Hirschmann operating software (HiOS) includes TSN support with 802.1Qbv time aware scheduler

The data transfer benefits of the industrial Internet of Things (IIoT) also come with major concerns of network traffic congestion for today’s system engineers.

Hirschmann’s HiOS operating system delivers powerful, real-time and standardized Ethernet communication, equipping teams to keep up with increasing data demands, and offers intelligent and unique combinations of network redundancy protocols to meet every physical and application requirement.

With Time Sensitive Networking (TSN) support for OCTOPUS II and RSPE 35/37 via an 802.1Qbv time aware scheduler, the software offers predictable latency and greater reliability by allowing dedicated time slots to be available for real-time data on every device in the Ethernet network. Industrial HiVision enables graphical configuration and supervision of TSN parameters.

  • Easy Access Control Lists bring this important security feature to all products running HiOS.
  • For modular devices, unused slots can now be disabled.
  • Syslog over TLS ensures that confidential information is encrypted for transmission.


  • Redundant Ring Coupling ensures backwards compatibility with Classic software.
  • FuseNet protocols enable the creation of flexible redundant topologies.


  • TSN protocols can be implemented iteratively, increasing efficiency and performance of the network.
  • TSN support option allows time-critical and non-time-critical applications to run alongside each other, offering predictable latency and lower lifecycle costs with a singular Network.
