DeviceNet Manager Software
DeviceNet Manager software is a tool for configuring and monitoring
DeviceNet networks and connected devices. It is a 16-bit Windows
application that runs on Windows

95, Windows 98, and Windows NT
®
(4.0 or greater). Information about DeviceNet Manager software can be
accessed at http://www.ab.com.
DeviceNet Option
Devices such as drives, controllers, and computers usually require an option
to provide a communication interface between them and a network such as
DeviceNet. A DeviceNet option reads data on the network and transmits it
to the connected device. It also reads data in the device and transmits it to
the network.
Options are sometimes also called adapters, cards, gateways, modules, or
peripherals.
E Electronic Data Sheet (EDS) Files
EDS files are simple text files that are used by network configuration tools,
such as DeviceNet Manager and RSNetWorx for DeviceNet, to help you
identify products such as 1329I units and easily commission them on a
network. EDS files describe a product device type, revision, and
configurable parameters. EDS files for many Allen-Bradley products can
either be downloaded from the product or found at http://www.ab.com/
networks/eds.
Explicit Messaging
Explicit messages are used to configure, monitor, and diagnose devices.
F Fault Action
A fault action determines how the option and connected 1329I unit act when
there is a communications fault (e.g., a cable is disconnected).
Faulted Node Recovery
If you have software that supports this feature, you can change a
configuration of a device that is faulted on the network. For example, if you
add a device to a network and it does not have a unique address, it will fault.
If it has faulted node recovery, you can change its node address so that it is
no longer faulted.
H Hold Last State
When communications are disrupted (e.g., a cable is disconnected), the
DeviceNet option and 1329I unit can respond by holding last state. Hold last
state results in the 1329I unit receiving the last data received via the
DeviceNet connection before the disruption. If the 1329I unit was in RUN
mode and using the reference from DeviceNet, it will continue to run at the
same reference.
