Basic functions RIO C24-10
The following basic functions are active after the power supply has
been switched on:
·
Actual counter values = 0
·
Counter start values = 0
·
4 16 bit counters (2 32 bit counters can be set in control data word
5)
·
Interference suppression for counting frequencies up to 20 kHz
·
Every counter counts the input signals as long as the enable
signal (gate) is set.
·
Counting method: Up to the respective minimum/maximum value,
no reset when the maximum number is reached
Data configuration 4 counters 16 bit
