Note
1. TIM PVs are refreshed at execution, at the end of program execution each
cycle, or every 80 ms by interrupt if the cycle time exceeds 80 ms.
2. TIMH(015)/TIMHX(551) PVs are refreshed at execution, at the end of pro-
gram execution each cycle, and every 10 ms by interrupt.
3. TIMU(541), TIMUX(556), TMUH(544), and TMUHX(557) are supported by
CJ1-H-R CPU Units only.
4. It is not possible to read the timer PVs of TIMU(541), TIMUX(556),
TMUH(544), and TMUHX(557).
5. Timers are refreshed at different times depending on the timer number.
Refer to the descriptions of individual timer instructions for details.
The following table shows the effects of operating and programming condi-
tions on the operation of the timers.
