Method of securing deterministic real time execution of multitask applications by calculating function of acquired parameter and comparing to set threshold value

摘要

A node is set to its initial level (0) (101), then a measured value v is acquired (102) and if it is smaller than s1 it returns to an initial setting. Otherwise the level is set (1) (104) for calculating a function t(v) (105). If the function value is less than s2 (106) a control returns to the initial level 101. Otherwise the control passes to the level (2) (107). A stage (108) sets an alarm condition with control returning to the initial level (101).
