The operation of the = Flag and N Flag depends on the model of the CPU
Unit. Refer to Flags, above, for details.
If online editing is used to convert a timer to another kind of timer with the
same timer number (such as TMHH(540)/TMHHX(552) ↔ TIM/TIMX(550) or
TMHH(540)/TMHHX(552) ↔ TIMH(015)/TIMHX(551)), be sure to reset the
Completion Flag. The timer will not operate properly unless the Completion
Flag is reset.
A TMHH(540)/TMHHX(552) instruction's PV and Completion Flag are
refreshed as shown in the following table.

TTIM(087)/TTIMX(555) operates an incrementing timer with units of 0.1-s.
The setting range for the set value (SV) is 0 to 999.9 s for TTIM(087) and 0 to
6,553.5 s for TTIMX(555). The timer accuracy is –0.01 to 0 s.
Note The timer accuracy for CS1D CPU Units is 10 ms + the cycle time
