Rockwell Automation 22-COMM-L LonWorks Adapter - Manual (Page 67)

Glossary G-3
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 and Reference.
Flash Update
The process of updating firmware in the adapter. The adapter can be
flash updated using the Allen-Bradley software tool ControlFLASH, the
built-in flash capability of DriveExplorer (version 4.01 or higher), or
when the adapter is installed in a DSI External Comms Kit, the
X-Modem protocol and a 22-SCM-232 serial converter (version 3.xx or
higher firmware).
H
HIM (Human Interface Module)
A device that can be used to configure and control a PowerFlex 4-Class
drive. PowerFlex 4-Class HIMs (22-HIM-xxx) can be used to configure
connected peripherals.
Hold Last
When communications are disrupted (for example, a cable is
disconnected), the adapter and PowerFlex drive can respond by holding
last. Hold last results in the drive receiving the last data received via the
network connection before the disruption. If the drive was running and
using the Reference from the adapter, it will continue to run at the same
Reference.
I
Interoperability
The ability of systems from different manufacturers and of different
types to share information with each other without losing any of their
independent functional capabilities and without requiring complex
programming by the integrator.
I/O Data
I/O data, sometimes called “implicit messages” or “input/output,”
transmit time-critical data such as a Logic Command and Reference. The
terms “input” and “output” are defined from the scanner’s point of view.
Output is produced by the scanner and consumed by the adapter. Input is
produced by the adapter and consumed by the scanner.
