Response times
Overview
The total response time of the application depends on the:
•
Basic response time at the related resolution and the maximum protective field
range
•
Set multiple sampling
•
OSSDs used
S
Calculating the total response time T
S
b
The total response time T
S
is calculated using the following equation:
T
S
= t
B
+ T
MFA
+ T
EFIO
where
•
t
B
= Basic response time (60 ms or 120 ms)
•
T
MFA
= Supplement due to multiple sampling > 2
•
T
EFIO
= Supplement for the usage of external OSSDs via EFI
Multiple sampling
Multiple sampling is always set to at least 2 on the device. For a multiple sampling of 3
or above, a supplement must be added to the response time. The related supplement is
dependent on the basic response time and the multiple sampling.

External OSSDs
If the OSSDs on another device are used via EFI interface as external output signal
switching devices (for example with two safety laser scanners connected together), the
response time increases by 20 ms in each case.
