The ID trap is particularly useful for two purposes. First, you can use it to read out the identifiers of messages present on the bus and count their frequency within set time interval. Second, it can help you to identify asynchronously generated message due to an event or status change. Press Run to start the measuring; the data in the tree is refreshed based on selected time interval. Once a message is captured that is not present in the list, the identifier of that message is put in the list and the counter is set to one. Next time the message occurs, the counter is increased by one. After the specified time interval passed, all the counters are reset to zero. Messages not present in the just passed interval, i.e. with zero-value of the counter, however present on the bus in previous intervals, are displayed with a red spot. Messages with a non-zero counter value have a green spot. The blue spot stands for an identifier, that has been captured for the first time on the bus. Press the Stop button to stop measuring and evaluate the data. Press the Reset button to clear the message tree; the tree starts to create again next time the measuring starts.
