Omron SYSMAC CV Series - Timer: Tim

142
The first MOV(030) instruction moves the PC memory address of the PV for tim-
er T0000 ($1000) to IR0. The first MOVR(036) instruction moves the PC
memory address of the Completion Flag for timer T0000 to IR1, and the second
one moves the starting address into IR2. The second MOV(030) instruction
moves the address (00100) of the DM word that contains the SV for timer T0000
to D00000. A50013 is an Always ON Flag.
JME(005) and JMP(004) form a loop in which the content of IR0, IR1, and
D00000 are incremented by one each time the program executes the loop,
successively defining and starting the 100 timers T0000 through T0199. The
loop continues until the content of D00000 is 0200, i.e., until all 100 timers have
been defined and started. A50006 is the Equals Flag.
The subroutine above is equivalent to the 400 instructions below.

Description A timer is activated when its execution condition goes ON and is reset (to SV)
when the execution condition goes OFF. Once activated, TIM measures in units
of 0.1 second from the SV. TIM accuracy is +0.0/–0.1 second.
The timer PV is updated when the TIM instruction is executed, during cyclic re-
freshing, or interrupt refreshing (when the cycle time exceeds 80 ms). Refer to
6-2 Cycle Time for details.
If the execution condition remains ON long enough for TIM to time down to zero,
the Completion Flag for the timer number used will turn ON and will remain ON
until TIM is reset (i.e., until its execution condition goes OFF or CNR(236) is
executed).
