(H1003)

In this example, 4099 (H1003) is set in SW16. As a result, the single phase up-counter (channel 1 only) is selected.

When R010 comes ON, the data 2000 is written into the set value register (SW18). While R010 is ON, the soft-gate (S240) and the interrupt enable flag (S241) are set to ON to enable the counter operation.

The counter works as a ring counter with the set value 2000. The count value is stored in SW22.

When R010 is OFF and R011 comes ON, the count value is preset to the data of D0100.
