ONE-MS TIMER: TMHH(540)/TMHHX(552)
Purpose
TMHH(540)/TMHHX(552) operates a decrementing timer with units of 1-ms.
The setting range for the set value (SV) is 0 to 9.999 s for TMHH(540) and 0
to 65.535 for TMHHX(552). The timer accuracy is –0.001 to 0 s.
Note The timer accuracy for CS1D CPU Units is 10 ms + the cycle time
