The following table shows when timer PVs and Completion Flags will be
reset.
Effect on PV and Completion Flag
1
Mode change PLC start-up
PV → 0 PV → 0
Flag → OFF Flag → OFF
1. If the IOM Hold BIt (A50012) is ON, the PV and Completion Flag will be
retained when a fatal error occurs or the operating mode is changed from
PROGRAM mode to RUN or MONITOR mode or vice-versa. The PV and
Completion Flag will be cleared when power is cycled.
2. If the IOM Hold BIt (A50012) is ON and the PLC Setup's "IOM Hold Bit Sta-
tus at Startup" setting is set to protect the IOM Hold Bit, the PV and Com-
pletion Flag will be retained when the PLC's power is cycled.
3. Since the TIML(542), TIMLX(553), MTIM(543), and MTIMX(554) instruc-
tions do not use timer numbers, they are reset under different conditions.
Refer to the descriptions of these instructions for details.
4. The present value of TIM, TIMX, TIMH(015), TIMHX(551), TMHH(540),
TMHHX(552), TIMW(813), TIMWX(816), TMHW(815), and TMHWX(817)
timers are held when the timer is jumped between JMP and JME instruc-
tions or when in a task that is on standby.
Timer Completion Flags can be force-set and force-reset.
Timer PVs cannot be force-set or force-reset, although the PVs can be
refreshed indirectly by force-setting/resetting the Completion Flag.
