CAN
Korrekturausdruck
CAN stands for Controller Area Network and was originally
developed by Bosch and Intel as a bus system for vehicles. In the
meantime, CAN has also proven suitable as a field bus in automation technology. Like practially all field buses, CAN is based on the
OSI 7 layer model. CAN is normed in ISO 11898 only for OSI layers
1 and 2 and is based on a bus structure. The transmission speed
can be selected in a range of 20 kBit/s to 1 Mbit/s. The application
layer is defined by the layer-7 protocols based on CAN, e.g.
DeviceNet over CANopen. Due to the access method CSMA/CA
and object-oriented addressing, CAN is particularly suitable for setting up very efficient event-controlled systems. In the multimaster
system CAN, data can be exchanged directly between any number
of clients.
CE

the applicable European directives.
Client

out.
CLSID (with OPC)
The class ID is a worldwide unambiguous code for a certain COM
object. Via the CLSID, a client can address a certain COM object. A
CLSID consists of 128 bit. To receive an unambiguous CLSID, the
time of generation and hardware information of the computer used
for generation are included in the CLSID.
CNC
An abbreviation for computerized numerical control. CNCs are
used primarily in machine tools.
