But Wait –There’s More (than just APL)

Ethernet-APL is a hot topic as of late. The spec was published in 2021. First products will be entering the market over the coming year. The proposition is pretty slick: a robust, two-wire, powered Ethernet physical layer including intrinsic safety for operation in hazardous areas. Ethernet-APL is undoubtedly an enabler of digitalization in the process…

Can PROFINET Projects Employ Cat 5, 5e, Cat 6, 6a, or Cat 7 cables?

Cables in PROFINET Installations A PROFINET network is based on standard IEEE 802.3 Ethernet. You can utilize standard Ethernet cables (fiber optics or copper cables) in a PROFINET network. The most commonly used PROFINET copper cable is the 4-wire shielded, green-colored cable, which supports 100 Mbps Fast Ethernet at a distance of 100 meters. You…

PROFINET Switch vs Ethernet Switch

PROFINET does not require specialized switches. PROFINET projects can employ standard Ethernet switches that satisfy the minimum requirements of 100 Mbit/s IEEE 802.3 and full-duplex transmission.  Nowadays, most off-the-shelf Ethernet switches fulfill both requirements and therefore are suitable for PROFINET. Three terms you might encounter when choosing a switch for a PROFINET project are managed…

PROFINET Cable vs Ethernet Cable

Manufacturing environments, where PROFINET is most commonly used, are characterized by having challenging environmental conditions. In that environment, standard Ethernet cables, like those you find in your office or home, might break or damage easily. Extreme temperatures, moisture, vibrations, electro magnetic interference, and many other factors contribute to the deterioration of cables. Due to the…

PROFINET Controller vs Device

PROFINET is a communication protocol to exchange data between controllers and devices. PROFINET components employ the consumer provider model for data exchange. With this model, controllers and IO devices can both assume consumer and provider roles, leveraging the full-duplex nature of Ethernet. Now, let’s explore three component roles you can observe in a PROFINET installation:…

Is PROFINET deterministic?

PROFINET network installations typically operate in demanding industrial environments. PROFINET exchanges IO data with the appropriate speed and determinism required by manufacturing plants. To ensure suitable performance, PROFINET delivers data through the following communication channels: TCP/IP or UDP/IP for non-time-critical tasks, PROFINET Real-Time (RT) for time-critical cyclic data exchange PROFINET Isochronous Real-Time (IRT) for time-critical…

Helpful Troubleshooting Tips for PROFIBUS Projects (plus common mistakes)

This article lists the top five mistakes made in PROFIBUS networks and gives you troubleshooting information and tips on how to prevent them. Wrong cable Do not utilize telephone or other consumer-market off-the-shelf cables in a PROFIBUS network. Such cables are not built to survive in industrial facilities where PROFIBUS is used. PROFIBUS installations should…
