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. |
