EMC
The ability of a product to operate within its intended
electromagnetic environment and to accept or emit RF
disturbances within defined limits.
EtherNet/IP
The EtherNet/IP network offers a full suite of control,
configuration, and data collection services by layering
the Common Industrial Protocol over the standard
protocols used by the Internet (TCP/IP and UDP).
EtherNet/IP uses TCP/IP for general
messaging/information exchange services and UDP/IP
for I/O messaging services for control applications. This
combination of well-accepted standards provides the
functionality required to support both information data
exchange as well as control applications.
