the world’s best Industrial Ethernet Switch designed for connecting Ethernet-enabled devices in industrial field applications. This manual is for the ICP DAS Managed Switch.

Overview

The Managed Industrial Ethernet Switch is designed upon concepts of reliability, quick recovery, easy configuration, self-healing and SCADA for status monitoring. Besides, all models in Managed Switch mechanism is also designed to meet IP301 above for working under harsh environment.

Unlike other existing ring switch or managed Ethernet switch on the market, the ICPDAS Managed Switch is much more easy to use and absolutely free of software setting.

Ethernet Switch

Ethernet is an ideal medium to transport large volumes of data, at speed, across great distances. Previously, multiple networks carrying specific protocols were installed side by side to carry out unique tasks. This inevitably led to project costs increasing as additional fiber optic or copper cables were installed to deal with the increasing volume of data. Using Ethernet a single fiber optic cable can carry multiple protocols. Furthermore, manufacturers are exporting their legacy protocols onto Ethernet, designing new IP based communication protocols and providing embedded Web-Pages within devices that offer real-time information using simple tools like Internet Explorer and Netscape Navigator.

Unfortunately, although network hardware has dramatically increased in speed and technology over the past decade the poor perception of Ethernet has remained; namely as being difficult to fault-find and critically being a non-deterministic network. A key development that overcame some of these issues was the advent of the Ethernet Switch.

Early Ethernet networks were based on a hub or repeater. These units have no intelligence and therefore are unable to identify any information contained within the Header frame of an Ethernet packet. This means that it is not capable of determining which port to send the frame to. Therefore, every frame is sent to every port. A network of repeaters and hubs is called a ‘Shared Ethernet’ or ‘Collision Domain’. Various devices will all compete with each other before sending data using ‘Carrier Sense Multiple Access / Collision Detect’ (CSMA/CD) protocol. This means that only one system is allowed to proceed with a transmission of a frame within a Collision Domain at any one time. This is a major disadvantage when using Hubs and Repeaters within a network.

A switch, like a hub, has to forward and receive packets from one network or device to another. The switch could forward all packets, but if this was the case it would have similar behaviour to a hub. It would be more intelligent if the switch only forwarded packets which needed to travel from one network or device to another. To do this, the switch must learn which devices or networks are connected to each port. In simplistic terms; it needs to learn the destination and source ports of each and every packet received on each individual Switch port. Once learnt, any identically addressed packet will be automatically be forwarded. With today’s enhanced processing power the introduction of a Switch has significantly increase network bandwidth.

Industrial Ethernet

Industrial rated Switches are intended to be installed in both harsh climatic environments and noisy electrical installations. Such Switches are an excellent example of true industrial design principles –

 very high operating temperatures (down to -30°C an d up to 75°C)  dual input power supplies  wide DC operating voltages

In Roadside and tunnel applications distances between cabinets with a suitable power supply can be challenging. Naturally, fiber optic cable is the preferred solution. Using single mode fiber, runs of up to 85km are possible. Even using standard CAT5e copper cable the Industrial Switch supports the long cable specification and distances of up to 185m are viable. However, the domain of Ethernet has always been controlled by the IT department who normally configured office networks with an iron fist and dictated to the organisation how the network would be designed. Complex network recovery protocols

TDRS4050601

Industrial Ethernet Layer 2 Managed Switch User Manual

like spanning tree, and SNMP to help with fault finding and system analysis were often employed to enhance network resilience. If a network failure occurred the IT department would casually look at repairing the equipment; there was no real rush as it was an office network.

However, with industrial Ethernet you need very fast repair time and with an IT department not readily available on the roadside, maintenance personnel need to be made aware of the fault, find the error and repair it - quickly. To aid this, unique network recovery features are employed to significantly enhance network recovery times. When an IT department requires a level of redundancy a common method is to employ the spanning tree protocol. However, spanning tree can be complex to program and critically can take over 30 seconds to detect and recover from the fault – far to long for critical applications!

ICP DAS Managed Switch incorporates propriety protocols that enable multiple Switches to be placed into a redundant ring. A single Switch, configured as the network focal point will monitor, detect and recover from a fiber or copper link failure within approximately 50mS – for the majority of applications a seamless process. The configuration process of the network focal point is simple as it must be remembered that as the switches are to be installed on the roadside the first to be called to rectify a fault will more than likely be Maintenance personnel.
