Glossary
Update The process of updating firmware in a device. The adapter can be updated using
various Allen-Bradley software tools. See
Updating the Adapter Firmware on
page 29 for more information.
Zero Data When communications are disrupted (for example, a cable is disconnected), the
adapter and drive can respond with zero data. Zero data results in the drive
receiving zero as values for Logic Command, Reference, and Datalink data. If the
drive was running and using the Reference from the adapter, it will stay running
but at zero Reference.
