3.12 SI I/Os using fail-safe modules connected to PROFIBUS DP (840D from SW 6.3.30)
F-DO module
The NCK/PLC-SPL outputs $A_OUTSE/OUTSEP are logically combined in the
F driver to produce an F useful data signal (implicit 2v2 parameterization) and
mapped to the channels of the relevant F/DO module.

When parameterizing the PROFIsafe clock cycle, the DP cycle time determined
PROFIsafe cycle and
DP cycle time by the HW Config must be observed to ensure correct PROFIsafe
communications. Also refer to the following Chapter: Parameterizing the
SINUMERIK 840D NCK
After the station has been fully configured, the DP cycle time can be
determined by activating the isochronous bus cycle as follows:
In HW Config, open the properties dialog box of the PROFIBUS: DP master of
the configured station:
Dialog box Dialog box: Properties – DP Master system
( Note: Activate the equidistant bus cycle via the option field: "Activate
equidistant bus cycle/Recalculate equidistant time".)
( Note: The value calculated by HW Config and displayed in the field:
"Equidistant bus cycle" is the same as the DP cycle time)

Note
Mixed 2v2 and 1v1 parameterization within an F-DI module can reduce the
number of usable SPL input data $A_INSE/INSEP. It is therefore
recommended that 1v1 is first parameterized followed by 2v2.
