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
.
F
Flash Update
The process of updating firmware in a device. The WIM can be flash
updated using the Allen-Bradley software tool ControlFLASH in
combination with an Allen-Bradley drive-configuration software tool,
such as Pocket DriveExplorer for Pocket PC, DriveExplorer or
DriveExecutive.
H
HIM (Human Interface Module)
A device that can be used to configure and control a SCANport or DPI
drive. PowerFlex 7-Class HIMs (20-HIM-xxx) can also be used to
configure connected peripherals such as the WIM.
Hold Last
When communications are disrupted (for example, a cable is
disconnected), the WIM and PowerFlex drive can respond by holding
last. Hold last results in the drive receiving the last data received via the
DF1 connection before the disruption. If the drive was running and using
the Reference from the module, it will continue to run at the same
Reference.
N
NVS (Non-Volatile Storage)
NVS is the permanent memory of a device. Devices such as the WIM
and drive store parameters and other information in NVS so that they are
not lost when the device loses power. NVS is sometimes called
“EEPROM.”
P
PCCC (Programmable Controller Communications Commands)
PCCC is the protocol used by some controllers to communicate with
devices on a network. Some software products (for example,
DriveExplorer and DriveExecutive) also use PCCC to communicate.
Ping
A ping is a message that is sent by a SCANport or DPI product to its
peripheral devices. They use the ping to gather data about the product,
