CFC
Typical response times and maximum number of ticks of the CFC task levels:
Task Level Time (in ms) Ticks CP200 Ticks CP300

gered
<1 500 1000
Event-Triggered
<10 13 254 15 359
Interlocking
<10 128 873 in total 149 603 in total
Measurement

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 Basics.
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
+ ∑

where:
n
Inp
Number of indications routed as input in the CFC chart

Outp
Number of indications routed as output in the CFC chart
