1.
Count up
• These function blocks count up (add "1" to) the value of (d2) when (s1) turns ON from OFF.
• When the value of (d2) reaches the value of (n) of the counter, (d1) turns ON and the function blocks stop counting up.
• Set the maximum value of the counter for (n). When (s2) is turned ON, (d1) turns OFF and (d2) is set to 0.
2.
Count maximum value
The effective setting range of (n) is from 0 to 32767.
