DriveTools SP Software
A software suite designed for running on various Microsoft Windows
operating systems. This software suite provides a family of tools, including
DriveExecutive software (version 3.01 or later), that you can use to
program, monitor, control, troubleshoot, and maintain Allen-Bradley
products. DriveTools SP software can be used with PowerFlex 7-Class and
PowerFlex 4-Class drives, and legacy drives that implement the SCANport
communication interface. Information about DriveTools SP software can be
accessed at

E
EDS (Electronic Data Sheet) Files
Simple text files that are used by network configuration tools such as
RSNetWorx for DeviceNet software to describe products so that you can
easily commission them on a network. EDS files describe a product device
type and revision. EDS files for many Allen-Bradley products can be found
at

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 Action
A fault action determines how the adapter and connected drive act when a
communication fault (for example, a disconnected cable) occurs or when
the controller is switched out of run mode. The former uses a
communication fault action, and the latter uses an idle fault action.
Fault Configuration
When communication is disrupted (for example, a cable is disconnected),
the adapter and PowerFlex 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 adapter. 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
Datalinks.
Faulted Node Recovery
This DeviceNet feature lets you 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 you have a configuration tool
that supports faulted node recovery and your adapter is using parameters to
set its node address and data rate, you can change the node address.
H Heartbeat Rate
The heartbeat rate is used in Change of State (COS) data exchange. It is
associated with producing data once every EPR (Expected Packet Rate)
duration. There may be four heartbeats before a time-out occurs.
