Hirschmann RS20 Series Technical Notes

The Hirschmann RS20 series is a line of compact, DIN-rail-mounted managed industrial Ethernet switches developed by Hirschmann Automation and Control GmbH (now part of Belden Inc.). Deployed across chemical processing plants, nuclear power facilities, oil refineries, and heavy manufacturing environments, the RS20 occupies a critical position in plant-floor network infrastructure globally. Its ruggedized design — rated for operation from -40°C to +70°C — and compliance with IEC 61850, IEEE 802.1Q, and PROFINET standards have made it a default specification in brownfield automation projects across Europe, Asia-Pacific, and the Americas. The series supports redundancy protocols including RSTP, MRP (Media Redundancy Protocol), and HiPER-Ring, which are mandatory requirements in process-critical topologies where network recovery time must remain under 500 ms.

The Evolution of RS20 Architecture

The RS20 was introduced as a successor to Hirschmann's earlier MICE and SPIDER switch families, targeting applications that required managed Layer 2 switching in a compact form factor. Early RS20 variants shipped with 100BASE-TX copper ports and 100BASE-FX fiber uplinks, with management via CLI and a basic web interface. Subsequent firmware generations added SNMP v3, RMON, and IEEE 802.1X port-based authentication, aligning the platform with enterprise-grade network security requirements increasingly demanded by ICS/SCADA operators.
