PROFINET to demonstrate high speed at Hanover Fair

Germany

At this year's Hanover Fair, a technology model on the PI (PROFIBUS & PROFINET International) booth (Hall 9, Booth D05) will demonstrate the available performance upgrade for PROFINET with extremely short cycle times of 31.25 µs. This exceptionally high performance is made possible by the implementation of the current PROFINET Specification V2.3, in which the ‘Dynamic Frame Packing,’ ‚Fast Forwarding,’ and ‘Fragmentation’ mechanisms are defined. The innovative procedure has been used to achieve extremely short cycle times and an extremely efficient bandwidth utilization by PROFINET devices.

The technology demonstration will effectively show not only the cycle time of 31.25 µs but also the harmonious parallel transmission of TCP/IP data on the PROFINET bus. A measuring technology application underscores the many possible uses of PROFINET for all application scenarios in the automation industry.

The core of the technology model is the new ERTEC 200P from Siemens, which is the most powerful ASIC in its class. Devices built with the ERTEC 200P can transmit IO data at cycle times as short as 31,25 µs. New devices that are being developed in accordance with PROFINET Specification V2.3 remain fully compatible with devices in current use.

The new ASIC is suitable for widespread use, such as for measuring technology devices, converter controls, hydraulic control loops, high-precision I/O devices, motion control drives, and fast encoders.
