Sample program
(H0803)
In this example, 2051 (H0803) is set in SW16. As a result, the quadrature bi-pulse
counter is selected.
When R010 comes ON, the data 150000 is set into the comparison value 1 register
(SW19×SW18), and 200000 is set into the comparison value 2 register (SW21×SW20).
While R010 is ON, the soft-gate (S240), the interrupt enable flag 1 (S241) and the
interrupt enable flag 2 (S249) are set to ON to enable the counter operation.
The count value is stored in SW23×SW22.
When R010 is OFF and R011 comes ON, the count value is preset to the data of
D0101×D0100.
