Monitoring EGD Devices

The EGD Management Tool monitors the devices on the Ethernet Global Data network provided it has access to
that network. To have access to the EGD network, the computer running the EGD Management Tool must have
a Network Interface Card that connects to the EGD network. Consult with your local network administrator if
you need help connecting the computer to the Ethernet Global Data network.
The screen below shows the EGD Monitoring Tool connected to and monitoring an EGD network.

Devices that have a red 'x' are not responding to communications from the EGD Management Tool. Devices
that have a yellow triangle have some kind of error or warning condition that may require attention. Use the
browser pane to select the device to get further information about the failures being reported. The EGD
Management Tool reports a configuration mismatch for PLCs that have multiple Ethernet Interfaces. Only one
of the interfaces in a PLC is queried by the EGD Management Tool, so only a subset of the exchanges in the PLC
is visible online through that interface.
Online information is only available for EGD Class 2 devices (devices that support the EGD commands). This
includes all PACSystems controllers. It does not include most of the older Series 90 PLCs.
When the EGD Management Tool is used online, it periodically sends Ethernet Global Data commands to each
device. This may have a performance impact on the network and the devices on the network. Before using the
EGD Management Tool in a production environment, be sure to assess the performance impact of its use on
your application.
