New technology from Hirschmann

Precision time Protocol version 2 (PTP v2) precision in the nanosecond range


The Hirschmann automation and control GmbH, Neckartenzlingen, extended its product program by a new media module for the Switches of the MICE family. The new media module leads the MICE family one step further to the future.

With PTP v2 synchronization accuracies in the nanosecond range are reached, what makes a still higher accuracy possible in the entire data network. Beside so far the mechanisms, Boundary clock and Ordinary clock, used in PTP v1, was added with PTP v2 transparency clock. It is particularly meant for large net expansions and minimizes the synchronization deviations around a multiple.

The PTP modules, which are appropriate for an operating temperature from 0 to +60 degrees Celsius, are Plug and Play able and also support the Hot Swap function. The current status of the network connections is indicated over LEDs at the front.

For older devices of the MS20/30-Serie a free software update under „www.hirschmann-ac.com” can be downloaded.

The MICE Switches, which are conceived for the assembly on DIN rails, supports both Fast- and Gigabit Ethernet and also different Routing-, Redundancy- and Security Features. Thus they are suitable for the employment in industrial networks with complex applications as for instance a combined transmission of video, audio and data information in particular.
