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?

In his review, Jaroslav Blažek (blaja.cz) focused on the UPS Supercapacitor from the manufacturer NODKA. Did it protect a connected device during a power outage as it should have? And for how long did it supply the device with power? Find out in the video below.

¿Utiliza una o varias cuentas Talk2M free? ¿Ha comprobado que esta solución ya no es suficiente y necesita Talk2M light o Talk2M pro? En esta guía le mostraremos:

• cómo actualizar su cuenta Talk2M free existente a Talk2M light o Talk2M pro,
• cómo importar dispositivos Ewon desde una o varias cuentas Talk2M free a la cuenta actualizada,
• cómo crear un grupo de routers en la cuenta actualizada y asignarle usuarios, incluidos los derechos de acceso.

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.

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. For more information on PROFINET network basics training, diagnostics and repair, 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.

Are you using Ewon Cosy or Flexy routers for remote access and wondering which Talk2M remote access service is right for you? We've put together some arguments to help you decide.

Ewon industrial routers are rightly one of the world's most widely used solutions for remote management of PLCs, robots, industrial computers and HMI panels over the Internet. Today, remote management alone is no longer enough and Ewon routers are the only ones to offer you much more. They can read (and write) data from remote PLC control systems from SIEMENS, Allen-Bradley, Mitsubishi, Omron, Schneider, Modbus, etc.  They send this data over the Internet to your computer, where you save it in a database and display it in visualizations or Power BI reports. Find out more in our video guide.

The M2Web service enables mobile access to Ewon routers from any computer, tablet or smartphone via any web browser via the Talk2M cloud. In other words, this means that you don't need to install the eCatcher.exe software on your computer or phone.
