*1

If the IOM Hold Bit (A500.12) has been turned ON, the status of timer Completion Flags and PVs will be maintained when
the operating mode is changed.

*2

The PV will be set to the SV when TIMH(015)/TIMHX(551) is executed.

When an operating TIMH(015)/TIMHX(551) timer is in a jumped program section (JMP(004),

CJP(510), JME(005)), the timer’s PV will not be refreshed in the above case.

When TIMH(015)/TIMHX(551) is in a program section between IL(002) and ILC(003) and the pro-

gram section is interlocked, the PV will be reset to the SV and the Completion Flag will be turned
OFF.

When a TIMH(015)/TIMHX(551) timer is forced set, its Completion Flag will be turned ON and its PV

will be set to 0000. When a TIMH(015)/TIMHX(551) timer is forced reset, its Completion Flag will be
turned OFF and its PV will be reset to the SV.

The timer’s Completion Flag is refreshed only when TIMH(015)/TIMHX(551) is executed, so a delay

of up to one cycle may be required for the Completion Flag to be turned ON after the timer times out.

If online editing is used to overwrite a timer instruction, always reset the Completion Flag. The timer

will not operate properly unless the Completion Flag is reset.

Sample program

When timer input CIO 0.00 goes from OFF to ON in the following example, the timer PV will begin
counting down from the SV (#0064 = 100 = 1.00 s). The Timer Completion Flag, T0000, will be turned
ON when the PV reaches 0.

When CIO 0.00 goes OFF, the timer PV will be reset to the SV and the Completion Flag will be turned
OFF.
