BUSMASTER E2E: Send periodically, reset counters and save projects

The transmit row’s existing channel, CAN ID, frame type, length, period and send count controls apply to E2E-protected frames.

1. Run a finite periodic transmission

1. Stop any active task and disconnect CAN.
2. Select the 0x2A0 row from chapter 01. Verify P01 / BOTH, DataID 0x0123, first counter 0, eight zero bytes, counter 8 / 4 / Intel and checksum 0 / 8 / Intel.
3. Set Send Count to 4 and the Repetition period to 200 ms.
4. Select the checkbox for this row’s period. Leave the other teaching rows cleared.
5. Prepare the receiver and click Connect. The enabled periodic row starts automatically.
6. Check the four frames, their counter order and complete payloads on the receiver. Wait for the finite task to finish.

Clicking Send Message during the periodic task adds a manual transmission. In the X1 teaching setup, the receiver recorded the four payloads from chapter 01 and no fifth frame during an eight-second observation.

Clear Repetition to pause a row. Click Disconnect to end the session. Use the period and send count specified by the project on a production network.

2. Continue or reset the counter

Operation	Effect
Send again on the same connection, or resume after stopping the periodic row	Continue from the accepted protection state.
Click Reset in the row’s E2E settings	Start from the configured first counter.
Change an effective parameter	Initialize from the new configuration.
Confirm the same value or cancel the selection	Keep the current count.
Create or load a project, or disconnect and reconnect	Initialize the runtime state.
Remove an algorithm from the manager	Preserve existing rows’ settings and runtime state.

Reset applies to the selected transmit row. To start the next frame from its first counter, stop periodic transmission before clicking Reset. If a transmission fails or its outcome is unclear, stop the periodic task and compare the diagnostic log with the capture for that time.

3. Save and reopen a CFX project

Use Save or Save As. A CFX stores the algorithm list, selected algorithms and parameters, signal sources and transmit settings. Runtime Context and counter progress are initialized on load.

1. Stop the task, disconnect and save to a named CFX.
2. Reopen the project while offline.
3. Check each row’s ID, channel, type, length, dynamic message, DataID, first counter and sources.
4. Verify the period checkboxes and send counts before reconnecting.
5. Check dependencies, then connect and send.

4. Move a project

Keep the referenced DBC files and external DLLs with the CFX. Check relative and absolute references after moving or saving the project to a new location. On another PC, verify logical channels are mapped to the correct analyzer ports. If an external DLL cannot be found, restore the referenced file before sending. See DLL setup.
