stepWidth

Short summary

Sets the step width for automatic step increment for the current step.

Purpose and usage

This property sets the increment value used when automatically advancing from the current step. It overrides the sequence default step width for this specific step. When no explicit next step is specified, the cycle manager will advance by this step width value.

This allows individual steps to have different increment values, useful for:

• Skipping blocks of steps
• Jumping to different sequence sections
• Implementing conditional branching
• Custom step numbering schemes

typical usage patterns

1. Skip sections: Large step width to jump over optional sections
2. Branch control: Different widths for different branches
3. Return jumps: Negative values to go back in sequence
4. Custom flow: Implement complex sequencing logic

When to use

• When this step needs to jump to a non-sequential next step
• For implementing branching logic
• To skip optional sequence sections
• When overriding the default sequential flow

Example

// Configure step to skip optional section
CASE cycleManager.steps.current OF
    100:  // Decision step
        IF skipOptionalSteps THEN
            // Jump to step 200, skipping 110-190
            cycleManager.configuration.configuration.step
                .stepWidth := 100;
        ELSE
            // Normal increment to 110
            cycleManager.configuration.configuration.step
                .stepWidth := 10;
        END_IF;
        cycleManager.steps.next := 0;  // Use automatic increment
        
    190:  // Last optional step
        // Ensure we continue at 200
        cycleManager.configuration.configuration.step
            .stepWidth := 10;
        cycleManager.steps.next := 0;  // Automatically goes to 200
        
    250:  // Loop back step
        IF repeatRequired THEN
            // Go back to step 200
            cycleManager.configuration.configuration.step
                .stepWidth := -50;
            cycleManager.steps.next := 0;  // Automatically goes to 200
        END_IF;
END_CASE
