Managed Ethernet Switches as PROFINET IO
You can use either a managed or an unmanaged Ethernet switch for PROFINET. Of course, if downtime is expensive for you, you will easily justify using a managed switch. (See past post.) You can use an OPC-SNMP server to read information from a managed switch and display it and alarm it in an HMI. It’s…
Read MoreManaged or Unmanaged Switch for PROFINET
Should I use a managed switch or an unmanaged switch with PROFINET? Yes. Yes, you should use either a managed or an unmanaged Ethernet switch with PROFINET. An unmanaged switch has no built-in intelligence except to send incoming Ethernet frames out the right port – the port that the destination device is connected to. And…
Read MoreFive Things You Should Tell Your Boss about PROFINET
What should you tell your boss about PROFINET? Here’s the list, but the five things all come back to saving money. Maybe that’s why we often see PROFINET “accidentally” spelled PROFITNET. Legacy protection: you can update a system without doing a rip-and-replace of the existing fieldbus. Just use a PROFINET proxy to seamlessly integrate the…
Read MoreWhy use an IP-Address?
Did you catch the new White Paper we posted? If not, here it is: PROFINET for network geeks (and those who want to be). Done yet? TL;DR (it’s only four pages!): The White Paper discusses the seven-layer ISO/OSI Reference Model, as well as how in the Ethernet world, these seven layers collapse down into four. It…
Read MoreHanover Fair, News
Here are a couple news items from PI at Hanover Fair. PROFINET in Process PROFIBUS PA and PROFINET play well together, we are reminded. Our addition of functions such as CiR (Configuration in Run), Redundancy, Time synchronization, and Time stamping (Sequence of Events) and the proven standardized proxy solution for integrating fieldbus systems of any…
Read MorePROFINET Fuddy-Duddy
A fuddy-duddy is someone who is old-fashioned and conservative almost to the point of eccentricity or geekiness. I fail to see how old-fashioned and geekiness can be used in the same definition. But I just used “fuddy-duddy” because it sounds interesting and it contains “FUD.” FUD, you may recall, stands for Fear, Uncertainty, and Doubt.…
Read MoreContracted Security
Should securing your network follow the model of securing your plant? Most factory security guards that I’ve encountered don’t work for the company that owns the factory; they’re contracted. Should you contract securing your network? You probably contract at least some of your automation engineering to a System Integrator. Is this any different? This line…

PI (PROFIBUS and PROFINET International) has created a unique institution: the PI Competence Center (PICC). There are 50 of these around the world. And their existence and availability are reasons that PROFINET is a truly global phenomenon. The PICCs are there to provide support for the PROFINET and PROFIBUS networks. A user facing network questions…
