(TIML(542) and TIMLX(553) are reset to their set values, and MTIM(543)and MTIMX(554) are reset to 0.) Refer to the descriptions of these instructions for details.*2 If the IOM Hold Bit (A500.12) is ON, the PV and Completion Flag will be retained when a fatal error occurs orthe operating mode is changed from PROGRAM mode to RUN or MONITOR mode or vice-versa. The PV andCompletion Flag will be cleared when power is cycled. Refer to the CS/CJ/NSJ-series Instructions ReferenceManual (Cat. No. W474) for details.*3 If the IOM Hold Bit (A500.12) is ON and the IOM Hold Bit Check Box is selected in the Startup Hold Area onthe Startup Tab Page in the PLC Setup, the PV and Completion Flag will be retained when the PLC’s power iscycled.*4 The present values of HUNDRED-MS TIMER (TIM/TIMX(550)), TEN-MS TIMER (TIMH(015)/TIMHX(551)),ONE-MS TIMER (TMHH(540)/TMHHX(552)), TIMER WAIT (TIMW(813)/TIMWX(816), and HIGH-SPEEDTIMER WAIT (TMHW(815)/TMHWX(817)) timers programmed with timer numbers T0 to T2047 will be updatedeven when jumped between JMP and JME instructions or when in a task that is in WAIT status. The presentvalue of timers programmed with timer numbers T2048 to T4095 will be held when jumped or when in a taskthat is in WAIT status.• Timer Completion Flags can be force-set and force-reset.• There are no restrictions in the order of using timer numbers or in the number of N.C. or N.O. conditionsthat can be programmed.• The present data of all timers except for TENTH-MS TIMER (TIMU(541)/TIMUX(556)) and HUNDER-DTH-MS TIMER (TMUH(544)/TMUHX(557)) can be read as word data.6-32 CJ2 CPU Unit Software User’s Manual
