enable

Short summary​

Enables stepping mode for the cycle manager sequence.

Purpose and usage​

This method enables the stepping mode functionality for the entire cycle manager sequence. When stepping is enabled, the cycle execution pauses after each step, requiring manual trigger or auto-step delay before proceeding to the next step.

Stepping mode is essential for:

  • Commissioning new sequences
  • Debugging sequence logic
  • Training operators
  • Validating step transitions

typical usage patterns​

  1. Commissioning: Step through new sequences manually
  2. Debugging: Examine state between steps
  3. Training: Demonstrate sequence flow to operators
  4. Validation: Verify each step executes correctly

When to use​

  • During initial commissioning of new equipment
  • When debugging sequence problems
  • For operator training sessions
  • During sequence development and testing
  • When validating modifications to sequences

Example​

// Enable stepping for commissioning
cycleManager.configuration.configuration.sequence
    .stepping
    .enable();

// Enable stepping with auto-advance
IF debugMode THEN
    cycleManager.configuration.configuration.sequence
        .stepping.enable();
    cycleManager.setAutoStepDelay(T#2S);  // Auto advance every 2 seconds
END_IF;

// Manual step control
IF cycleManager.steppingEnabled THEN
    IF HMI.StepButton.Pressed THEN
        cycleManager.triggerStep();  // Advance to next step
    END_IF;
END_IF;

// Show stepping controls in HMI
IF cycleManager.steppingEnabled THEN
    HMI.StepButton.Visible := TRUE;
    HMI.CurrentStep.Text := INT_TO_STRING(cycleManager.steps.current);
    HMI.NextStep.Text := INT_TO_STRING(cycleManager.steps.next);
END_IF;
