High transmission rate
With PROFINET, it is possible to transfer standard IT communication with high data rates and reaction-free to the cyclic IO communication.
By using Ethernet in full duplex mode, PROFINET achieves a significantly higher transmission rate than previous fieldbuses. Thanks to this, both the process data and other plant data can be transferred via TCP/IP without any problems. PROFINET easily comes up to industrial requirements such as simultaneous transmission of fast IO data and large volumes of data for other parts of the application. Due to PROFINET mechanisms, even the transfer of large volumes of data that are common for video-data does not compromise speed and precision of IO data transfer.
By using Ethernet in full duplex mode, PROFINET achieves a significantly higher transmission rate compared to conventional fieldbus technology.
100 Mbit/s give PROFINET the capability of transferring large quantities of data via TCP/IP at the field level in addition to IO communication.
In higher-level plant networks, Ethernet based on 1 Gbit/s can be used for the data-intensive backbone communication without any problems.
The data rate of PROFINET with full duplex capability is approximately 18 times higher than with PROFIBUS.
Data-intensive applications on the backbone can quickly and efficiently exchange plant and production data.
