Safety, Security, and Rodney Dangerfield

As I get caught up on my reading, I’ve uncovered an article with many PTO members quoted: “Safe-motion choices” in the March issue of Control Engineering.  PROFIsafe brings the most experience to the “safety on the regular fieldbus” game.  As with a regular fieldbus, safety-on-the-fieldbus brings the installation advantage of easier wiring and, more importantly,…

PROFINET in Motion

There’s an article from Automation World, “Ethernet-based Motion Hot and Real-time,” that briefly describes the various Ethernet-based motion control protocols – emphasis on the word briefly.  For a more complete explanation of how PROFINET does motion control, download the PROFINET booklet.  PROFINET is the one technology that does all the things that need doing in…

The first one, “High-tech Profibus system succeeds in the outback” does cover SEX – sodium ethyl xanthate, a lead collector used in mining.  This application story is from PTO…

Well, the airplane seat wasn’t big enough to comfortably use the computer.  So, I settled for listening to Gary Mintchell’s podcast and then opened a novel.  But Saturday afternoon’s low scoring Arizona Diamondbacks’ game gave me time to write.  Herewith, some recommended reading on fieldbuses, wireless, and Industrial Ethernet.  Plus some “pot-stirring”? Fieldbuses “Fieldbus in…

IO-Link, HART for discrete?

IO-Link is a point-to-point wiring system intended for smart sensors and actuators.  It communicates over the discrete device’s wires.  This reminds me of HART in the process space where communication is superimposed over the 4-20mA signal wires.  And similar to HART, you can use an IO-Link device in a standard system and a non-IO-Link device…

Why Use a Fieldbus?

“Why Use a Fieldbus?” The number one reason people don’t use a fieldbus is that they don’t know about them. Most likely they haven’t been told of the benefits. This White Paper remedies that!
