Training agenda
The first day focuses on theoretical fundamentals, common issues, and initial cable and PROFINET network measurements.
The second day is mainly dedicated to practical diagnostics, measurements, and data analysis from real operational scenarios. Participants work with real measurements, diagnostic tools, and simulated faults. You will practice troubleshooting, measuring communication quality, and configuring network components.
The training includes real-life examples based on more than 18 years of FOXON experience in industrial network diagnostics and service.
Each participant has their own PC equipped with a PROFINET analyzer and a tester for measuring PROFINET cables.
What you will take away
After completing the training, you will be able to:
- Design, manage, and diagnose PROFINET networks
- Identify and resolve communication issues
- Measure and analyze network quality using professional tools
- Optimize communication parameters for reliable and stable operation
You will gain a deep understanding of how PROFINET truly works in practice and the ability to quickly respond to failures and proactively improve network reliability.
Who should attend
The training is intended for anyone working with PROFINET industrial networks, especially:
- Maintenance technicians and service engineers
- PLC programmers and system integrators
- Maintenance managers
- Electrical designers and automation engineers
involved in design, configuration, or maintenance of communication networks
Many participants recommend this training also for their design colleagues, as many issues originate already during the network design phase.
Training format
- Duration: 2 days (8:30–16:00 including breaks and lunch)
- Format: on-site training for max. 8 participants
- Each participant has their own PC workstation
- The trainer uses an interactive smart board for explanations and diagrams
- Training takes place at the modern FOXON Academy
Training location
FOXON ACADEMY Liberec
- FOXON s.r.o., Česká 615/25, Liberec, Czech Republic
- Training room no. 1
- Free parking on-site. Free EV charging available.
Training at your site
Upon agreement, we can also deliver the training directly at your facility. This option is often more convenient, especially for teams located further from Liberec.
However, based on our experience, training outside a dedicated environment may be disrupted by operational activities (calls, production interventions), which can affect participants’ focus and overall effectiveness.
A training room with a projector and screen is required. We can provide our own equipment if needed.
A major advantage of on-site training is the ability to include practical measurements and demonstrations directly on your production equipment.

About the Trainer
My name is Jaromír Peterka, and I teach people how to truly understand industrial networks so they actually work reliably.
For nearly 20 years, I have been working with industrial communications, especially PROFINET and PROFIBUS, which I’ve experienced firsthand in real production environments through diagnostics, troubleshooting, and preventive measurements.
In my training sessions, I don’t teach textbook theory. I share insights from thousands of real-world problems encountered in manufacturing plants.
I have developed my own training methodology, thanks to which participants:
- understand how networks really work
- see typical errors and their real impact firsthand
- learn how to systematically identify root causes of problems
- gain practical procedures they can apply immediately
The training also includes specially designed setups where participants can test network behavior, diagnostics, and real-life scenarios themselves.
The goal is not just to complete a training course. The goal is to leave with confidence, knowing exactly what to do when a network in production fails.

From Practice: At De & Co, They Can Find a PROFINET Fault in Just a Few Minutes
De & Co Hranice s.r.o. supplies production lines and robotic workstations for various industrial sectors. As the company gradually moved from smaller machines to large automated lines, the complexity of its communication networks increased as well. This created a need to diagnose PROFINET and at the same time connect securely and remotely to equipment already operating at customer sites. What technologies help their technicians do that?
The 3 Biggest Killers of the PROFINET Industrial Network
Our engineers perform diagnostics of industrial networks in hundreds of manufacturing companies. They travel across the country to find the causes of failures. We have asked them what problems they have most frequently diagnosed in customers' PROFINET networks recently. What have they told us?
Case Study: PROFINET at Magna Powertrain Under Control
Magna Powertrain lacked sufficient visibility and detail about PROFINET communication on production lines running 24/7. With ongoing digitalization and data collection from production, they no longer wanted to troubleshoot outages by “trial and error.” They wanted to quickly identify the root cause of issues or prevent them altogether, see the live topology, keep event logs, and monitor whether errors were accumulating anywhere.

NEW: Network diagnostics from EUR 304
Your network, too, could be on the verge of a “heart attack” without you even knowing it. Yet you can have its health checked from as little as EUR 304. And within 50 km of Liberec, we do not charge any travel costs. At the same time, we are expanding our services to cover additional network types. We measure and repair PROFINET, PROFIBUS, CAN, DeviceNet, EtherCAT, Ethernet, ASi and Wi-Fi.
Which switch for PROFINET networks?
Is it advisable to use cheap unmanageable switches for a few crowns or is it worth paying extra and buying manageable switches? Should I save money on buying switches for the production line or should I buy a quality PROFINET switch?
How to use PROFINET network testers correctly?
Carrying out successful PROFINET network diagnostics can be a challenge – we know that from our own experience. FOXON has been involved with PROFINET diagnostics, repairs and commissioning since 2010. Our portfolio includes testers for active as well as passive PROFINET diagnostics. We have extensive experience working with these testers. Sign up for one of our PROFINET training courses to learn how to use them. We'll be happy to share our expertise with you.
