EtherDevice™ Switch EDS-726 Series

Gigabit Ethernet Redundant Ring Capability (< 300 ms)
Ethernet has become the default data communications medium for industrial automation applications. In fact, it's not uncommon for video, voice, and high-rate industrial application data transfers to be integrated into one network. MOXA EDS-726, which comes equipped with a redundant Gigabit Ethernet protocol called Gigabit Turbo Ring, gives system maintainers a convenient means of setting up a versatile yet stable Gigabit Ethernet network. With Gigabit Turbo Ring, if any segment of the network is disconnected, your automation system will be back to normal in under 300 ms.




LACP for flexible network connections
IEEE 802.3ad (LACP, Link Aggregation Control Protocol), provides flexible network connections and a redundant path for critical devices. EDS-726 allows devices to communicate by aggregating up to four links in parallel, with a maximum of eight ports for each link for optimum and flexible network connection. If one of the eight ports fails, the other seven ports will back up and share the traffic automatically. LACP will exchange information to determine whether the ports selected in a group can be trunked together.




IEEE 802.1X enhances user authentication
EDS-726 supports IEEE 802.1X (Port-Based Network Access Control) to enhance user authentication. Only authorized users can access the port. Authentication is done using the local user database or an external RADIUS server.




IGMP Snooping and GMRP for filtering multicast traffic
EDS-726 supports IEEE 802.1D-1998 GMRP (GARP Multicast Registration Protocol) and IGMP Snooping provides the ability to prune multicast traffic so that it travels only to those end destinations that require this kind of traffic, reducing the amount of traffic on the Ethernet LAN.

VLAN eases network planning
VLANs can be used to segment your network without being restricted by physical connections, a limitation imposed by traditional network design. If devices belong to different VLANs, they cannot communicate with each other, providing extra security and protection from unwanted invasion or traffic. EDS-726 supports IEEE 802.1Q standard and GVRP protocol that can exchange the same interoperable parameters to keep consistent VLAN settings over the entire network.

QoS increases determinism
Quality of Service (QoS) provides a traffic prioritization capability to ensure that important data is delivered consistently and predictably. EDS-726 Series can inspect IEEE 802.1p/1Q layer 2 CoS tags, and even layer 3 TOS information, to provide a consistent classification of the entire network. EDS-726 Series' QoS capability improves your industrial network's performance and determinism for mission critical applications.

RMON for efficient network monitoring and proactive capability (Available Soon)
RMON, Remote Network Monitoring, is an Internet Engineering Task Force (IETF) standard monitoring specification that allows various network agents and console systems to exchange network monitoring data. RMON provides you with comprehensive network-fault diagnosis, planning, and performance-tuning information. It helps you manage your network in a more proactive manner. If configured correctly, RMON probes deliver information before problems occur. This means that you can take action before the problems affect users.

Bandwidth management prevents unpredictable network status
The EDS-726 Series not only prevents broadcast storms, but also configures the ingress/egress rate of unicast/multicast/broadcast packets, and in this way gives administrators full control of limited bandwidth to prevent unpredictable faults.

Port Mirroring for online monitoring
In some cases, a network is so large that it is difficult to achieve the expected communications level. Industrial communications applications use more of a command-response style than the file-transfer style used in office network environments. This means that when first setting up an industrial Ethernet network, control engineers may need to use a second port to monitor the actual activity between their devices and computer host. EDS-726 Series' mirroring port function helps to ensure that the system behaves as expected.

Automatic warning by event

• Warning by e-mail
  The EDS-726 Series can send out a warning e-mail when an exception is detected, providing system managers with real-time alarm messages.
  
• Warning by relay output
  The EDS-726 Series provides two relay outputs that can be set up to indicate events with different importance to notify or warn engineers in the field, so the engineer can use the appropriate emergency maintenance procedures to respond quickly to higher priority messages.
  
• DI to integrate other important sensors
  With two digital inputs, the EDS-726 Series can integrate sensors into its automatic alarm mechanism, sending warning messages to an IP network by e-mail, SNMP trap, or OPC.

Easy Browser-based Configuration
The EDS-726 Series is easily configured over the network by web browser, Telnet console, or a Moxa provided Windows utility. In addition, Moxa's Batch Configurator can also be used to store and copy configuration parameters to multiple EDS-726 units simultaneously.

Network Management with EDS-SNMP OPC Server Pro
The SNMP OPC Server Pro software package can convert SNMP into OPC format. The vertical integration of SNMP-Management Information into existing OPC-based SCADA-packages gives the customer the ability to establish an Ethernet Network Management Application that is integrated with existing Visualization and Control applications.
