====== 6.3 Signal Oscilloscope ======

The signal oscilloscope is accessible directly from each trigger and timer configuration. It displays a real-time waveform of the selected IO-Link process data signal and allows the trigger level to be set visually. The scope reads from the same port and process data variable configured in the trigger or timer.

===== Controls =====

^ Control  ^ Description  ^
| Mode: Auto  | The scope re-arms automatically after each capture, continuously refreshing the waveform.  |
| Mode: Single  | Captures one waveform after the next trigger event, then holds.  |
| Mode: Manual  | Does not arm automatically; use the "Force" button to capture regardless of trigger condition.  |
| Force button  | Immediately captures the current signal. Available in Manual mode only.  |
| Trigger Level  | Adjusts the threshold at which the scope triggers. Changes take effect after immediately |
| Save | Explicitly saves the current trigger level back to the trigger or timer configuration on the settings page.  |
| X (Close button)  | Closes the scope and stops acquisition.  |

===== Technical Notes =====

  * The scope samples at a 10ms interval.
  * A pre-trigger buffer shows signal history before the trigger event.
  * Trigger level changes made in the scope are reflected in the trigger or timer configuration form after pressing "Save".
