EDS-408A/405A Series User’s Manual Introduction

Inside the Future of Industrial Ethernet Technology

The trend in industrial communications and automation applications

As the world’s network and information technology becomes more mature, the trend is to use Ethernet as the major communications interface in many industrial communications, and automation applications. In fact, a whole new industry has sprung up to provide Ethernet products that comply with the requirements of demanding industrial applications.

Industrial vs. Commercial

Users have found that when moving Ethernet equipment from the comfortable office environment to the harsh and less predictable industrial environment, the commercial Ethernet equipment available in today’s market simply cannot meet the high reliability requirements demanded by industrial applications. This means that a more robust type of network equipment, commonly

referred to as industrial Ethernet equipment, is required for these applications.

Informative vs. Passive

Since industrial Ethernet devices are often located at the endpoints of a system, such devices cannot always know what’s happening elsewhere on the network. This means that industrial Ethernet communication equipment that connects these devices must take responsibility for providing system maintainers with real-time alarm messages.

MOXA EtherDevice™ Switch

MOXA EtherDevice Switch comes with a suite of useful maintenance and monitoring functions, and is designed to provide smooth and reliable operation in harsh industrial environments. You will find that MOXA EtherDevice Switch establishes a new industrial Ethernet benchmark. It is excellent for keeping automation systems running continuously, is ideal for sending status reports to help prevent system damages and losses, is a great tool for mastering your industrial Ethernet networks, and is well-suited for use with industrial device control networks.

ATTENTION

Throughout this User’s Manual, we use EDS as an abbreviation for MOXA EtherDevice Switch:

Configuration using Telnet Console

You may use Telnet to access MOXA EtherDevice Switch’s console utility over a network. To be able to access EDS’s functions over the network (using Telnet or Web Browser) from a PC host that is connected to the same LAN as EDS, you need to make sure that the PC host and EDS are on the same logical sub network. To do this, check your PC host’s IP address and netmask. By default, EDS’s IP address is 192.168.127.253 and EDS’s netmask is 255.255.0.0 (for a Class B network). If you do not change these values, and your PC host’s netmask is 255.255.0.0, then its IP address must have the form 192.168.xxx.xxx. On the other hand, if your PC host’s netmask is

255.255.255.0, then its IP address must have the form 192.168.127.xxx.

NOTE

To use EDS’s management and monitoring functions from a PC host connected to the same LAN as EDS, you must make sure that the PC host and EDS are on the same logical sub network.

Before accessing the console utility via Telnet, first connect one of MOXA EtherDevice Switch’s RJ45 Ethernet ports to your Ethernet LAN, or directly to your PC’s Ethernet NIC. You can establish a connection with either a straight-through or cross-over Ethernet cable. If you have difficulty connecting, refer to the Auto MDI/MDI-X Connection section from the Hardware installation Guide for more information about the different types of Ethernet cables and ports.

MOXA EtherDevice Switch’s default IP is 192.168.127.253.

Accessible IP

Moxa EtherDevice Switches use an IP address-based filtering method to control access to EDS.

Accessible IP Settings allows you to add or remove Legal remote host IP addresses to prevent

unauthorized access. Access to EtherDevice Switch is controlled by IP addresses. That is, if a host’s IP address is in the accessible IP table, then the host will be allowed access to the EtherDevice Switch. You can allow one of the following cases by setting this parameter

y Only one host with the specified IP address can access the EDS-408A/405A

E.g., enter “192.168.1.1/255.255.255.255” to allow access to just the IP address 192.168.1.1.

y Any host on a specific sub network can access the EDS-408A/405A

E.g., enter “192.168.1.0/255.255.255.0” to allow access to all IPs on the sub network defined by this IP address/netmask combination.

y Any host can access the EDS-408A/405A

Turbo Ring DIP Switch

EDS-408A/405A series are plug-and-play managed redundant Ethernet switches. The proprietary Turbo Ring protocol was developed by MOXA to provide better network reliability and faster recovery time. MOXA Turbo Ring’s recovery time is less than 300 ms—compared to a 3- to 5-minute recovery time for commercial switches—decreasing the possible loss caused by network failure.

A set of DIP Switches located on EDS-408A/405A’s outer casing can be easily used to configure the Turbo Ring settings in only a few seconds. Some users may wish to disable the Turbo Ring DIP Switches to avoid accidental changes to the configuration. To disable the DIP Switches, start
