Counter number
•
The output value will be changed according to the output condition (on-preset value, off-preset value settings) if the count
value of the specified counter number is cleared and coincidence output is possible.
Notes
•
If a value other than H01 to H04 is specified for the counter number, DER will be set to "1" and no processing will be
performed.
•
If the specified counter number is set to a function other than a corresponding external I/O counter (single-phase counter,
two-phase counter), DER will be set to "1" and no processing will be performed.
•
Since Counter 4 is invalid when a 10-point CPU is used, if Counter 4 is specified, DER will be set to "1" and no processing
will be performed.
•
If the specified counter number is unable to make an output (PI/O function setting result by R7F5), DER will be set to "1"
and no processing will be performed.
•
This instruction is used only to clear the count value. Other counter settings will not be changed and it will not affect the
count operation.
