@SavinoLupo  MC33772C hello Savino, our customer have below SM relation questions, please help check. 1. For the diag_time and recv_time of SM_01, SM_02, SM_36, it didn’t specify how they are calculated. We tried to use the formula in the safety manual, but we can’t get the same result as that in the xlsx tool. If you use different formula, or there are other coefficient contributed to the result ? 2. Regarding to diag_time of SM_36, in the safety manual, it states that it is dependent on the VISENSE_OL, Imax and IISENSE_OL，but in the xlsx tool, during calculation, it didn’t include all of these parameters, why ? 3. Regarding to diag_time of SM_36, in the safety manual, it’s specified to take 32ms, but in the xlsx tool, it’s specified to take 64ms, what’s the reason ?
