See instance.
A software design methodology in which classes, instances, attributes, and
methods are used to hide all of the details of a software entity that do not
contribute to its essential characteristics.
Network connection in which data is transmitted from the source to its
destination(s) without need for an explicit request. Although data transfer
is generally unidirectional, the protocol often uses low level
acknowledgments and error detection to ensure successful delivery.
Connections that transfer data on the network at a specific rate.
Request/response connection in which a request for data is sent to a device,
and the device sends back a response with the desired value.
A formal set of conventions or rules for the exchange of information among
nodes of a given network.
Random-access memory.
Within NI-CAN, anything that exists in another node of the device network
(not on the same host as the NI-CAN driver).
This bit follows the arbitration ID in a frame, and indicates whether the
frame is the actual data of the CAN Object (CAN data frame), or whether
the frame is a request for the data (CAN remote frame).
Network connection in which a request is transmitted to one or more
destination nodes, and those nodes send a response back to the requesting
node. In industrial applications, the responding (slave) device is usually a
sensor or actuator, and the requesting (master) device is usually a controller.
Also known as master/slave.
