CFC
Typical response times and maximum number of ticks of the CFC task levels:
Task Level Time (in ms) Max. Number of Ticks CP300
Fast Event-Triggered
< 1 1500
Event-Triggered
<5 (<10 ms) 12 397
Interlocking
<5 (<10 ms) 28 656 in total
Measurement
250
The times describe the response time of a typical CFC chart at the respective task level. The maximum number
of ticks applies to a typical load for the device based on the application template Fault recorder N6: 1/1, 43
BI, 33 BO, 20I, 20V
The task level Measurement runs in cycles every 500 ms. All other task levels are event-triggered.
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

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
