Counters

Routing Counter

n

Z Signal to an Output Terminal

You can route Counter

n

Z out to any PFI terminal.

Counter

n

Up_Down Signal

Counter

n

Up_Down is another name for the Counter

n

B signal.

Counter

n

HW Arm Signal

The Counter

n

HW Arm signal enables a counter to begin an input or output function.

To begin any counter input or output function, you must first enable, or arm, the counter. In some
applications, such as a buffered edge count, the counter begins counting when it is armed. In
other applications, such as single pulse-width measurement, the counter begins waiting for the
Gate signal when it is armed. Counter output operations can use the arm signal in addition to a
start trigger.

Software can arm a counter or configure counters to be armed on a hardware signal. Software
calls this hardware signal the Arm Start Trigger. Internally, software routes the Arm Start Trigger
to the Counter

n

HW Arm input of the counter.

Routing Signals to Counter

n

HW Arm Input

Any of the following signals can be routed to the Counter

n

HW Arm input:

•

Any PFI terminal

•

AI Reference Trigger

•

AI Start Trigger

•

Analog Comparison Event

•

Change Detection Event

A counter’s Internal Output can be routed to a different counter’s HW Arm.

Some of these options may not be available in some driver software. Refer to the

Device Routing

in MAX

topic in the

NI-DAQmx Help

or the

LabVIEW Help

for more information about available

routing options.

Counter

n

Sample Clock Signal

Use the Counter

n

Sample Clock (Ctr

n

SampleClock) signal to perform sample clocked

acquisitions and generations.

You can specify an internal or external source for Counter

n

Sample Clock. You also can specify

whether the measurement sample begins on the rising edge or falling edge of Counter

n

Sample

Clock.

If the cDAQ controller receives a Counter

n

Sample Clock when the FIFO is full, it reports an

overflow error to the host software.
