Description
1) Conversion to the number of seconds from standard time *1 is performed for the input time data [S ~
S+2], and a conversion result is stored in [D, D+1] by the 32−bit binary.
2) The conversion is in consideration of the leap year.
1 minute −−− 60 seconds
1 hour −−− 60 minutes
1 day −−− 24 hours
1 year (leap year) −−− 366 days
1 year (except a leap year) −−− 365 days
A leap year (4 multiple years) −−− Feb.29
3) Time data (S) must be specified in the data sequence of BCD, and the value within the limits must be
registered.
*1: Standard time is 00:00’00” on January 1, ’01.
Moreover, a conversion result is output with a binary value.

Flag conditions
ΣError flag (R9007) (R9008):
− It turns on, when the specified address using the index modifier exceeds a limit.
− It turns on, when values other than BCD are specified for [S].
− It turns on, when the value which exceeds the range in the time data of [S]
is specified.
− It turns on, when the data of [S] exceeds the area.
