Description
ret_val := SET_TINTL(
OB_NR:=_int_in_,
SDT:=_dtl_in_,
LOCAL:=_bool_in_
PERIOD:=_word_in_

Set a date and time of day interrupt. The
program interrupt OB can be set for one
execution, or for recurring execution with
an assigned time period.
Table 9- 108 Data types for the parameters
Parameter and type
Data type
Description
OB_NR
IN
OB_TOD (INT)
OB number (accepts symbolic name)
SDT IN DTL Start date and time: Seconds and milliseconds are ignored and can be
set to 0.
LOCAL IN Bool 0 = Use system time
1 = Use local time (if the CPU is configured for local time, otherwise
use system time)
PERIOD IN Word The period from the starting date and time for recurring interrupt event.
• W#16#0000 = Once
• W#16#0201 = Every minute
• W#16#0401 = Every hour
• W#16#1001 = Daily
• W#16#1201 = Weekly
• W#16#1401 = Monthly
• W#16#1801 = yearly
• W#16#2001 = End of month
ACTIVATE IN Bool 0 = ACT_TINT must be executed to activate the interrupt event.
1 = The interrupt event is activated.
RET_VAL
OUT
Int
Execution condition code
Your program can use SET_TINTL to set a date and time of day interrupt event that will
execute the assigned interrupt OB. The start date and time is set by parameter SDT and the
time period for recurring interrupts (for example, daily or weekly) is set by parameter
PERIOD. If you set the repetition period to monthly, then you must set the start date to a day
from 1 to 28. The days 29 to 31 may not be used because they do not occur in February. If
you want an interrupt event at the end of each month, then use end of month for parameter
PERIOD.
