Choose the Network First

In the Atlanta PROFINET one-day training class, someone was asking about using PROFINET with a controller that does not natively support it.  The unusual part of this is that only one controller maker does not support PROFINET natively (you have… Read more »


PROFINET vs EtherNet/IP

First, a disclaimer, and no surprise: I may be slightly biased in favor of PROFINET. That said, I believe the following facts to be actual facts. While this post could expand to thousands of words, this will be the Readers… Read more »


PROFINET Can Multicast. But Why Do It?

There was a recent blog post over at Schneider called “It’s all about choice: EtherNet/IP and unicast and multicast traffic.” You can follow the link to read the whole thing but the gist of it is: “PROFINET people think EtherNet/IP… Read more »

The EtherNet/IP FUD-sicle – Melted Again

The EtherNet/IP folks just can’t stop talking about PROFINET… and just can’t stop getting it wrong.  It’s almost like they’re deliberately misrepresenting PROFINET.  The latest example is in the Industrial Ethernet Book article “Working successful motion control via standard Ethernet.”… Read more »


What is a Node?

One of the questions that came up in the market share discussion over at Gary Mintchell’s Feed Forward blog (Ethernet in Manufacturing and Automation) centered on the definition of a node.  Thanks to a telephone conversation with the author of… Read more »


Ethernet Is the Industrial Network of the Future

My blog post last month about market shares triggered Gary Mintchell to comment on his Feed Forward blog.  That started a discussion that is worth following: Ethernet in Manufacturing and Automation. –Carl Henning



Multitasking on Industrial Ethernet

Automation World has an interesting article in the February issue and online: “Ethernet Protocols’ Flexibility A Boost For Manufacturing.”  It manages to mention five different Industrial Ethernet protocols but then goes on to focus on PROFINET and Ethernet/IP.  This is… Read more »
