Description
Performs high−speed counter control according to the control code specified in “S”.
This instruction is used to perform the following operations when using a high−speed counter:
<Function>
1) Performing a software reset
2) Disabling the count
3) Temporarily disables reset input setting using external inputs
4) Clearing control executed with high−speed counter and pulse output instructions F166 or F167.
Once written, a control code is retained until the next write operation.
Precautions during programming
Hardware resets can only be disabled if a reset input is used.
