can use the Get Date/Time in
Seconds.vi in our while loop with your AI code so that you can read a
sample and read the time. You can than log the voltage value and the
timestamp to your file.

Hello,
More than likely you will need to put an equation in your application.
Here is a simple example of how the application would flow:
1. Take a current measurement from the Omega using the FP-AI-110.
2. Use an equation to convert the current to units that are
meaningful.
3. Use another equ
forward to hearing from you. Simply reply to this posting.

unistall all hardware drivers on the machine. Then
try to reinstall.
If you are still unable to get the new driver installed. Just reply
to this post and I will recommend some more advanced procedures for
solving this problem.

your hardware problem solved, I can help you with any LabVIEW
questions you may have. Also, if you have any questions about our
Data Acquisition boards, I will be more than willing to answer any

this case it that you are able to find a continuous
section of memory that can accommodate the buffer.
Let me know if you need additional assistance with this issue. The
example programs should be a great reference.

uld sample channels one, three, and five. You can
also use a colon to sample a sequence of channels for example: 4:6
would sample channels four, five, and six. This makes it easy for you
to choose the channels that you would like to sample without having to
make any modifications to your code.

execute immediately after DIO
Write. In your current application it is possible for execution to be
stuck in one loop and rarely execute the code in the other. You may
also be able to place delays in both loops, but combining them both
into single loop would be the best.

You may want to try running the SCXI Strain Null.vi locally on the
machine itself rather than through RDA. This will allow us to
determine if the problem is local to the PXI-8146 or if it is being
caused by a RDA Server communication breakdown.

would ensure that both measurements had equal time.
The easiest thing to try is to decrease the scans to read in the Cont
Handshake input and insert a delay in
the while loop.
Let me know if you are successful.

. If the server machine is running Windows XP. You could just use
the Remote Desktop Connection to logon to your server machine
remotely. This would simplify things since you could just have one VI
that would do everything on the server machine.

you are programming this in LabVIEW, you will need to
have 4 VIs for configuring each port and 4 VIs in your loop for
reading each port. You can also do this in DAQmx if you have LabVIEW
7.0 or other DAQmx supported software.
