Fast Ethernet Redundant Ring Capability (< 300 ms)
For industrial automation applications, redundancy is an important
issue to help increase the reliability of your system. MOXA
EtherDeviceTM Redundant Switch EDS-508 comes equipped
with a redundant network protocol called Turbo Ring that
was developed by Moxa. Turbo Ring gives users an easy way
to establish a redundant Ethernet network, and with its ultra
high-speed recovery time, once any segment of your network
is disconnected, your automation system will be back to normal
in less than 300 ms.

Couple several Turbo Rings for distributed applications
For some systems, it may not be convenient to connect all
devices in the system to create one BIG redundant ring, since
some devices could be located at a remote site. Turbo Ring’s
“Ring Coupling” function helps you separate those distributed
devices into different smaller redundant rings, but in such a
way that they can still communicate with each other.
IGMP Snooping for filtering multicast traffic
Ethernet). These industrial Ethernet protocols use publisher/
subscriber communications models to multicast packets that
could flood a network with heavy traffic. IGMP Snooping provides
the ability to prune multicast traffic so that it travels only to those
end destinations that require this kind of traffic, and consequently
reduces the amount of traffic on the Ethernet LAN.
VLAN eases network planning
A VLAN is a group of devices that can be located anywhere
on a network, but which communicate as if they are on the
same physical segment. VLANs can be used to segment your
network without being restricted by physical connections—a
limitation imposed by traditional network design. Besides, since
all automation systems incorporate sensitive devices that must
be protected from unauthorized access, it is very important
to have some type of authentication system set up that only
allows authorized users to access the system. If devices belong
to different VLANs, they cannot communicate with each other,
providing extra security and protection from unwanted invasion
or traffic. The IEEE 802.1Q standard and GVRP protocol can
exchange the same interoperable parameters to keep consistent
VLAN settings over the entire network.

IGMP (Internet Group Management Protocol) is important in
industrial networking, and may be used over Ethernet with
some field bus protocols, such as Allen-Bradley EtherNet/IP,
Siemens Profibus, and Foundation Fieldbus HSE (High Speed

QoS increases determinism
EDS-508 Series Managed Redundant Switch
Quality of Service (QoS) provides a traffic prioritization capability
to ensure that important data is delievered consistently and
predictably. EDS-508 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-508 Series’
QoS capability improves your industrial network’s performance
and determinism for mission critical applications.
Port Trunking for flexible network connections
Port Trunking allows devices to communicate by aggregating
up to four links in parallel with a maximum of 4 ports for each
link. That means users could connect one EDS to another EDS
by port trunking to double, triple, or quadruple the bandwidth
of the connection.

Bandwidth management prevents unpredictable network status
Any single device on a network should not have unlimited
bandwidth, particularly when it malfunctions. The most wellknown problem is the broadcast storms caused by setting up
the wrong topology, or by devices that malfunction. The EDS508 Series not only prevents broadcast storms, but also can
configure the ingress/egress rate of unicast/multicast/broadcast
packets, and in this way give administrators full control of limited
bandwidth to prevent unpredictable faults.
Port Lock to allow authorized access by specific MAC addresses
The EDS-508 series can assign protected static MAC addresses
to specific ports. By using the Port Lock function, locked ports
will not be able to learn other addresses but only allow the traffic
that comes from the preset static MAC address, helping to block
unwanted invasion and usage.

Port Mirroring for online monitoring
In some cases, a network is so large that it is difficult to achieve
the expected level of communications. Industrial communications
applications use more of a command-response style than the filetransfer 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-508
Series’ mirroring port function helps to ensure that the system
behaves as expected.
Automatic warning by event
of devices almost instantaneously when exceptions occur.
The traditional way of determining device status is to poll devices
periodically, but this is not “real-time” enough, and is not very
efficient. Warning messages must be actively triggered by events.
To take care of these requirements, industrial Ethernet Switches
need features such as:
Warning by e-mail
The EDS-508 Series can send out a warning e-mail when an
exception is detected, providing system managers with real-time
alarm messages.

Cold Start
Warm Start
Link On

Topology Change

Traffic Overload
Warning by relay output
The EDS-508 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
EDS-508 Series Managed Redundant Switch
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
switches that connect these devices must take responsibility for
providing system maintainers with real-time alarm messages.
Even when control engineers are out of the control room for an
extended period of time, they can still be informed of the status
With two digital inputs, the EDS-508 Series can integrate sensors into
its automatic alarm mechanism, turning warning messages into IP
network by e-mail, SNMP trap, or OPC.
Replace Faulty Devices
To reduce the effort required to repeatedly configure IP
addresses, the EDS-508 Series comes equipped with DHCP/
BootP server and RARP protocol to automatically set up IP
addresses of Ethernet-enabled devices.

Easy Browser-based Configuration
The EDS-508 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-508
units simultaneously.

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