Siemens SIMOTION D410-2DP/PN Installation Manual page 243

Note
If SIMOTION D410‑2 is mounted separately (Power Module connected to SIMOTION D410‑2
via CUA31/32), use of the Safety Integrated Extended Functions via the on-board terminals
(F-DI, F-DO) is not possible.
F-DI and F-DO as standard I/Os
Unused F‑DI and F‑DO can be used as standard I/Os (one F‑DI as two standard inputs, the
F‑DO as a standard output).
Using F-DI through F-CPU
Prerequisite for use of the F‑DI by F‑CPU:
● With encoder as of SIMOTION V4.3 SP1 HF3
● Without encoder as of SIMOTION V4.4
The onboard F‑DIs can be used as F‑DI for the F‑CPU if these are not used by
SIMOTION D410‑2.
In "Extended functions via PROFIsafe and basic functions via terminal" mode, the basic
functions STO or SS1 (with or without SBC) can be controlled locally. At the same time the
routing of F‑DI 1 and F‑DI 2 for the F-CPU is possible.
Filter setting F‑DI
The F‑DIs of SIMOTION D410‑2 have a parameterizable input filter (drive parameter p10017,
debouncing time for digital inputs).
With this input filter, unwanted signals (e.g. fault signals or test pulses of F-DO) can be filtered
out so that these do not cause any faults.
Failsafe output modules (e.g. ET 200S F-DO) test the outputs at regular intervals. To achieve
this, the F-DO modules switch test signals to their outputs in the form of bit patterns to detect
a short-circuit, short-circuit to frame, or a short-circuit to ground.
If the filter time of the F-DI is set too small, these test pulses will result in unwanted triggering
of the safety function in the case of D410-2.
For setting the input filter, the following rules must therefore be complied with:
● Debouncing time p10017 ≥ 3 x sampling time inputs/outputs p0799
● If 3 x p0799 < 1 ms, then: Debouncing time p10017 = N x 1 ms (N = 1, 2, 3, ...)
● Debouncing time p10017 >> fault pulse time
Unwanted triggering of the safety function can indicate incorrect settings.
Note that the settings also impact the reaction time of the system.
Example
ET 200S I/O system with F‑DO modules
Because of the test pulses, the debouncing time p10017 must be at least 4 ms.
