Glossary
Update
The process of updating firmware in a device. The option module can be updated
using various Allen-Bradley software tools. See
Zero Data
When communication is disrupted (for example, a cable is disconnected), the
option module 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 option module, it will
stay running but at zero Reference.
