Result Interpretation

HMI-PLC Timing Alignment Ratio Validator calculator computes Timing Alignment Ratio in 1 using the defined engineering formula and the input values provided. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • HMI Screen Update Rate = 20
  • PLC Scan Time = 0.025

Expected Result:

  • Timing Alignment Ratio = 0.5

Engineering Interpretation:

Under the given input conditions, the calculated result is: Timing Alignment Ratio = 0.5.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
