Using Auto Warning
Since industrial Ethernet devices are often located at remote areas 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
warning 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 of devices almost instantaneously when
exceptions occur. The EDS supports different approaches such as email and relay output to warn
engineers automatically.
Configuring Email Warning
The Auto Email Warning function uses e-mail to alert the user when certain user-configured
events take place.
Three basic steps are required to set up the Auto Warning function:
1. Configuring Email Event Types
Select the desired Event types from the Console or Web Browser Event type page (a
description of each event type is given later in the Email Warning Events setting subsection).
