Parameter: “Pulse detection on”
The type of input signal is defined in this parameter. It can be set whether
the contact is a normally open contact or a normally closed contact.
Parameter: “Data width of counter”
The data type of the counter (absolute counter and differential counter)
is defined in this parameter. The data type specifies the counting range for
the counter.
The type of the objects “Telegr. counter value …” and “Differential counter …”
is adapted to the data width.
Parameter: “Counter starts at …”
The starting value of the absolute counter is defined in this parameter.
The starting value is used when there is a counter overflow in order to
calculate the new counter value.
Parameter: “Debounce time / min. operation time”
The debounce prevents unwanted multiple operation of the input e.g. by
bouncing of the contacts. Refer to section 5.1 for the exact function of this
parameter.
Parameter: “Transmit counter values after bus voltage recovery”
If this parameter has the value “yes”, the current value of the counter is sent
on the bus after bus voltage recovery (once the transmission delay has elapsed).
If the differential counter has been enabled, it is also sent on the bus.
After an extended bus voltage failure, the counter is reset to the starting
value. If the differential counter has been enabled, it is reset to zero. If no
data loss has occurred after a short bus voltage failure, the counter contents
are retained.
Parameter: “Enable additional options (…)”
If this parameter is set to “yes”, the parameter window “A-Counter” is displayed.
Additional functions are possible here.
Parameter window: “A-Counter”
Additional functions can be activated in this parameter window for the pulse
counter.
Parameter: “Divider: number of input pulses for one counter step”
It can be set via this parameter how many pulses are necessary to generate
a counting pulse. It thus functions as a divider.
Parameter: “Factor: one counter step changes counter value by”
This parameter defines how much the counter and differential counter should
be increased by in the event of a counting pulse. It thus functions as a factor.
Parameter: “Transmit counter values cyclically”
If this parameter has the value “yes”, the values of the counter and the differential
counter are sent cyclically on the bus.
