Mechanical and electrical hardware
I mentioned last week that I am working on what I believe is the first truly advanced non-platform-specific book on PLC Programming. My friend Tony over on Factory Automation Software Blog has reviewed some books that come the closest, but …
In last weeks’ post, I discussed acquiring data using a PLC to capture values from an analog card. I showed some fairly straightforward methods of capturing data using FIFO methods, averaging data values, and how some of the ladder logic …

Todays post is in response to a request by Quy Phan, who I met a couple of weeks ago while teaching for Automation Training in San Diego. He is having some problems with some existing equipment concerning noise on his …
I’ve written a few posts on controls platforms, notably on Allen-Bradley, Automation Direct/Koyo, and Siemens. A couple of friends have written guest posts on Idec and Panasonic. I am still hoping to get some contributors to write articles on GE, …
Last week I posted a fairly straightforward question at the end of my post on PLC Scanning. I then shared the post on Linked In as well as on my company’s Facebook page. One reason I share these posts on …
In my last post on PLC Memory Organization, I mentioned that I had not really covered how scanning actually works in a programmable controller. This is certainly a topic that needs to be discussed for an understanding of PLC programming, …
One of the first decisions that needs to be made when designing a PLC system is memory allocation and organization. In the early years of the PLC memory came at a premium… 1K (one kilobyte) of memory for the program …
Today’s article is a guest post by TiMotion, an electric linear actuator manufacturer. ********************** Get The Essential Facts About Actuators Don’t make the mistake of buying a robot when a simple actuator will do. Robots have become the “go-to” tool …
Today’s article is a guest post by National Metal Fabricators. ******************************************** Robotic Automation for Welding It’s difficult to inspect a welded joint. Two metal pieces may appear fused together, but without destructive testing, it’s hard to be sure. That’s why …
Automation Direct has written a new post on the history of the PLC that you might find interesting. It can be found HERE and covers the early years of PLC development. It mostly discusses Dick Morley and the founding of …
