SICK Flexi Compact, Operating Instructions Manual

Page: 137 / 156

When relevant? Description Value [ms]
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

Table 157: OUT3 … OUT5 - Response time for processing of outgoing process data
When relevant? Description Value [ms]
OUT3 When using a gateway. 2 × internal update interval (4 ms) – 3 ms
= 5 ms 5
OUT4 When using Modbus® TCP
or SLMP. 2 × internal update interval (20 ms) –
3 ms
= 37 ms –
OUT5 When using Flexi Loop on
the expansion module (ser‐
vice data). 2 × internal update interval (56 ms) -
1 ms
= 111 ms –

Table 158: Calculating the maximum response time – signal path 2
Components of
the calculation Description Value [ms]
1. Inputs Response time of the
observed input in the
signal path IN1, IN3, IN4 or IN5
•
see table 156, page 136
3
2. Logic a) Response time
of the main module
logic 2 × logic execution time
Take the value from the report in the
configuration software. 8
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
No delay time 0
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
