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.
The following table shows the effects of operating and programming condi-
tions on the operation of the timers.

TIM or TIMX(550) operates a decrementing timer with units of 0.1-s. The set-
ting range for the set value (SV) is 0 to 999.9 s for TIM and 0 to 6,553.5 s for
TIMX(550). The timer accuracy is 0 to 0.01 s.
Note The timer accuracy for CS1D CPU Units is 10 ms + the cycle time.
