About this Manual

The “Redundancy Configuration” user manual contains all the information

you need to select a suitable redundancy procedure and configure it.

The “Basic Configuration” user manual contains all the information you need

to start operating the device. It takes you step by step from the first startup

operation through to the basic settings for operation in your environment.

The “Installation” user manual contains a device description, safety instruc-

tions, a description of the display, and all the other information that you need

to install the device before you begin with the configuration of the device.

The “Industry Protocols” user manual describes how the device is connected

by means of a communication protocol commonly used in the industry, such

as EtherNet/IP and PROFINET.

The "Web-based Interface" reference manual contains detailed information

on using the Web interface to operate the individual functions of the device.

The "Command Line Interface" reference manual contains detailed informa-

tion on using the Command Line Interface to operate the individual functions

of the device.

The Network Management Software HiVision/Industrial HiVision provides

you with additional options for smooth configuration and monitoring:

XConfiguration of multiple devices simultaneously.

XGraphical interface with network layouts.

XAuto-topology discovery.

XEvent log.

XEvent handling.

XClient / Server structure.

XBrowser interface

XActiveX control for SCADA integration

XSNMP/OPC gateway

1.1 Overview of

Redundancy Procedure

Note: Informations concerning the switching time you can find on the

Hirschmann internet site (www.hirschmann-ac.com) at the end of the product

site.

Redundancy

procedure

Network topology Switching time

RSTP Random structure typically < 1 s (STP < 30 s), up to < 30 s - depends

heavily on the number of devices

Note: Up to 79 devices possible, depending on topology and configuration. If

the default values are being used, up to 39 devices are possible, depending on

the topology (see page 81).

HIPER-Ring Ring typically 80 ms, up to < 500 ms - practically indepen-

dently of the number of devices

MRP-Ring Ring typically 80 ms, up to < 500 ms - practically indepen-

dently of the number of devices

Note: In combination with RSTP in MRP compatibility mode, up to 39 devices

are possible, depending on the configuration. If the default values for RSTP are

being used, up to 19 devices are possible (see page 81).

Fast HIPER-

Ring (RSR20,

RSR30 and

MACH 1000)

Ring < 10 ms with 5 devices in ring.

With more than 5 devices, the switching time increases.
