Re: Why Should the Watchdog Time (F_WD_Time) Not Be More Than 130% the Minimum Time?

The PROFIsafe Profile states in section 'Adjustment of watchdog times for FSCP 3/1': It is highly recommended that the difference between the assigned parameter value F_WD_Time and the sum (DAT, HAT, and bus transmission delays) does not exceed 30 %. Why is this the case? In section 'Calculation an...
