Controller Area Network.
See Low-speed CAN.
Frame used to transmit the actual data of a CAN Object. The RTR bit is
clear, and the data length indicates the number of data bytes in the frame.
In addition to fields used for error detection/correction, a CAN frame
consists of an arbitration ID, an Identifier Extension, SOF and EOF bits, the
RTR bit, a four-bit Data Length Code, and zero to eight bytes of data.
Within NI-CAN, an object that encapsulates a CAN network interface on
the host computer.
A CAN identifier, along with its associated data.
Frame used to request data for a CAN Object from a remote node; the RTR
bit is set, and the data length indicates the amount of data desired (but no
data bytes are included).
A set of objects that share a common structure and a common behavior.
An association between two or more nodes on a network that describes
when and how data is transferred.
A device that receives data from sensors and sends data to actuators in order
to hold one or more external, real-world variables at a certain level or
condition. A thermostat is a simple example of a controller.
See node.
Multi-drop digital communication network for sensors, actuators, and
controllers.
Dynamic link library.
Direct memory access.
