Industrial Wireless: What to Consider

Lots has been written in this space about using industrial wireless with PROFINET. This is mostly the ‘what’; this post is to address the ‘how’. “How do I implement industrial wireless in a PROFINET network?” Just to recap, while wireless is… Read more »




Wireless – It’s More Prevalent than You Thought

PROFINET can be connected wirelessly as easily as it can be connected with wires.  Of the four kinds of wireless (see previous post), this post is about wireless in discrete automation.  Moreover, it’s about places where wireless has already been… Read more »


Four kinds of wireless

PROFIBUS and PROFINET are involved in three of the four kinds of wireless. (Yes, wireless is not one monolithic thing: Wireless or Wireless.) My take on the four kinds: Long-distance like to RTUs Process instrument networks like WirelessHART (PI cooperated… Read more »


Wireless Distance to Nashville

In Nashville, I did not answer a question adequately about the ranges for various wireless technologies according to a comment on one Course Evaluation.  Let me remedy that here: The expected distance for the various IEEE802.11 variants (a, b, g,… Read more »


Wireless or Wireless

One of my pet peeves is lumping all wireless types together and treating them as one.  Wireless is not one monolithic thing. I see four types of wireless in industrial automation: 1. Backhaul (as I think ISA characterizes it).  Typically… Read more »


Technology Updates (Hanover Fair 2009 Report 3)

There was news of progress in a number of technology areas: IO-Link, wireless, PROFIBUS, and PROFINET. IO-Link products are appearing more rapidly.  IO-Link is not a fieldbus, but allows digital communications over the device’s cable.  This led me to characterize… Read more »


PROFINET in Austin

There were 45 of us in Austin for the PROFINET one-day training class.  Not many compared to the previous day’s PROFIBUS class in Pittsburgh with 102, but still a very engaged group posing lots of questions for us. So many… Read more »
