While I still have a lot of "web design / admin" work left to do on the TAB and TAS websites, I'm also beginning the process of creating my third generation of video courses.

I'm actually quite excited about the opportunity to create several PLC courses simultaneous, focusing on a modular approach so the courses can be updated and kept fresh for years to come.

As I start this journey, the first question that comes to mind is, "what is the best programmable controller to learn on?"

Obviously this will depend on what is installed at where you work, or where you want to work.

But if you're learning on your own dime, that's not always an option, as high end programmable controllers like the ControlLogix or S7-1500 (and the software that programs them) can cost an arm and a leg.

That in mind, for those who will be funding their own education here's some things to consider:

First, what vendor is used in your plant or where you want to work?

While all PLCs are similar, the process of actually programming them is quite different, so if possible try to choose to learn on the same vendor you'll be using in the field.

Second, what is the cost of the software?

Some programming packages can run $3,000 or more, so if you want to actually program as part of your learning, this is going to be a consideration.

With those two things in mind, here's a simple cheat sheet I've put together for new users to consider:

Want to learn: -> Lowest Cost SW Option

PLC-5, SLC-500, MicroLogix: -> RSLogix Micro Lite

Cost - Free

While RSLogix Micro Lite only supports the MicroLogix 1000 and 1100, learning with it will also help you learn how to use RSLogix 5 and 500.

CompactLogix, ControlLogix: -> Studio5000 Mini

Cost ~$800, 30 Day Demo Available, 7 Day Grace period

While there's no free version of Studio 5000, you're local distributor can get you a 30 day trial license to use. And installing the software on a new PC or VM will net you a 7 day grace period trial.

Keep in mind the Mini is Ladder only for the Compact only, so if you're asking for a 30 day trial, ask for either Lite (Compact) or Full (Compact and Control) editions to try out.

Micro800: -> CCW

Cost: Free

While not the most popular PLC, the Micro800 does support Ladder, Function Block, and Structured Text, so it's a good all around option for learning on since the Micro810 and 820 PLC is so inexpensive.

S7-1200: -> TIA Portal 21 Day demo

The S7-1200 is the small PLC from Siemens which programs nearly identically to the larger S7-1500, and the good news is anyone can download a 21 day demo copy of the software free of charge right from Siemens website.

Well, that's what I have so far on this topic - if you have any suggestions or comments I invite you to post them below!

Sincerely,

Shawn
