7.5 Response times of the PROFIsafe devices
Response time of KP8F
The response time of the HMI device enters into the calculation of the response time of the
F-system.
● Response times of the fail-safe channels
● Response time of the HMI device
The following image shows where response times can be expected.

The response time is the time that is required between a signal change on the digital
input and the safe loading of the safety message frame to PROFINET.
The actual response time is somewhere between the shortest and longest response time.
When planning a system, the longest response time must always be anticipated.
Information about the response time can be found in the chapter "Technical specifications
(Page 84)".
