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 end of segment. When more than one segment of I/O modules is used in an island,
an STB XBE 1000 EOS module is installed in the last position in every segment
except the final segment on the island. Its job is to extend island bus
communications and send 24 VDC for logic power to the next segment.
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.0
Ethernet II A frame format in which the header specifies the packet type, Ethernet II is the
default frame format for STB NIP 2212 communications.
fallback state A safe state to which an Advantys STB I/O module can return in the event that its
communication connection fails.
fallback value The value that a device assumes during fallback. Typically, the fallback value is
either configurable or the last stored value for the device.
FED_P Fipio extended device profile. On a Fipio network, the standard device profile type
for agents whose data length is more than eight words and equal to or less than
