manager using an Ethernet connection, following a 21-day TIA Portal trial.

Chapters

0:00 Windows Computer Requirements and Missing Lab Cables

PLC project software requires Windows 10 or Windows 11; MacBooks are not compatible with the required setup.
Students without access to a suitable Windows computer should email the instructor, especially if their group has three or fewer members and no computer.
Camera connections use turquoise, blue, and black cables; missing black cables should be returned rather than moved between rooms.

3:27 Applying De Morgan’s Laws to Boolean Homework

The class works through difficult homework expressions by simplifying complements from the outermost grouping toward individual terms.
De Morgan transformations switch OR to AND and AND to OR while complementing each term, with double complements canceling.
Problems 4.10 and 4.11 receive attention, and the instructor warns that De Morgan questions will appear on the quiz.

17:52 PLC Textbook and Recorded Chapter Resources

The PLC textbook was largely written between 2015 and 2020, with an extensive set of chapter videos recorded during COVID.
Students can find the recordings through the YouTube channel’s Playlists section under the PLC series.
The recorded material covers chapters 1 through 21; chapter 11 is described as the most listened-to chapter.

21:29 Allen-Bradley and Siemens: PLC Industry Context

Allen-Bradley became dominant in the United States by the early 1980s after competing with Modicon, while older Modicon equipment persisted because plants were reluctant to replace working controllers.
The instructor describes Siemens as a growing U.S. competitor and the dominant PLC player worldwide, making knowledge of both Siemens and Allen-Bradley valuable in job interviews.
After Siemens introduced the S7-1200 and S7-1500 controllers, the department acquired them around 2011 to 2012; the S7-1200 offers substantial capability at a low-cost entry level.

27:30 TIA Portal Versions 16 and 20 for the Rubik’s Cube Project

Siemens software changes made initial setup and login difficult for the Rubik’s Cube project, even though PLC programming itself is relatively straightforward once configured.
Version 16 remains installed in lab rooms, while room 2350 also has version 20 to support newer Siemens hardware that version 16 cannot handle.
The department is moving directly from version 16 to version 20 rather than adopting versions 17, 18, and 19.

30:57 Professional Licenses and the ALM Transfer Process

The instructor has 80 Siemens TIA Portal V20 professional licenses from an allocation of 100, with about 20 already used.
Students can receive a one-year professional license by connecting computers with Ethernet and using Siemens Automation License Manager on both systems.
Allen-Bradley software is an option for students who already have access through an employer, but the instructor cannot provide support or licenses for it.

33:00 Finding the Rubik’s Cube Guide and Downloading TIA Portal

The course site’s Courses section contains the Rubik’s Cube material, including a text titled for weekly projects and the setup instructions beginning on page two.
Download TIA Portal V20 from Siemens’ official website rather than a third-party site; the software provides a 21-day trial.
Students can use the Automation License Manager transfer to replace the trial with a one-year license; the project exercises reuse PLC assignments from the instructor’s original textbook.
