Terms & Phrases
Block Size (BS) The BS (Block Size) defines the maximum number of frames which can be send before another
flow control frame has to be sent.
Buffer Used as synonym for the data of the circular buffer on the Hardware. See also Buffer Handling .
Configurations All the setups that are done to change or modify a session not the database. Though there is an
access to maintain the databases via the menu item Configurations.
CPID Control Packet Identifier. 1 Byte value identifies a packet of data bytes to control and manipulate
ECUs (Devices) externally.
Database The term database is here used to determine the data that describe vehicles by the build in
ECUs, the frames of each ECU and the signals of each frame.
Parts of a Database are:
16
- included vehicles,
- included ECUs,
- included Frames and Diagnostic data,
- included Signals.
Each vehicle contains ECUs; the ECUs contain Frames and Diagnostic data. Frames and
Diagnostic data each contain Signals.
DID Data Identifier. 1 Byte value identifies static information stored in the ECUs.
DPID Data Packet Identifier. 1 Byte value identifies a packet of diagnostic data bytes containing nonstatic
information.
DTC Diagnostic Trouble Code.
ECU Electronic Control Unit. Here in the meaning of electronic boxes that are build in vehicles and that
communicate via the CAN bus.
Filter CAT provides Pass Through Filter only. The data are already filtered by the Hardware.
Frame The frames are the messages that are transported via the CAN bus.
FSA Functional System Address. Identifies a group of ECUs that build up a functional system.
Layout The layout means the desktop and desktop configuration of CAT application.
Padding Padding means to fill up the Data Byte Field of CAN Frames with 0's, so that the frames always
contain 8 Data Bytes.
Separation Time The ST (Separation Time) defines the minimum amount of time in ms, which must be between
consecutive frame transmissions of a multi frame message.
Session The term session is here used to describe the settings done to work with CAT
Parts of a Session are:
- the link to a database,
- the frames that shall be displayed in the frame list window,
- the signals that shall be displayed in the signal list window,
- the configured frames that shall be transmitted inclusive the conditions,
- the filter conditions,
- the CAN setups (selected or configured physical layer / Baud Rate),
- the buffer division sizes,
- the buffer content (when uploaded)
- the layout settings for the graphical user interface, column / fonts sizes and windows
arrangements.
Signal The signals are the interpreted data of the CAN frame. See also chapter Signal Types.
Trigger Trigger used as short form for trigger event. There is a trigger event when the trigger conditions
are fulfilled. Trigger events are not necessarily frames that appear on the bus. See also chapter Configurations |
Trigger.
