Where Is the Edge of the Industrial Internet?

I’ve recently read a number of blog posts and articles talking about the Edge of the Industrial Internet of Things, including Vibhoosh Gupta’s blog post titled “Industrial Edge Node: The iPhone of Industry.” They made me think about where the edge really is.  I’ve heard “edge” defined differently by different people. This is my attempt…

What is PROFINET?

PROFINET is a mechanism to exchange data between controllers and devices. Controllers could be PLCs, DCSs, or PACs. (Programmable Logic Controllers, Distributed Control Systems, or Programmable Automation Controllers.) Devices could be I/O blocks, vision systems, RFID readers, drives, process instruments, proxies, or even other controllers. PROFINET exchanges data quickly and deterministically. Required speeds vary depending…

Complementing PROFINET

“Nice job, PROFINET.”  “Way to be deterministic there PROFINET.” No, not complimenting PROFINET, complementing PROFINET. PROFINET is a great backbone for I/O, controllers, vision systems, drives, and more.  But it isn’t all things to all devices.  There are times and places where PROFINET is not the logical network to use.  Fortunately, PROFINET integrates complementary networks…

Ask the instructor: PROFINET Developer Training

Kyle McMillan is a guest blogger and the PROFINET Certification lead at the PROFI Interface Center – a PI-accredited Test Lab. Recently, we began offering a formal Developer Training course to complement our PROFINET Certified Network Engineer curriculum.  Carl invited me here to explain why. It’s simple: I’m lazy.  Really, I am; I like to…

Developing a PROFINET Product – Member Resources

We at PI North America and PI Competence Centers like the PROFI Interface Center are happy to help anyone who is developing a PROFINET product.  But we can offer more resources to members. In my last post I outlined some resources that are available to anyone. This post is about the resources that are available…

Developing a PROFINET Product

There are so many choices of ways to add PROFINET to an automation device that it is difficult to know where to start.  Where to start depends on: Existing design Type of product Quantities expected Time to market needed For a product with an existing Ethernet controller, a PROFINET software stack can be added.  This…

The Data-Driven Factory

Being in the business of moving data with PROFINET, references to the data-driven factory* appeal to me.  Appealing as that is, it’s an incomplete story.  Like a word-driven blog post.  Random words collected do not a blog post make. Random data collected does not a factory drive. Data is the raw material. Turning it into…

PROFINET – Show Me the Money

PROFINET can help you justify your project as these features have financial rewards: Feature: proxies. Benefit: Maps legacy networks into PROFINET using an open standard. The money: no need to rip and replace.  Leave your current network intact and add a proxy to integrate the devices into a new PROFINET-based controller. Gain the benefits of…

PROFINET – There’s a Lot to Know

As frequent PROFIblog aficionados probably know, I’m a big fan of the Course Evaluations from our free PROFINET one-day training classes.  In Louisville last week the results were typical: the course length was right, the training manual was good, and the instructors were great, so said the filled in circles on the machine-scored form.  But…

PROFINET of Things: Openness

A major driving force of the Industrial Internet of Things and Industrie 4.0 is the reliance on open standards. PROFINET devices are manufactured according to the PROFINET specification (IEC 61158).  PROFINET is Ethernet, IEEE 802.3.  Many other standards also come into play – standards from IEC, IEEE, NAMUR, and IETF (Internet Engineering task Force): IEC…
