Components of
the calculation
Description
Value [ms]
2. Logic
a) Response time
of the main module
logic
2 × logic execution time
Take the value from the report in the
configuration software.
Delay due to logic application (e.g.
switch-on delay or switch-off delay
function block)
Take the value from the report in the
configuration software.
b) Response time of
the routing
For OUT3 output to the gateway only
Delay: 8 ms
c) Response time of
the fast shut off logic
No delay time
0
3. Outputs
Response time of the
observed output in
the signal path
OUT1, OUT2, OUT3, OUT4 or OUT5

Description
Value [ms]
Always
Input processing time
3
ON-OFF debounce filter is configured. Min. debounce filter time
Take the value from the report in the con‐
figuration software.
Input element is connected to a test
output (X).
Max. tolerated test pulse delay
Take the value from the report in the con‐
figuration software.
Input element is connected to a test
output (X).
•
For safety sensors with a test input or
Flexi Loop: test pulse frequency of the
test output
•
For safety pressure mats: the longer
test pulse frequency of the two test
outputs
•
For electro-mechanical switch/safety
switch (EMSS): test pulse duration of
the test output

Description
Value [ms]
IN3
When using a gateway.
2 × internal update interval (4 ms) - 2 ms
= 6 ms
IN4
When using Modbus® TCP
or SLMP.
2 × internal update interval (20 ms) -
2 ms
= 38 ms
