12.2.1 Calculation of the response time
The following table can be used to calculate the response time of associated paths
w
ithin the Flexi Soft system.
Table 97: Calculation of the maximum response time of the Flexi Soft system in milliseconds
1. Inputs Response time of the input
under c
onsideration on the
signal path
E1 or E2 or E3 or E4 or E5
(see corresponding table)
2. Logic a) Response time of the
logic of the main module
(FX3-CPUx logic)
2 × logic execution time
1)
Delay with logic application
2)
(e.g., switch-on delay
or switch-off delay function
block)
b) Response time for rout‐
in
g (only affects A3 output
to gateway)
No delay 0 ms
c) Response time of the
fast shut-off logic (only
applicable for FX3-XTIO
modules)
No delay 0 ms
3. Outputs Response time of the output
under consideration on the
signal path
A1 or A2 or A3 or A4 (see
corresponding table)
Total response time
1)
Take values from the configuration software report.
2)
Time values have a tolerance of 10 ms in addition to the logic execution time; i.e., 10 ms must be added
t
o each selected value in order to calculate the response time. For example, in the case of a switch-off
delay of 10 ms and a logic execution time of 12 ms, 32 ms must be used for the calculation.

Total E1
1)
Take value from the corresponding operating instructions.
2)
Switching off is delayed until the signal has been at Low for at least the selected filter time. For FX3-XTIO
and FX3-
XTDI firmware version < V3.00.0, the filter time is set to a fixed value of 8 ms.
3)
Take values from the configuration software report.
