CFC
Typical response times and maximum number of ticks of the CFC task levels:
Task Level Time (in ms) Ticks CP300
Fast Event-Triggered
<1 3000
Event-Triggered
<10 15 006
Interlocking
<10 144 022 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 6MD85 Standard (double
busbar feeder with switchgear interlocking protection).
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
