Program example
■CTUD(_E)
The program which counts the number of times that bit type data input to (s1) is turned from OFF to ON, and turns ON (d1)
when the value of (D3) reaches the value set at (n). Simultaneously, it counts the number of times that bit type data input to
(s2) is turned from OFF to ON, and turns ON (d2) when the value of (D3) reaches 0.
