Introduction; Feature Highlights - Siemens SIMATIC NET RUGGEDCOM RS940G Installation Manual

Introduction

The RUGGEDCOM RS940G is an industrially hardened, fully managed Ethernet switch
providing six or eight ports of Gigabit Ethernet. Six 10/100/1000Base-TX triple speed
copper ports are standard. An additional two gigabit fiber or copper ports can be
added. The RUGGEDCOM RS940G provides a cost effective way of connecting a
cluster of field devices to a Gigabit Ethernet backbone.
Designed to operate reliably in harsh industrial environments, the RUGGEDCOM
RS940G provides a high level of immunity to electromagnetic interference and heavy
electrical surges typical of environments found in electric utility substations, process
control or in curb side traffic control cabinets. An operating temperature range of
-40 to 85 °C (-40 to 185 °F) coupled with hazardous location certification (Class I
Division 2), optional conformal coating and a galvanized steel enclosure allows the
RUGGEDCOM RS940G to be placed in almost any location.
The embedded RUGGEDCOM RUGGEDCOM RS940G (Rugged Operating System)
provides advanced networking features such as Enhanced Rapid Spanning Tree
(eRSTP), Port Rate Limiting and a full array of intelligent functionality for high
network availability and manageability. The versatility and wide selection of fiber
optics allows the RUGGEDCOM RS940G to be used in a variety of applications. The
RUGGEDCOM RS940G provides two fiber optical Gigabit Ethernet ports for creating a
fiber optical backbone with high noise immunity and long haul connectivity.
RUGGEDCOM RUGGEDCOM RS940G offers advanced Layer 2 and Layer 3 networking
functions, and advanced cyber security features. Combined with the ruggedized
hardware design, RUGGEDCOM RS940G is designed for creating mission-critical,
real-time, control applications where high reliability and availability is of paramount
importance.
