I try to analyze 7-10 images/sec during acquisition. It works with
LabVIEW 7, but I'm wondering how reliable it is.
I have a pretty simple application. A photoelectric sensor detects an
object and triggers the image acquisition. The image of this object is
then processed (a few morphological functions and particle analysis)
and results are displayed in a table before a new image is acquired.
The application also
I'd like to trigger the exposure start on the falling edge of an
external trigger signal. I use IMAQ 1394 Configure Trigger VI, but
nothing happens when I change the polarity (true or false). Is it
possible at all to control the camera via LabVIEW? Or do I have to use
the Trigger_Mode control regis
Thank you very much. Seems like my camera doesn't have a delay
function. I'm going to try an external timer.
Thanks again
Bernd
The Keyence sensor I use detects the object and triggers the image
acquisition (camera and strobe light). I'm using the IMAQ 1394
Configure Trigger.vi. The object, a small droplet, is enclosed in the
sensor at the time it is detected. So I need a delay to be able to
take pictures of this droplet af
Hello everyone, how do I change the header of the Write LabVIEW
measurement file VI? For example I want "PN, Lot#, Station ID" instead
of "Writer_Version, Reader_Version, Separator" and only "Std Dev"
instead of "Collected (Std Dev)". Thank you!
Hey Joe, thanks for your answer. Unfortunately I'm not able to find
that VI anywhere. If you could help me find it, that would be great. I
wire it then to the converted "Write LVM" VI, right?
Bernd
Hello Bob, thank you for your help. I just enter a maximum number of
samples, which is higher than my total number of samples will ever be
and then I have what I need.
Something else: can I protect my LabVIEW application with a password
as read only so it will not be changed accidentally during usa
Sorry to bother you with that last question. That was too easy.

I have a series of values one at a time and would like to calculate
the average, SD and CV of these values. I use the "Statistics Express
VI", but I'm not able to configure it so that previous data is
included in the calculation and the calculation is updated after every
incoming data point. Actual
Yeah, never mind, I got it. Thanks anyway...
I have two elements in the 1-D array and use Index Array and wire the
first index(row) and index(col) to a constant 0 and the second to a
constant 1. The first element output gives me the first element, but
the second element output returns 0 instead of the second element.
Bernd
Yes it solved the problem. I have another question if you don't mind.
How do I split a 1-D array into its elements to further work with
those elements separately?
So a case structure in a while loop. That works, thanks a lot Joe.
Thank you Enrique, that works good. Just that I need to know the count
with every consecutive, incoming value, not after the loop is
finished. So a count in real time.

After converting boolean true/false to (0,1) I'd like to count the
number of ones during data acquisition or if better the number of
trues before the conversion. Everything I tried accepted a different
type of data (string or waveform instead of word)
Hello, I try to count how often a true/false indicator is true. I'm
using a "(U16) count: the number of TTL rising edges counted" after
it, but with every incoming value the counter sets to 0. Therefore I
always have 0 or 1 on the front panel instead of adding the new true
to the previous ones. Tha
Hey Joe, that was helpful. I just had to connect both pass/fail to one
"Array Max & Min", because I wanted to know if ONE value is below or
above min max. Your VI chooses the lowest and highest from a cluster
of values and compares the lowest with min and the highest with max. I
just started with L
After visually analyzing a particle i.e. its area I need to decide if
the particle passes or fails the inspections. How do I create a pass
fail criteria after "Particle Analysis" in LabView? Thanks
