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…

PROFIBUS PA: Overview and Description

There are two flavors of PROFIBUS: PROFIBUS Decentralized Peripherals (DP) and Process Automation (PA) PROFIBUS PA is used in process automation. The physical layer of PROFIBUS PA is Manchester Encoded Bus Powered (MBP), and the physical layer for PROFIBUS DP is RS-485. Even though a different physical layer is employed, PROFIBUS PA is the same…
