Outline of operation
● Unlike the CT instruction, the range available for the setting value [S] for this instruction is U0
to U65535.
● All counters are decremental preset counters.
● When the reset input falls from OFF to ON, the value in the setting value area CS is preset to
the elapsed value area CE.
● When the reset input is ON, the elapsed value is reset (cleared to zero). When the count
input changes from the OFF state to the ON state, the setting value is subtracted. When the
elapsed value becomes U0, it is output to the counter contact.
● If the count input and reset input both turn ON at the same time, the reset input is given
priority.
