CFC
In order to estimate the tick consumption of a CFC chart, you can use the following formula:
T
Chart
= 5 ∙ n
Inp
+ 5 ∙ n
Outp
+ T
TLev
+ ∑
i
T
int
+ ∑
j
T
Block
where:
n
Inp
Number of indications routed as input in the CFC chart
n
Outp
Number of indications routed as output in the CFC chart
T
TLev
101 Ticks in Fast Event-Triggered level
104 Ticks in Event-Triggered level
54 Ticks in Measurement level
74 Ticks in Interlocking level
T
