Good morning Locals!
Late last week I decided to start reviewing books on Amazon on PLCs.
Why? Well, even though I've been at this since 1990, I'm very aware of the fact that I will never know everything, and that there will always be more to learn :-)
And I figured seven years after my initial kickstarter to create my first course, PLC Basics, it was time to broaden my horizons and see how PLC Book authors are teaching the masses about programmable controllers.
The first set of books I'm going to review are books free with Kindle Unlimited, since I already had an subscription as I'm a huge consumer of Space Opera and litRPG ebooks.
If all goes as planned, I'll have my first review up today on "Introduction to Programmable Logix Controllers and Ladder Logic" by Nule & Vishwakarma (link https://amzn.to/3fkb2hX)
In short, for $3 (or free with Kindle Unlimited) it does a good job of providing a no-nonsense introduction to PLCs, but has two flaws:
Needs an editorial pass for typos and awkward sentences -my guess is English in not the author's native tongue.
It really doesn't cover the market leader in the USA: Allen-Bradley, and makes some poor assumptions like times and counters have accumulates that are limited to 32767. Only true, if you're using old SLC-500s/PLC-5s/MicroLogixs from the 80's and 90's :-)
That said, I hope you all have a great week and thanks to our supporters for their continued support!
We take a first look at the Moxa EDS-2005-EL Ethernet Switch in this episode of The Automation Minute. To learn more about it, check out the below links:

I have a question that a more seasoned programmer probably doesn't have any trouble with but, I am having issues uploading a program from a 1769-L33ER PLC that is using Studio5000 Logix Designer V23. I can see the PLC on WhoActive and the RS Linx Classic and even am able to see the Driver Diagnostics for the PLC, however, the program never uploads. I am at a loss and am hoping you can help me. Thank you in advance for your assistance. I have attached a screen shot from RSLinx Classic; let me know if you would like anything else.
Good morning everyone!
Hope your week is off to a great start :-) I wanted to kick the week off by asking everyone who their favorite automation vendors are?
I ask because I want to be sure I reach out to all of them about having them on my show.
For reference, this a list of vendors who've come on this year:
See anyone you use that's missing?
Would you like to see any of these folks come back on?
Thanks in advance!
