Application Structure
CAT can recognize four different modes. Depending on the mode the user can analyze the traffic on the bus using
different (Views) windows:
- ONLINE Mode
Frame List View
Signal List View
Status Bar
Additional to the View windows to monitor the CAN bus, there are Online Control windows to allow the
user to send frames and diagnostic services:
Transmit Table
Main Diagnostic Launch Table
- OFFLINE Mode
Frame List View
Signal List View
Trace List View
Status Bar
Additional to the View windows to monitor the CAN bus, there are several windows to configure and set

Status Bar
In each mode there can be Status Information windows displaying Status Information e.g. about the
buffer upload process.
CAT Application consists of an (opened) Session and a Database the session
points to. Another important part is the buffer content.
Main parts of a Session are:
- the link to a database,
- the layout settings for the graphical user interface (e.g. windows arrangements),
- the configurations of filter, trigger, transmit frames and diagnostics,
- the system setups for the buffer usage and for the connected CAN bus,
- the buffer content (when uploaded).
Main parts of a Database are:
- included vehicles,
- included ECU's,
- included Frames,
- included Signals.
Each vehicle contains ECU's, the ECU's contain Frames and Frames contain Signals.
Buffer
The total 50.000 frame buffer contains two parts:
- the Normal Buffer,
The normal buffer contains all CAN data that are received from the bus (unless there is no filter) and the data that are
transmitted by CAT.
- the Diagnostic Buffer.
The diagnostic buffer contains the diagnostic data that are received from the bus (unless there is no filter) and the
data that are transmitted by CAT.
See Buffer Handling for details.
