3) Tp [ms] value
Tp = {(2 + 2 + 4 + 2)
= 38.1 [ms]
4) Scan [ms] value
Scan = 5 [ms]
5) Nand value
Nand = 3
From the above 1) to 4), Tscu [ms] is:
Tscu = TcpuA + Tsw + Tp + Scan
= 8 + 21.567 + 38.1 + 5
= 77.667 [ms]
Therefore, the redundant system switching time, Tsca [ms], is:
Tsca = Tscu + Nand 20
= 77.667 + 3 20
= 137.667 [ms]
