incorporated within each component of the electrical power system for power automation applications.

IEEE 1588, which was published in November 2002, expands the performance capabilities of Ethernet networks
to control systems that operate over a communication network. In recent years an increasing number of
electrical power systems have been using a more distributed architecture with network technologies that have
less stringent timing specifications. IEEE 1588 generates a master-slave relationship between the clocks, and
enforces the specific timing requirements in such power systems. All devices u ltimately get their time from a
clock known as the grandmaster clock. In its basic form, the protocol is intended to be administration free.”

How Does an Ethernet Switch Affect 1588 Synchronization?

The following content is taken from the NIST website at http://ieee1588.nist.gov/switch.htm:
“An Ethernet switch potentially introduces multi -microsecond fluctuations in the latency b etween the 1588

grandmaster clock and a 1588 slave clock. Uncorrected these fluctuations will cause synchronization errors.
The magnitude of these fluctuations depends on the design of the Ethernet sw itch and the details of the
communication traffic. Exp eriments with prototype i mplementations of IEEE 1588 indicate that with suitable
care the effect of these fluctuations can be successfully managed. For example, use of appropriate statistics in
the 1588 devices to recognize significant fluctuations and use suitable averaging techniques in the algorithms
controlling the correction of the local 1588 clock will be good design means to achieve the highest time
accuracy.”

Can Ethernet switches be designed to avoid the effects of these
fluctuations?

A switch can be designed to support IEEE 1588 while avoiding the effects of queuing. I n this case two
modifications to the usual de sign o f an Ethernet switch are necessary:

1. The Boundary Clock and Transparent Clock functionalities defined by IEEE 1588 must be implemented
in the switch.

2. The switch must be configured so that it does not pass IEEE 1588 message traffic using the normal
communication mechanisms of the switch.

Such an Ethernet switch will synchronize clocks directly connected to one of its ports to the highest possible
accuracy.

Warning Notification

Since industrial Ethernet devices are often located at the endpoints of a system, these devices will not always
know what is happening elsewhere on the network. This means that an industrial Ethernet switch that connects
to these devices must provide 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 b e informed of the status of
devices almost instantaneously when exceptions occur. The Moxa switch supports different approaches to warn
engineers automatically, such as email, trap, syslog and relay output. It also supports two digital inputs to
integrate sensors into your system to automate alarms by email and relay output.

System Event Settings

System Events are related to the overall function of the switch. Each event can be activated independently with
different warning approaches. The Ad ministrator can decide the severity of each system event.
