Glossary

D

DeviceNet	DeviceNet is a low-level, connection-based network that is based on CAN, a serial
protocol	bus system without a defined application layer. DeviceNet, therefore, defines a layer
	for the industrial application of CAN.
DHCP	dynamic host configuration protocol. A TCP/IP protocol that allows a server to
	assign an IP address based on a role name (host name) to a network node.

differential input A type of input design where two wires (+ and -) are run from each signal source to the data acquisition interface. The voltage between the input and the interface ground are measured by two high-impedance amplifiers, and the outputs from the two amplifiers are subtracted by a third amplifier to yield the difference between the

+and - inputs. Voltage common to both wires is thereby removed. Differential design solves the problem of ground differences found in single-ended connections, and it also reduces the cross-channel noise problem.

digital I/O	An input or output that has an individual circuit connection at the module
	corresponding directly to a data table bit or word that stores the value of the signal
	at that I/O circuit. It allows the control logic to have discrete access to the I/O values.
DIN	Deutsche industrial norms. A German agency that sets engineering and
	dimensional standards and now has worldwide recognition.

E

economy	A special type of STB I/O segment created when an STB NCO 1113 economy
segment	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 standard 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.
