Providing extensive redundancy and security functions for high network availability and data security, Belden has released the HiOS operating system release 3.0. Ensuring efficient production processes, HiOS 3.0 extends the scope of applications for switches, particularly in the energy, automotive and transportation industries.

HiOS 3.0 is available for Rail Switch Power (RSP), Rail Switch Power Lite (RSPL), Rail Switch Power Smart (RSPS) and Embedded Ethernet Switch (EES) families of switches plus modular MICE Switch Power (MSP) systems.

New functions added to the operating system include support for the Multiple MAC Registration Protocol (MMRP), which runs on top of the Security Layer and registers group MAC addresses (e.g. for Multicast) on multiple switches. In the energy sector, an IEC 61850 server can be used to transfer diagnostic information directly, for example to control systems. This means that applications such as protection devices can utilize Hirschmann switches as integral components.

"Because HiOS 3.0 provides by far the largest range of standard functions in automation, this operating system turns Hirschmann switches into the most powerful Industrial Ethernet devices on the market", commented Jürgen Schmid, Product Manager, Belden.

The redundancy methods include PRP (parallel redundancy protocol) and HSR (high available seamless ring). Their “switching times” of 0 ms ensure absolutely uninterrupted data communication. This operating system also supports link aggregation and allows combinations of multiple rings, ensuring fast network redundancy that meets the required standards. The supported security mechanisms include authentication, RADIUS, role-based access, port security, Secure Shell (SSHv2), Hyper Text Transfer Protocol Secure (HTTPS), Simple File Transfer Protocol (SFTP) and Access Control List (ACL).
