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 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.

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

EDS = MOXA EtherDevice Switch

Chapter 2 Getting Started

This chapter explains how to access MOXA EtherDevice Switch for the first time. There are three ways to access the switch: serial console, Telnet console, and web browser. The serial console connection method, which requires using a short serial cable to connect MOXA EtherDevice Switch to a PC’s COM port, can be used if you do not know MOXA EtherDevice Switch’s IP address. The Telnet console and web browser connection methods can be used to access MOXA EtherDevice Switch over an Ethernet LAN, or over the Internet.

The following topics are covered:

! Using the RS-232 Serial Console (115200, None, 8, 1, VT100)

! Using the Telnet Console

! Using Web Configuration

EDS-508 Series User’s Manual Getting Started

Using the RS-232 Serial Console (115200, None, 8, 1, VT100)

NOTE

Connection Caution!

1. You cannot connect to EDS simultaneously through the serial console and via Telnet.

2. You can connect to EDS simultaneously by web browser and serial console, or by web browser

and via Telnet.

3. However, we recommend that when connecting to EDS by web browser, you do not

simultaneously connect by either serial console or via Telnet. By following this advice, you can maintain better control over how your MOXA EtherDevice Switch is managed.

We recommend using MOXA PComm Terminal Emulator, which can be downloaded free of charge from Moxa’s website. After installing PComm Terminal Emulator, take the following steps to access the RS-232 Console utility.

Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to connect MOXA EtherDevice Switch’s RS-232 Console port to your PC’s COM port (generally COM1 or COM2, depending on how your system is set up).

Using the 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 (by 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 subnetwork. 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.

Accessible IP

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

# Only one host of specific IP address can access the NE-4000T

Enter “IP address/255.255.255.255” (e.g., “192.168.1.1/255.255.255.255”)

# Hosts on the specific subnet can access the NE-4000T

Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”)

EDS-508 Series User’s Manual Featured Functions

Factory Default

The Factory Default function is included to give users a quick way of restoring MOXA EtherDevice Switch’s configuration settings to their factory default values. This function can be accessed from either the Console utility or Web Browser interface.

NOTE

After activating the Factory Default function, you will need to use the default network settings to re-establish a web-browser or Telnet connection with your MOXA EtherDevice Switch.

Using Port Trunking

Port Trunking allows devices to communicate by aggregating up to four links in parallel and a maximum of 4 ports for each link. This means that users could connect one EDS to another EDS by port trunking to double, triple or quadruple the bandwidth of the connection.

The Concept of Port Trunking

Moxa developed the proprietary port trunking protocol to provide the following benefits:

# Provide a flexible network connection by doubling, tripling, or quadrupling the bandwidth of

a link.

# Providing redundancy—if one link is broken, the other ports share the traffic within this link. Port trunking can aggregate up to four ports between two EDSs. If all ports on both Switch units are configured as 100BASE-TX and they are operating in full duplex, the potential bandwidth of the connection will be 800 Mbps.
