Overview

---

The Ethernet standard for automation is called PROFINET.

With more than 40 million nodes deployed worldwide, PROFINET is the most widely used Industrial Ethernet standard for automation.
PROFINET's ability to speed up processes, boost output, and increase plant availability is advantageous to businesses.

Benefits

The open Industrial Ethernet standard for automation is called PROFINET.

Based on Industrial Ethernet is PROFINET.

IT standards and TCP/IP are used by PROFINET.

Ethernet over PROFINET is real-time.

Fieldbus systems may be seamlessly integrated thanks to PROFINET.

PROFINET facilitates failsafe communication through both IWLAN and PROFIsafe.

Performance

Product quality and productivity define a company's level of market success. To achieve higher production, therefore, deterministic synchronisation of devices, dynamic drives, high-speed controllers, and precise motion control are essential. They simultaneously enable maximum product quality and fast production rates.

Speed and precision

Applications involving fast motion control require deterministic and exact data interchange. Isochronous real-time (IRT) drive controllers are used to do this.

PROFINET enables predictable and fast communication with isochronous mode and IRT. This keeps the input, network, CPU processing, and output cycles of a system in sync—even when there is concurrent TCP/IP traffic. PROFINET's fast cycle durations allow for increased machine and plant efficiency while maintaining high precision and product quality.

Communication between CPUs and drives is possible regardless of vendor thanks to the standardised PROFIdrive profile.

Large quantity structures

The limitations on the range of machines and systems that can be implemented can be removed with the usage of PROFINET. Multiple controllers can communicate with their designated field devices inside a single network. Each PROFINET network can have an almost infinite number of field devices since all IP addresses are usable.

High data rate

PROFINET achieves a far higher data rate than earlier fieldbuses by using 100 Mbit/s in full duplex mode. This implies that not only the process data but also other plant data can be sent over TCP/IP without any issues. Thus, PROFINET satisfies the joint industrial requirements for large-volume data transmission for extra application sections and high-speed input/output data transmission at the same time. Because of PROFINET methods, even massive data transmissions, like those from cameras, have no negative impact on the accuracy and speed of IO data transmission.

Media redundancy

Ring topology redundancy installation can lead to improved plant availability. Integrated PROFINET interfaces can also be used to establish media redundancy in addition to external switches. 200 ms reconfiguration times can be attained by using the media redundancy protocol (MRP). Should communication be lost in a single area of the ring system, this prevents a plant halt and allows for the unhurried completion of any required maintenance or repairs.

PROFINET with IRT in ring topologies provides enhanced media redundancy for planned duplication (MRPD) in motion control applications. MRPD runs in a bumpless mode without requiring reconfiguration time. The procedure can carry on uninterrupted even in the event of a communication breakdown (such as a cable break).
