Typical response times and maximum number of ticks of the CFC task levels:
Task Level
Fast Event-Triggered
Event-Triggered
Interlocking
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 Unit connection extended.
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 = 5 ∙ n
Chart
where:
n Number of indications routed as input in the CFC chart
Inp
n Number of indications routed as output in the CFC chart
