And even if the game gets tricky, there’s always a chance the cards will turn.

A dropped robot controller, everyday handling in harsh industrial conditions, or a damaged display – it takes very little for a faulty teach pendant to stop your line, delay maintenance and increase repair costs. Yet you can proactively protect FANUC, KUKA and ABB robot control panels with robust covers and protective films that prevent display damage.

Want to streamline production and keep consumption, downtime, or machine condition under control? Looking for a simple yet robust way to connect your machines with IT systems? We’ve put together a bundle for collecting, storing, and integrating machine data that stands out not only for its price but also for its completeness.

During the Christmas period, we remain available almost as usual. You can reach us on all working days between Christmas and New Year. Only on Friday, January 2nd, our company will be closed for operational reasons

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.

Power outages mean downtime, scrap, and data loss. That’s why we’re bringing a new line to the Czech market and to our online shop—products from the German manufacturer Bicker Elektronik. Their DC UPS units maintain 24 V (or 12 V), safely save data, and—where possible—restart devices. Bicker products come with a 3-year warranty. The devices also offer smart functions for system optimization and safety.

For efficient work with Horner panels (PLCs with integrated HMI), you need a reliable and intuitive programming tool. The Cscape software allows configuration of both the PLC and the integrated HMI within a single environment—and it’s free. Once again, we asked specialist Jaroslav Blažek (blaja.cz) to take a closer look at the software. You can find out how the installation and registration went in his review.

Horner PLCs with integrated HMI have not been part of our product range for long, but they are already attracting well-deserved attention. We asked industrial automation expert Jaroslav Blažek (blaja.cz) to take a closer look at them — especially in terms of functionality, intuitive operation, and practical deployment options. Find out how these Horner devices performed and what he has to say about them in the following review.

Horner PLCs with integrated HMI are new not only to our e-shop, but also to our market. We asked respected industrial automation specialist Jaroslav Blažek (blaja.cz) to explore all the functions and user-friendliness of these devices. You can find out whether he was satisfied and what it was like working with the Horner units in his review.

Kepware’s KEPServerEX software is well-known for its extensive library of communication OPC drivers for industrial devices. While drivers for protocols like Modbus or Siemens are commonly used in daily operations, there are several lesser-known yet highly practical drivers. We have selected 5 lesser-known KEPServerEX drivers worth your attention.

OPC Router is smart software that allows you to easily connect data from industrial devices to IT/OT systems without the need for programming. Everything is fast and automated, with clear visualisation showing all data flows in real time. You no longer need to purchase individual plug-ins (connectors) separately, as you can now purchase a convenient package containing the most commonly used ones. Alternatively, you can have all plug-ins and add-ons (extensions) in one licence at a great price with the "All in One" package.

Are you looking for a compact, powerful and easy-to-integrate solution for machine control or upgrading existing technology? We are pleased to introduce a new addition to our product range: panels from Horner Automation.

In the final part of our article series on the PROFIBUS analyzer, we will show, among other things, how to connect the analyzer to PROFIBUS as a Master, control Slave stations, adjust network speed (you’ve probably never seen PROFIBUS running at 9.6 kbps), and install and use plugins that extend the tool’s capabilities. Review by Jaroslav Blažek (blaja.cz).

Another part of the series on the ProfiTrace2 analyzer for PROFIBUS networks, where we’ll show what the most common faults look like and how and where they appear in the analyzer. This is where things really start to get interesting. At the end, there are also some videos where you can clearly see how the signal changes—for example during a short circuit on the line. The analyzer review was prepared by Jaroslav Blažek (blaja.cz).

PROFIBUS—a robust communication network found in thousands of industrial systems. It has been used for years and still plays an important role in automation. But what happens when a problem occurs? Is it really enough to watch the green LEDs on the peripherals and trust that everything is fine? Unfortunately not. That’s why we invite you to read Jaroslav Blažek’s reviews of the ProfiTrace2 tool.

The PROFIBUS industrial bus is highly tolerant and will forgive many faults. But if a critical fault occurs—or several small ones accumulate—you will definitely notice. That’s why this aging industrial network deserves attention. Even if faults on your network are still rare, they will gradually accumulate. What do our technicians recommend? What are their 10 tips for maintaining PROFIBUS?

The new version of the data connector focuses especially on management efficiency, increased security and better system monitoring. New features make everyday work with OPC Router easier and improve its deployment in large industrial environments. There are many improvements — what are the main ones?

Power failures are a problem in industrial environments. Sudden system shutdowns can lead to data loss, file corruption or even equipment failure. That's where the NODKA UPS Supercapacitor comes in. How long can the Supercapacitor keep a computer running and how does it control the shutdown of the computer in the event of a power failure? You'll see in the videos below.

The most frequent users of Ewon industrial routers are machine and equipment manufacturers. The remote access capability of these routers enables them to communicate with the control systems of the machines they manufacture and sell, even if they are on the other side of the world. In addition, Ewon Flexy makes it possible to collect data from machines and make it available to customers via visualisation. One of the companines that cleverly use all the benefits of these routers is the leading Czech engineering company ŽĎAS.

At FOXON, we will be using the Christmas holidays at the turn of the year to switch to a new ERP system. This will result in temporary restrictions in our operations. However, we are confident that due to planned production shutdowns and holidays during the holiday period, these restrictions will not have a significant impact on cooperation with our customers.

A good reason to upgrade to a higher version of KEPServerEX is always security, which has been improved in several areas in the latest version. Therefore, we recommend upgrading to the higher version of the software after testing. Other reasons include feature and device connectivity updates as well as fixes and enhancements, which you will find briefly in this article.

We have been selling NODKA panel PCs for over a year. Let's ask one of our satisfied customers, the company Kronospan, why it chose NODKA panel PCs and how it uses them.

Do you use one or more Talk2M free accounts? Have you found that this solution is no longer enough and that you need Talk2M light or Talk2M pro? This guide will show you:

• how to upgrade your existing Talk2M free account to Talk2M light or Talk2M pro,
• how to import Ewon devices from one or more Talk2M free accounts into the upgraded account,
• how to create a group of routers in the upgraded account and assign users to it, including access rights.

The Talk2M cloud service allows EWON router users to easily and securely connect to their devices/machines remotely via the Internet from anywhere in the world. Until now, two types of service have been available – Talk2M free and Talk2M pro. From 2 May 2024, a new, affordable account type – Talk2M light – will be available. In addition, the rules for the free account will change.

At the beginning of 2024 we introduced a new product from the German manufacturer of industrial modules W&T to the Czech market. Check out our short videos to see how easy it is to set up and use W&T sensors and digital and analogue inputs and outputs for data acquisition using OPC UA and MQTT communications. 

In 2023, we established cooperation with Nodka, a manufacturer of industrial computers, panel PCs and monitors, and it turned out to be a good choice. We successfully tested the products and then implemented them in full operation at our customers. Let us take a closer look at this innovation in our market, starting with computers.

The new version of OPC Router 5 brings some big changes. The biggest change is the user interface, which brings the user more comfort when working with the program and the ability to work in Linux, macOS, etc. There are also new options for creating user accounts, improvements in application performance optimization and many other improvements.

The rules for building PROFIBUS DP networks state that a maximum of 32 PROFIBUS DP stations can be connected to one segment. The second limitation is the length of the segment cabling, which is inversely proportional to the speed of the PROFIBUS network used. In addition to these rules, there is another rule of thumb that says that 32 stations in one segment means de facto 32 potential points of failure. Each PROFIBUS device has an impact on the quality of the network by its connection to the network. Therefore, reduce the number of PROFIBUS devices in a PROFIBUS segment to a lower number by using ProfiHub repeaters or multirepeaters. The result will be a maximally reinforced, reliable, functional and robust PROFIBUS network that will not be brought down by anything.

Unlike competitive products, PROCENTEC repeaters and multirepeaters have better results in galvanic separation of segments and also digitally smooth the messages between segments. An error in one segment will not move to the other segment, which unfortunately cannot be claimed 100% for all repeaters on the market. If you want quality repeaters and multirepeaters, choose PROCENTEC products. 

Wireless transmission via optics or radio waves? Optical transmission causes minimal delay and requires direct visibility of the optical modules. Wave transmission works at 869 MHz and 2.4 GHz and is useful where optics do not work. For a video demonstration of the German company Schildknecht's products, click HERE.

If you are in charge of several PROFIBUS networks and want to check their quality from time to time or troubleshoot problems that have already occurred in a particular PROFIBUS network, the ProfiTrace2 tester is a great tool for you. You connect to the PROFIBUS network and measure signal qualities, voltages, communication errors, presence of interference, etc. When the measurement is complete, you create a report and disconnect again. The tester can be left connected to the PROFIBUS network for longer periods of time, but requires a laptop to which it is connected via the USB port.

If you operate a PROFIBUS line that is critical to you and an unplanned failure of the PROFIBUS network is not desirable, then get permanent diagnostics via the ComBricks solution. You connect the device to the DIN rail, connect it to the PROFIBUS network, without the need to assign an address or change the PLC program. From the first moment of connection, the tester measures the PROFIBUS network 24/7 and provides comprehensive overviews of the network quality in clear tools. It alerts you in time to the first undesirable event such as lost stations, lost packets, corrupted messages, voltage drops, interference, etc.

For Ewon routers, we recommend upgrading to the latest firmware version. Firmware updates are usually released to implement new features, improve security and usability, or fix bugs. There are several ways to upgrade the firmware and each is designed for a different situation.

ComBricks is a unique solution that features user-friendly remote monitoring of PROFIBUS networks and thus provides you with an overview of their health. As part of prevention, ComBricks will alert you by email if any of these problems occur on your PROFIBUS network – repeats, lost stations, slaves requesting diagnostics, etc. All problems are saved to the internal memory and can then be reviewed via a web browser.

ComBricks doesn't require any special software installations on your PC. You only need to type your ComBricks' IP address into a web browser.

PROFIBUS connectors are part and parcel of every network. Their quality and ease of installation are factors that contribute enormously to a healthy network. We're the only company offering special Canon PROFIBUS connectors with multi-angle cable outlet (the connector's cable outlet can be at 35° or 90° to the device's PROFIBUS port). These connectors allow you to set the cable outlet direction to meet your needs. Apart from that, they feature screw terminals, which means that A and B wires are screwed in using terminal blocks. We sell connectors with PG port for the same price as those without it. We're in favour of PG port as it enables PROFIBUS diagnostics. That's why we actively encourage our customers to buy connectors with this port.
