Accuracy of timer
instructions
Specification
± (10 ms + cycle time)
When operation is switched from duplex to simplex during timer instruction execution, the deviation in
the first cycle after switching may exceed the normal time, as shown below.
TIM, TIMX, TIMH(015), TIMHX(551), TTIM(087), TTIMX(555), TIML(542), TIMLX(553), MTIM(543),
MTIMX(554), TIMW(813), TIMWX(816), TMHW(815), TMHWX(817): (10 ms + cycle time) ± 10 ms or
less
TMHH(540), TMHHX(552): (10 ms + cycle time) ± 20 ms or less
PV refresh during
timer-system instruction
jump or while block program
is stopped (Different from
CS1-H.)
TIM, TIMX, TIMH(015), TIMHX(551), TMHH(540), TMHHX(552), TTIM(087), TTIMX(555):
The timer PV is not refreshed when the timer instruction is jumped for JMP, CJMP, or CJPN--JME. The
PV will be refreshed for the entire period it was jumped the next time it is executed (i.e., the next time it is
not jumped). (With CS1-H CPUs, the PV for these timers were refreshed even when jumped.)

(C200H Expansion I/O Racks and SYSMAC BUS Remote I/O Slave Racks cannot be connected.)
288 (cyclic tasks: 32; extra cyclic tasks: 256)
The extra cyclic tasks can be executed each cycle, just like the cyclic tasks, making a total of 288 tasks
that can be executed each cycle.
Cyclic tasks are executed each cycle and are controlled with TKON(820) and TKOF(821) instructions.
Supported (by global subroutines).
