economy
segment
A special type of STB I/O segment created when an STB NCO 1113 economy
CANopen NIM is used in the first location. In this implementation, the NIM acts as a
simple gateway between the I/O modules in the segment and a CANopen master.
Each I/O module in an economy segment acts as a independent node on the
CANopen network. An economy segment cannot be extended to other STB I/O
segments, preferred modules or enhanced CANopen devices.
EDS electronic data sheet. The EDS is a standardized ASCII file that contains information
about a network device’s communications functionality and the contents of its object
dictionary. The EDS also defines device-specific and manufacturer-specific objects.
EIA Electronic Industries Association. An organization that establishes electrical/
electronic and data communication standards.
EMC electromagnetic compatibility. Devices that meet EMC requirements can operate
within a system’s expected electromagnetic limits without error.
EMI electromagnetic interference. EMI can cause an interruption, malfunction, or
disturbance in the performance of electronic equipment. It occurs when a source
electronically transmits a signal that interferes with other equipment.
EOS This abbreviation stands for end of segment. When more than 1 segment of I/O
modules is used in an Island, an STB XBE 1000 or an STB XBE 1100 EOS module
is installed in the last position in every segment that has an extension following it.
The EOS module extends Island bus communications to the next segment. Which
EOS module must be selected depends on the module types that shall follow.
Ethernet A LAN cabling and signaling specification used to connect devices within a defined
area, e.g., a building. Ethernet uses a bus or a star topology to connect different
nodes on a network.
Ethernet II A frame format in which the header specifies the packet type, Ethernet II is the
default frame format for NIM communications.
