Glossary
T
Transmission Control Protocol
(TCP)
EtherNet/IP network uses this protocol to transfer Explicit Messaging packets by
using IP. TCP guarantees delivery of data through the use of retries.
U
User Datagram Protocol (UDP)
EtherNet/IP network uses this protocol to transfer I/O packets by using IP. UDP
provides a simple, but fast capability to send I/O messaging packets between
devices. This protocol ensures that adapters transmit the most recent data
because it does not use acknowledgements or retries.
Update
The process of updating firmware in a device. The adapter can be updated by
using various Allen-Bradley software tools. Refer to
for more information.
