Press release date: February 8, 2013

ATLANTA -- The new Scalance X-200RNA Redundant Network Access (RNA) modules from Siemens Industry, Inc. offer fault-tolerant, bumpless industrial Ethernet communications in new or existing networks.

Designed for applications demanding high network availability, the RNA modules cost effectively connect terminal devices into redundant network structures.

The Scalance X-200RNA modules comply with the IEC 63439-3 standard. Supported network architectures include star, ring or tree structures using Parallel Redundancy Protocol (PRP) or ring structures using High Availability Seamless Redundancy Protocol (HSR).

The RNA modules are available in either a plastic enclosure with four electric RJ45 ports, or a metal enclosure with two electric ports and two electric/optical combo-ports accommodating Small Form-Factor Pluggable (SFP) transceivers and a wide-range of power supplies.  Each offers an IP20 degree of protection and is designed for cubical mounting. Diagnostics are readily available via LED, integrated Web server or signaling contact.

Additionally, Siemens Softnet-IE RNA software affordably connects PCs with two physical interfaces to parallel networks without adding program overhead or additional HW.
