19.24 Response
mes
The overall system must be taken into account when determining the response me following
a safety funcon request.
Parameter set acceptance from the SD card
Safe parameter set acceptance is supported by means of a safe parameter set saved in the
device.
The following are all crucial in determining the response me:
•
R
esponse
me of the connected safety sensor technology
•
Input delay of safety inputs
•
Internal processing me
•
When using a sa
fety bus:
-
Monitoring me for cyclic services
-
Monit
oring me in the safety PLC
-
Processing me in the safety PLC
