TIMM(20) operates in the same way as TIM except that TIMM(20) measures
in units of 0.01 second.
Refer to 3-7-14 TIMER - TIM for operational details and examples. Except for
the above, and all aspects of operation are the same.
Timers in interlocked program sections are reset when the execution condi-
tion for IL(02) is OFF. Power interruptions also reset timers. If a timer that is
not reset under these conditions is desired, dedicated clock pulse bits can be
counted to produce timers using CNT. Refer to 3-7-18 COUNTER - CNT for
details.
Flags
ER:
The Error Flag (0311) will be turned ON when the SV is set in a word
(SP16 and SP20 only) but the content of the indicated word is not
BCD. The instruction will be executed, but operation will not be reli-
able.

SV: Set value (BCD)
SP10: #
SP16, SP20: I/O, work, DR, LR, #
Operand Data Areas
SV is between 0.000 and 9.999 seconds. The decimal point is not entered. In
practice, the accuracy of TIMH(21) is limited to the scan time (i.e., because
outputs are refreshed only once each scan, the accuracy of TIMH(21) is lim-
ited to the order of magnitude of the scan time). Refer to 3-9 Program Execu-
tion for details on the scan time.
The TC number is automatically set to TIM 14 when TIMH(21) is designated
and does not need to be input.
TIMH(21) operates in the same way as TIM and TIMM(20) except that
TIMH(21) measures in units of 0.001 second.
