• Write the following program to "reset only the current value of a high speed counter (and does not turn OFF the 

contact)".

1) Program example

* When the driving contact is the continuous execution type, the current value of the counter is reset to "0"
  at each scan while X010 remains ON.

• Write the following program to "turn OFF the contact and reset the current value of a high speed counter".
1) Program example

* When the driving contact is the continuous execution type, the current value of the counter is reset to "0"
  and the counter reset status is cleared at each scan while X010 remains ON.

Because X010 turns ON,

"FNC12 DMOV" is executed.

The current value of C235 is

reset to "0".

Counter is reset

(part  A  in above

program).

Counter reset instruction is

(part  B  in above program).

Because the reset instruction

is deactivated, C235 executes

counting.
