Type 0/Type 1/Type 2 Control
When transmitting I/O, the adapter can use different types of messages for
control. The Type 0, Type 1, and Type 2 events help Rockwell Automation
personnel identify the type of message that is used.
U
Update
The process of updating firmware in a device. The adapter can be updated
using various Allen-Bradley software tools. See
for more information.
Z
Zero Data
When communication is 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
stays running but at zero Reference.
