Trigger
CAT allows defining a Trigger Event based on Frame Identifier and Data. This Trigger is used to set a flag into the
logged buffer and to stop the logging of data. Therefore the user can define by Pre/ Post Trigger how many frames
shall be stored before and after the trigger event occurs.
The feature Time Out Trigger allows to trigger on the lacking of a frame. To use a frame from the database there is an
easy access button to the frame list. (See Trigger on existing Frames)
Choose menu item Configurations | Trigger from the main window to open the Trigger
Configuration... window shown above.
Enable Trigger: Click into this box and get it marked to enable triggering on the defined conditions. Otherwise the
occurrence of a defined frame will have no influence to the logging process at all.
Note: Enable trigger has to be marked to enable the input or edit from all other
input fields in this dialog.
The trigger sign in the status bar becomes yellow when Trigger is enabled.
Use Frame List : Click this button to access the Frame List allowing choosing one or more predefined Frame. Then
the frame ID, format, number of data bytes and the default data will be implemented automatically in order to create a
trigger condition.
Format: Choose standard (STD 11bit Identifier) or extended (XTD 29bit Identifier) format.
Number
of Data Bytes: Choose the number of data bytes that the trigger condition to be triggered on must have.
Tip: Input "0" to trigger only on the Identifier. The Data Bytes will not be
considered as trigger condition.
Note: If a frame contains more data bytes then required it still is a trigger condition
as long as the data bytes, which are required, fulfil the Data Byte Trigger conditions
described below.
