The DL-CNT1 module contains 4 counters with 24-bit range
(numerical range of each counter is 0 to 16,777,215).
The first two counters have more configuration options compared to
the second couple of counters ():
Alarm output can be set when counter value exceeds defined
value. Output logic (if active high or low) can be defined in the
counter configuration. Counting can be enabled/disabled by the external input
(gate). Gate logic (if active high or low) can be defined in the
counter configuration. Inputs of the last two counters are used as
gate inputs for first two counters. (counter 2 input works as gate
for counter 0 and counter 3 input works as gate for counter
1).
Third and fourth counters functionality is limited to simple
counting with the possibility to read and preset counter value.
Counter modes (counting enable, logical signal levels etc.) are
defined by software.
The DL-CNT2 contains one incremental counter with 32-bit
precision (counter numerical range is -2,147,483,648
to 2,147,483,647). The counter is also capable to
preset counter value and capture value according to logical inputs
and to signal alarm outputs if the counter value underflows low
limit or overflows high limit. The counter can work in three
modes:
counting of quadrature-modulated inputs counting of two up/down inputs counting of two step/direction inputs
Thorough module description can be found in the DataLab IO/USB hardware documentation. Software control and
configuration options are described in the DataLab IO/USB Active X and
Control Web driver documentation.
