FB_MonthlyScheduler2

Function block for triggering actions on a certain day in certain months.

The function block triggers switching when the switching time is passed. Subsequent modification of the switching events or the time is therefore not permitted.

VAR_INPUT

arrActiveMonth   : ARRAY[1..12] OF BOOL;
uiActiveWeekday  : UINT;
eStartEnd        : E_StartEnd;
stStartEnd       : ST_StartEnd;
stSystemtime     : TIMESTRUCT;

arrActiveMonth: Month in which an action is to be triggered - arrActiveMonth[1]=>January ... arrActiveMonth[12]=>December. Multiple selections are possible.

uiActiveDay: Day of the month on which an action is to be triggered. Multiple selections are not possible.

eStartEnd: Selection of the start/end definition (see E_StartEnd).

stStartEnd: Structure with the parameters defining the start and end. Unused variables, for example the duration for the selection of start/end time, are ignored internally (see ST_StartEnd).

stSystemtime: Current time in TIMESTRUCT format. It is important to count every second.

VAR_OUTPUT

bOut              : BOOL;
bTriggerOn        : BOOL;
bNoEventNextYear  : BOOL;
bError            : BOOL;
nErrorId          : UDINT;

bOut: Control output that is switched on or off by the start and end event.

bTriggerOn: Trigger output for switch-on events. This output is intended for logging switch-on events. If two switch-on events occur consecutively they would not be detected via the control output bOut, since this output would remain TRUE. See also time overlaps in the overview.

bNoEventNextYear: No day matching the parameterization was found within the next 366 days.

bError: This output is set to TRUE if the parameterization is faulty. The command-specific error code is contained in nErrorId. Reset to FALSE once the parameterization is correct.

nErrorId: Contains the command-specific error code. Reset to 0 once the parameterization is correct. See Error codes.
