Arithmetic Instructions
Applications of TMIN (Analog timer) instruction
■ Changing timer setting value
Uses analog timer (TMIN0) to change the timer setting value (0 to 24.9 s).
Ladder diagram Coding
■ Changing setting values of multiple timers
Uses analog timer (TMIN0) to change setting values of multiple timers (0 to 24.9 s).
Ladder diagram Coding
* In the above example, T000, T001,
and T002 have the same setting value.
➮ Refer to p. 3-138.
Applications of LDA/STA instruction
■ First-in first-out (FIFO)
