Abstract
Safety function response time is a metric for safety-critical automation systems defined in the IEC 61784-3-3 standard for single input and single output systems communicating over wired technologies. We propose a model to estimate the safety function response time for a multiple input and multiple output feedback control loop system communicating wirelessly over one of the modes defined in the IEEE 802.15.4e standard that was specifically designed for process automation. Our model merges the architecture and safety requirements defined in the IEC 61784-3-3 standard with the communication protocol defined in the IEEE 802.15.4e standard. We present equations for the worst case delay time and watchdog timer of the participating network entities, and demonstrate the application of our model via an example of a multiple input and multiple output system implementing a feedback control loop.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
