SNVT Setting (FbSetting)Function Description:The function block “Setting” transforms the input values of a SNVT_Setting into shortor long output pulses. The length of the output pulses can be set via the inputs“dwTK_10tel_s“ (short pulse) or “dwTL_10tel_s“ (long pulse). After evaluation ofthe signals at the inputs bFunction, bSetting and iRotation, the pulse will be outputat xUP or xDOWN.In combination with the function block “sunblind” it is thus possible to generate thecommands UP / DOWN / STOP as well as slat regulation UP/DOWN.The times uiTK_10tel_s and dwTL_10tel_s need to be adjusted to the time settingdwT_TasKurzIn10telSec of the function block “sunblind”.The following has to be observed:dwTK_10tel_s < uiT_SwitchShortIn10telSec (FbSunblind:time for short keystroke)dwTL_10tel_s > uiT_SwitchShortIn10telSec (FbSunblind: time for long keystroke)Example:The bSetting and iRotation values may be disregarded in most applications. Bothinput values then have to be constant values.bSetting = 16#00iRotation = 16#7fffThe bFunction element is set as follows in the Plug In PRIO:TimeOut time approx.500msExample from WAGO I/O PRO:Subject to design changes WAGO Kontakttechnik GmbH & Co.
