Learn how the retentive timer preserves accumulated time and supports reset, illustrating with a sample program, a time base of one second, and a comparison to a normal timer.
Solve assignment one by building a PLC program that maintains pressure between 90 and 110 psi, turning the pump on below 90 and off at 110, with run indicator lamp.
Watch a real-world, error-tolerant programming session that shows mistakes while building a four io project with two inputs and two outputs, including IO setup, bits, GSR, and basic control logic.
Explore building pump and indicator control with two rungs, one-shots, and timers, using start and stop delays tied to pressure thresholds such as below 90 psi and 110 psi.
Drive motorized conveyor to feed boxes into a filling station, using proximity and color-detection sensors to choose pecans or walnuts from hoppers, with a sonar level sensor stopping the fill.
Learn to implement a three-stage cycle for box handling using an integer counter, tracking bring, fill, and unload, with proximity switch, photo eyes, level switch, and one-shot actions.
Test and debug a PLC based conveyor system in an emulator, fix a one shot issue, and introduce an intermediate mode to stop the conveyor when the proximity switch closes.
Test and debug an automated conveyor system by running emulations, saving, reloading, and iterating mode logic to ensure hoppers and conveyors respond correctly to proximity, photo eyes, and level sensors.
Implement inventory logic for a scan-based system. Use string comparisons to map widget, doodad, and walkie part numbers and adjust quantities from incoming and outgoing values converted to ascii strings.
Control an automatic multi-position valve with a servo-driven cam and microswitches to detect home, fill, drain, and flush, driven by a host cycle with timing and a home reset.
Develop a servo control logic using trigger bits, cycle timers, and position checks to automate fill, drain, and flush sequences, with home and interrupt-driven cycle management.
As a PLC programmer, you will usually find yourself working alone, unsupported and with nobody to help you but Google. Your boss or client will tell you what they need, and the only thing they want to hear from you is, "Here it is." And when you deliver, it goes without saying that the expectation is - that it WORKS!
This is the course (always cheaper on PLC Dojo) the acclimates you to the real world. This isn't the classroom anymore; this is war! You vs the PLC.
In this course, we hit the ground RUNNING. I designed this course to build upon the theoretical training students received in "PLC Programming from Scratch" by taking that knowledge (plus a few new pieces) and constructing original ladder logic applications to solve everyday, industrial problems.
Using the Rockwell software RSLogix 500, RSLinx and RSLogix 500 Emulate, you will be given various descriptions / specifications for programs and then expected to write each one from scratch. After, I will walk everybody through my own approach to each problem step-by-step. Lastly, we'll run each project on the emulator and debug as required before moving on to the next section.
This course is 100% practical! It is expected and assumed that you got the theoretical in my previous PLC course, and as such, this course contains NO REFRESHERS. This is all new material! There ARE a few new instructions used in this course, and those will be properly introduced, but you should already know how to use blocks like XIC, XIO, OTE, ONS, SCP, JSR and etc.. Again - this is an INTERMEDIATE course. It has a PREREQUISITE course before it. Don't try to walk before you crawl and then get all sour and mad about it when you fall down.
Let me be clear: you WILL struggle in this course. That's the whole point. My first PLC course has a lot of group hugs, hand-holding, warm bottles of milk and hippie drum circles all in a safe, friendly, positive learning environment. This course is NOT like that. This is boot camp. This is you being thrown into the deep end of the swimming pool... with a shark. If you want to get frustrated, wrack your brain trying to solve hard problems and learn what it's like being a PLC programmer - this is your course! You'll come out of it better, faster and smarter. If you're not ready for that yet, take my first course.
What's covered in each of the five PLC courses I teach here and on my own PLC Dojo site?
PLC Fundamentals (Level 1) teaches you how to program with the focus on ladder logic, which is the most popular PLC programming language. The goal is to teach you everything you need to know to make a PLC do what you want it to do. You are also given all the software necessary to both CREATE and RUN your own programs live - right on your own computer.
Applied Logic (Level 2) forces you to take what you've learned and solve problem after progressively harder problem unassisted. You get a spec and are told simply: "Make it work, and don't progress until you have." After, you get to watch me solve each one as well. By the end, you don't just know how to program - you are a PROGRAMMER.
Process Visualization (Level 3) gives you both knowledge and experience in FIVE different HMI / SCADA development environments. By the end, you've created several COMPLETE visualization (screen) projects that you can actually run on your own computer (and SHOW PEOPLE in an interview) with no additional hardware.
IEC Paradigms (Level 4) is only for the heavyweights. This course teaches you how to program using all five IEC programming languages (plus one more) in multiple environments. There are projects as well, so by the end, you have seen it all and DONE it all as well. There won't be anything anybody can show you that you won't already be familiar with.
TIA Portal Master Project (Level 5) is the culmination of everything. In that course, you'll program an entire power plant using all five PLC programming languages (in PARALLEL!) with a full HMI. It's a massive and complex project that really showcases your talents in an interview!
