Conversion Instructions Section 5-20
5-20-13 HOURS-TO-SECONDS – SEC(––)
Limitations S and S+1 must be within the same data area. R and R+1 must be within the
same data area. S and S+1 must be BCD and must be in the proper hours/
minutes/seconds format.
DM 6143 to DM 6655 cannot be used for R.
Description SEC(––) is used to convert time notation in hours/minutes/seconds to an
equivalent in just seconds.
For the source data, the seconds are designated in bits 00 through 07 and the
minutes are designated in bits 08 through 15 of S. The hours are designated
in S+1. The maximum is thus 9,999 hours, 59 minutes, and 59 seconds.
The result is output to R and R+1. The maximum obtainable value is
35,999,999 seconds.
Flags ER: S and S+1 or R and R+1 are not in the same data area.
S and/or S+1 do not contain BCD.
Number of seconds and/or minutes exceeds 59.
Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
EQ: ON when the result is zero.
Example When 00000 is OFF (i.e., when the execution condition is ON), the following
instruction would convert the hours, minutes, and seconds given in HR 12 and
HR 13 to seconds and store the results in DM 0100 and DM 0101 as shown.
S: Beginning source word (BCD)
IR, SR, AR, DM, EM, HR, TIM/CNT, LR
R: Beginning result word (BCD)
IR, SR, AR, DM, EM, HR, TIM/CNT, LR
