(2) Operation example of the count disable/preset/replace function
The following figure shows an operation example of stopping counting while CH  Function input terminal
(FUNC1, FUNC2) is on and storing the preset value (0 or 100) in CH  Present value (RWr10 to RWr11, RWr28
to RWr29) at the falling edge of CH  Function input terminal (FUNC1, FUNC2).

No. Description
1) Counting starts by turning on CH  Count enable command (RY24, RY3C).
2) Counting stops at the rising edge of CH  Function input terminal (FUNC1, FUNC2).
3)
The value in CH  Preset value setting (RWw14 to RWw15, RWw2C to RWw2D) is stored in CH  Present value (RWr10 to RWr11,
RWr28 to RWr29) at the falling edge of CH  Function input terminal (FUNC1, FUNC2), and the counting resumes.
4) Set any values to CH  Preset value setting (RWw14 to RWw15, RWw2C to RWw2D).
5) Counting stops by turning off CH  Count enable command (RY24, RY3C).
6)
Counting stops regardless of CH  Function input terminal (FUNC1, FUNC2) since CH  Count enable command (RY24, RY3C) is
off.
7)
Counting remains stopped even if CH  Count enable command (RY24, RY3C) is turned on since CH  Function input terminal
(FUNC1, FUNC2) is on.
8)
The value in CH  Preset value setting (RWw14 to RWw15, RWw2C to RWw2D) is stored in CH  Present value (RWr10 to RWr11,
RWr28 to RWr29) at the falling edge of CH  Function input terminal (FUNC1, FUNC2), and the counting resumes.
