I have posted this error already under different name, but have got no response.
Here is the previous post:
I have some project for cRIO-9072 control. It
was designed as closed loop system to keep the vibrations of the shaker
constant by measuring acceleration by NI9233 and adjusting amplitude of
signal fed to shaker amplifier from NI9263.
To monitor and change setiings of this system there is a remote PC in a control room(about 40meters away).
When we first tried to start tis system in a plant
using Cat5 or Cat6 ethernet cables it did not work at all as it looks
like there is a lot of noise around. Whatever cables where used
(shileded, double shielded etc) they did not work. After that optical
cable was installed and some adaptor from optical to wired Ethernet.
After that it started to work OK but....
On the same place we
have some Vision device (Gig Ethernet camera that measures something)
the measurement from this camera are done on the same PC used for
RealTime interface. We had obviously to install same optical fiber
cable for this camera and adaptors Wired Ethernet to Optical Ethernet.
We are using 2 different Ethernet adaptors for Optical system and Real
Time system. In general ssystem works but it appears that Optical
System does not have very good connection, so picture sometime is
distorted. You can take a look on attached screenshot(on a right there
is an Ethernet adaptor statistics for the camera network card). As you
can see there is a lot of errors. We will try to investigate where this
errors are comeing from but for some time we could work withsome losses
from Optical device.
The thing that bothers me that the program
that is used as an interface between PC and Real-Time module stoppes to
work approximately every half a day. The real time system still
continues to wor. MAX shows that device is connected and running, but I
have to reboot RealTime device from MAX and restart my interface
program on PC. After that it works OK for some time.
I have included screenshot of error. As you can see there are some errors on it. Some of them are connected with NI.
One of the questions could Vision application connection error interfere with RealTime appplication?
What are the thoughts about avoiding theproblem of RealTime application.
Any comments are welcome.
Sorry for such long explanation....
