Here’s my inputs and thanks for the outputs.  That’s the Industrial Internet of Things. When I read articles about the Internet of Things, I find them…

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.

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.

Complementing PROFINET

“Nice job, PROFINET.”  “Way to be deterministic there PROFINET.” No, not complimenting PROFINET, complementing PROFINET.

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…
