The driver executes the according action when
counting value arrives at preset value of F7.32.

This function code defines counting reset value and
detection value of counter. When the counting value
arrives at the preset value of F7.32, the corresponding
multi-function output terminal will send out valid
signal and the counter will be cleared to zero.
When the counting value reaches the preset value of
F7.33, the corresponding output terminal (output
signal of counter detection) sends out valid signal. If
the counting continues and exceeds the preset value
of F7.32, this output signal will be revoked when the
counter is cleared.
As showed in the following figure: the
programmable relay output is set as reset signal
output, open collector output Y1 is set as counter
detection output, F7.32 is set as 8, F7.33 is set as 5.
When the detection value is 5, Y1 output valid signal
and maintain it; when detection value arriving at reset
value 8, the relay output valid signal of one cycle
impulse and the counter is cleared, meanwhile, Y1 and
relay will revoke output signal.
