HiOS provides extensive redundancy mechanisms to your state-of-the-art hard

ware. It adds Parallel Redundancy Protocol (PRP) over Gigabit, Rapid Spanning Tree 

Protocol (RSTP) over High Availability Seamless Redundancy (HSR), RSTP Ring-Only 

Mode and FuseNet network coupling protocols for maximum network uptime.

The latest Transport Layer Security (TLS) libraries enhance the security of network 

communication. The ability to disable unused slots on modular devices hinders 

unauthorized network access. Out-Of-Band management via a dedicated RJ45 port 

on the new GREYHOUND 1040 means that the devices can be managed even during 

high Central Processing Unit (CPU) load, for example if a network loop occurs.

HiOS also extends the range of applications for the latest generation of Industrial 

Ethernet products from Hirschmann. From cabling through switches and routers, 

supplemented by WLAN, firewalls and network management software, a seamless 

high availability solution for state-of-the-art automation networks is now available 

from a single supplier.

HiOS is focussed on redundancy technologies for maximum network availability. 

Devices running L2A software onwards offer unrestrained network topology design 

based on a combination of standards-based redundancy protocols and FuseNet 

coupling protocols.
