System response times
888550283
The response time is the time that is required to activate the safety function.
Example: The time from which the safety light barrier is crossed until the machine stops.
In order to determine the response time of the samosPROsystem, use the standard time plus
the filter and test times.
Factor 1: Standard time
Maximum ON-OFF time from input to output without filter and test times:

FSO SP-COPx
2 x cycle time + 6.9 ms
2 x cycle time + 10.6 ms
Output SP-SDIO
--
8.6 ms
FSO SP-SDIO
• The cycle time must be obtained from samosPLAN
6 (lower right).
• FSO = Fast Shut-Off: This function can be used to achieve quicker switch-off times from
input to output inside the module. FSO is a functional component in the samosPLAN
6.
Factor 2: Filter time
When the ON-OFF filter is activated, the switch-off signal is delayed by the filter time set. This
filter can be activated for each input in the samosPLAN
6 and acts upon the response time with
+
8 ms.
Factor 3: Test times
If the input tests are carried out in single-channel input circuits with the assistance of tests
outputs T1 to T4 or X1 to X8, this results in the response time for test times > 1 ms from the
test time plus response time (wait time until the test pulse occurs).

When using user-defined elements (software manual) the response time can also be extended
in two-channel input circuits if the selected test time is greater than 0.5 * test period minus
12 ms. The resulting additional response time should be calculated as follows:
additional response time = test time + 12ms - 0.5 * test period
(Only a positive result is evaluated, negative values are equal to zero)
For applications with a safety mat, the test period of the test generators connected must be
applied to the response time. The following table provides the reaction times for the corres-
pondingly set test periods.
ATTENTION
Changed reaction times!
From build state D 03.01 of the SP-COP modules and B 08 of the SP-SDIO modules, the lon-
ger response times given in the table below apply.
In particular, for existing projects with sensor elements for safety mats and bumpers, this
extension of the response times must be adhered to (e.g. in the case of replacement of a SP-
COP module).
