Glossary G-3
Bradley products. DriveTools SP (version 1.xx or higher) can be used
with Allen-Bradley drives. Information about DriveTools SP can be
accessed at http://www.ab.com/drives/drivetools.
E
EDS (Electronic Data Sheet) Files
EDS files are simple text files that are used by network configuration
tools such as RSNetWorx for DeviceNet to describe products so that you
can 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 be found at http://www.ab.com/networks/eds.
Explicit Messaging
Explicit Messages are used to transfer data that does not require
continuous updates. They are typically used to configure, monitor, and
diagnose devices over the network.
F
Fault Configuration
When communications are disrupted (for example, a cable is
disconnected), the 1769-SM1 and connected DPI or SCANport drive can
respond with a user-defined fault configuration. The user sets the data
that is sent to the drive using specific fault configuration parameters in
the 1769-SM1. When a fault action parameter is set to use the fault
configuration data and a fault occurs, the data from these parameters is
sent as the Logic Command, Reference, and/or Datalink(s).
Flash Update
The process of updating firmware in a device. The 1769-SM1 can be
flash updated using the X-Modem protocol and a 1203-SSS converter
(firmware 3.xx or higher), the Allen-Bradley software tool
ControlFLASH, or the built-in flash capability of DriveExplorer (version
4.01 or higher).
H
HIM (Human Interface Module)
A device that can be used to configure and control a DPI or SCANport
drive. DPI HIMs (20-HIM-xxx) can be used to configure connected DPI
peripherals.
Hold Last
When communications are disrupted (for example, a cable is
disconnected), the 1769-SM1 and connected drive(s) can respond by
holding last. Hold last results in the drive receiving the last data received
via the DeviceNet connection before the disruption. If the drive was
running and using the Reference from the 1769-SM1, it will continue to
run at the same Reference.
