Program execution will continue even if a non-BCD SV is used, but the SV will
not be correct.
ER:
SV is not in BCD.
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.)
Ladder Symbol
SV is between 00.00 and 99.99. (Although 00.00 and 00.01 may be set, 00.00
will disable the timer, i.e., turn ON the Completion Flag immediately, and
00.01 is not reliably scanned.) The decimal point is not entered.
The EM area is available in CQM1H-CPU61 CPU Units only.
Each TIM/CNT number can be used as the definer in only one TIMER or
COUNTER instruction. Use TIM/CNT numbers from 000 through 015. High-
speed timers with timer numbers TIM/CNT 016 through TIM/CNT 511 should
not be used if the cycle time exceeds 10 ms.
TIMH(15) operates in the same way as TIM except that TIMH measures in
units of 0.01 second. Refer to 5-16-1 TIMER – TIM for operational details.
Timers in interlocked program sections are reset when the execution condition
for IL(02) is OFF. Power interruptions also reset timers. If a timer that is not
reset under these conditions is desired, SR area clock pulse bits can be
counted to produce timers using CNT. Refer to 5-16-2 COUNTER – CNT for
details.
Timers in jumped program sections will not be reset when the execution con-
dition for JMP(04) is OFF, but the timer will stop timing if jump number 00 is
used. The timers will continue timing if jump numbers 01 through 99) are
used.
High-speed timers with timer numbers TIM/CNT 000 through TIM/CNT 015
will not be inaccurate when the PC Setup (DM 6629) is set to perform inter-
rupt processing on these timers.
High-speed timers with timer numbers TIM/CNT 016 through TIM/CNT 511
will be inaccurate when the cycle time exceeds 10 ms. If the cycle time is
greater than 10 ms, use TIM/CNT 000 through TIM/CNT 015 and set
DM 6629 for interrupt processing of the timer numbers used.
Note The timer set value must be BCD between #0000 and #9999. Operation will
be as follows if #0000 or #0001 is set.
• If #0000 is set, the Completion Flag will turn ON as soon as the timer's
execution condition turns ON (but there may be a delay if TIM 000 to TIM
015 are used).
