PROFI Mnemonics

I’m a big fan of mnemonics. A mnemonic, /nɛˈmɑːnɪk/ (the first “m” is silent) device, or memory device, is any learning technique that aids information retention in the human memory per Wikipedia. In school, you may have learned a mnemonic to remember the Great Lakes: HOMES, Huron, Ontario, Michigan, Erie, Superior. I learned the resistor…

Where’s My GSD File?

GSD files have been needed for a long time, first for PROFIBUS, and now for PROFINET. Our usual comparison is to printer drivers. A GSD file tells the software system what features, I/O, alarms, and diagnostic capabilities a device has. It resides in the engineering tool, not in the device itself. A printer driver is…

Secure Your Network!

Your network is not secure! Whether you have all the security in place that’s possible or have not even thought about security – your network is not secure! Sadly, no network can be 100% secure. The best that you can hope for is to make it very difficult to hack. Let’s start at one of…

Show Me the Money

Show Me the Money, or justifying an Industrial Internet of Things project with PROFINET because we like the technology. Dilbert has been known to say, “We’re technology driven.”  But that does not resonate with the owners and their managers – whether the “owners” are stockholders or private individuals. Those folks’ mantra will be some form…

Motor Diagnostics

PROFINET excels at device to controller communications. But not all communications needs to go to the controller – there is some data it just doesn’t need. There are many articles in the…

Cloud versus Fog

If the Jeopardy answer is “Cloud, Fog, or Edge,” the question is “Where all can you do analytics?” We rejoice in the PROFINET of Things with its Data Access, Uptime, and Openness, but the Industrial Internet of Things is really about analytics. PROFINET is an enabler. A very important enabler, but still an enabler. The…

PROFINET Independence Day

It’s Independence Day in the USA, the Fourth of July. PROFINET connection coming up, but first… “Independence Day” always reminds me of the movie (the original one, where a virus created on a Mac laptop can infect an alien operating system) and the old joke “Daddy, does Canada have a fourth of July?

We’re Number One

PI does not get to say that PROFINET is the best Industrial Ethernet; the market gets to say that. Which is why I was amused to see a technology that’s in fifth place in the market tout why they’re better than all the other Industrial Ethernets. The market has assigned them their place and it’s…

Digital Twins

Along with Cyber-Physical Systems, Big Data, Cloud, Analytics, and other Industrie 4.0 and Industrial Internet of Things buzzwords is the concept of Digital Twin. Maybe Digital Twin is from Industrie 4.0 and not IIoT? Here is a definition of Digital Twin from Wikipedia: “Digital twins refer to computerized companions of physical assets that can be…
