Term/Acronym
The ability of a product to operate within its intended
electromagnetic environment and to accept or emit RF
disturbances within defined limits.
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.
The Media Access Controller Identifier (MAC ID) is an
identification value assigned to each node on the
DeviceNet Network. This value distinguishes a node with
all other nodes on the same link.
A connection to a link that requires a unique MAC ID.
The physical connection between the power supply and
the trunk line.
The resistor (121 ohm, 1% Metal Film, 0.25 W or larger)
connected at both the ends of a trunk line.
The cable path between terminators that represents the
network backbone. It can be made of thick, thin, or flat
cable and connects to taps or directly to the device.
