PROFINET Proxies and Gateways

Migrating from a Fieldbus or other industrial Ethernet to PROFINET is a common challenge. Every automation system is specialized in some way, and specialized components may not “speak” PROFINET. To move data from the specialized systems up to the PROFINET network, you have to add an interpreter to the network: A Proxy or a Gateway.…

PROFIBUS to PROFINET: Migration strategies

Migration Approaches PROFINET leverages PROFIBUS technologies to ensure a smooth and cost-effective migration between them. Depending on the factory state and current network technology there are two migration approaches: Greenfield and Brownfield installation Greenfield Installation: Nonexistent network in the first place, i.e. new branch in the factory. New factories won’t require migration, but new branches…

PROFINET Cables: Fiber Optics

Fiber optic cables offer specific benefits over copper. They are usually implemented in areas with electromagnetic interference or significant ground potential differences. Fiber optic connections can completely remove problems caused by electromagnetic interference and ground equalization currents flowing in copper cable shields/screens. Some benefits of optical fibers over copper cables are: Optical fiber cables usually…

PROFINET Cables: Copper

A PROFINET network is built on standard IEEE 802.3 Ethernet. Due to challenging environments on the factory floor, most users opt for rugged industrial Ethernet cables when building an industrial network. Even though wireless access points are becoming more popular, most of today’s network connections are wired and require cabling. Depending on the application, industrial cables…

PROFI Mnemonics

I’m a big fan of mnemonics. A mnemonic, /nɛˈmɑːnɪk/ (the first “m” is silent) device, or memory device, is any learning technique that aids information retention in the human memory per Wikipedia. In school, you may have learned a mnemonic to remember the Great Lakes: HOMES, Huron, Ontario, Michigan, Erie, Superior. I learned the resistor…

Where’s My GSD File?

GSD files have been needed for a long time, first for PROFIBUS, and now for PROFINET. Our usual comparison is to printer drivers. A GSD file tells the software system what features, I/O, alarms, and diagnostic capabilities a device has. It resides in the engineering tool, not in the device itself. A printer driver is…

Secure Your Network!

Your network is not secure! Whether you have all the security in place that’s possible or have not even thought about security – your network is not secure! Sadly, no network can be 100% secure. The best that you can hope for is to make it very difficult to hack. Let’s start at one of…
