Program examples
1. Program example 1
In the program example below, the current value of the high-speed counter C235 is compared in each operation cycle,
and then the output Y000 is set to ON if the current value is "K500" or more (when the current value of C235 is not
cleared).
*1. K0: The current value of the high-speed counter is not cleared when DHCMOV instruction is executed.
K1: The current value of the high-speed counter is cleared when DHCMOV instruction is executed.
2. Program example 2
In the program example shown below, the current value of C235 is transferred to D201 and D200, and the current
value of C235 is cleared when X001 turns from OFF to ON.
*2. K0: The current value of the high-speed counter is not cleared when DHCMOV instruction is executed.
K1: The current value of the high-speed counter is cleared when DHCMOV instruction is executed.

When X001 turns from OFF to ON, the
interrupt program from I101 to IRET is
executed.
The current value of C235 is
transferred to D201 and D200.
(The current value of C235 is cleared
to “0”.)
