Belden Upgrades HiOS Software with Time-Sensitive Networking Support through 802.1Qbv Time-Aware Scheduler

Hirschmann’s Operating System for OCTOPUS II and RSPE 35/37, Together with Industrial HiVision, Improves Real-Time and Standardized Ethernet Data Transfer

St. Louis, Missouri - February 05, 2019 - Belden Inc., a global leader in signal transmission solutions for mission-critical applications, today released version 7.3 of its Hirschmann Operating System (HiOS). The software update enables Time-Sensitive Networking (TSN) support with a new 802.1Qbv time-aware scheduler. Now, customers can achieve predictable latency and greater reliability by allowing dedicated time slots to be available for real-time data on every device in the Ethernet network.

“Despite the data transfer benefits of the IIoT, congestion and bandwidth challenges remain big issues for system engineers,” said Mark Cooksley, product manager at Belden. “The HiOS TSN upgrade means that no data, especially mission-critical information, will be held up. Now, time-critical and non-time-critical applications can be run simultaneously on the same network.”

Key benefits from the upgraded HiOS 7.3 software include:

  • Reduced operating costs because separate networks for time-sensitive and non-time-sensitive data are not required.
  • Enhanced network efficiency since new TSN protocols can be added to the system over time.
  • Optimal network performance given both time-critical and non-time-critical devices can hook up to the same network without latency concerns.

Hirschmann’s HiOS system is well-suited for any industrial setting that uses time-sensitive data and requires immediate, reliable communication between devices, especially for machine-to-machine communication and motion control applications. The software’s comprehensive security features also make it ideal for use in high-risk industries, such as power transmission and distribution, oil and gas, general manufacturing, automotive, transportation and mass transit, rail-rolling stock and aerospace markets.

The new TSN-enabled software is available for download through the Belden website or help desk system at no cost to existing users of RSPE 35/37 or OCTOPUS switches with a field-programmable gate array (FPGA).
