  1. I've got some weird stuff going on with a cRIO project I'm working on wanted to get some opinions on it. The basic architecture is a set of classes that do some process. That process registers with a server. The internal data of the process is held in a DVR and the server get's access to that DVR. Clients use TCP to ask the server to do something, the server makes a call against the classes DVR and returns a response to the client. To simplify the issues I'm seeing I created a class that internally just increments an integer every 500ms. The client asks the server what's the current count
  2. Hi all, So I'm working on making a certain vi a remote panel. However this vi is quite complex with a lot of property nodes events which makes remote panel connection can be a bit unreliable cross-site because of the amount of data being transferred. What i'm trying to do to solve this is use a secondary vi that grabs an image of the first vi's front panel at a given frequency so that any changes are seen with out having to send too much data back and forth between the server and client. Basically all we should see is the change in pixels. When a user clicks on the image on this seco
  3. I'm having some issues with a LabVIEW driver I'm writing for a Mensor CPC 6000 pressure controller. Issue I open the TCP Connection using the LV "TCP Open Connection" VI, and can then successfully read various values from the Mensor, such as "id", "gasDensity", etc., using the "TCP Write" and "TCP Read" VIs wired with the connectionID refnum. I save the connectionID in a shift register and want to use this connectionID to write and read values the next time the VI is executed, however as soon as I perform a "statusUpdate", "TCP Write" returns Error Code 1. Tests already p
  4. Hi, I am currently developing a scope that displays live data from a test rig. The scope is accessible via remote panels. Tests normally run for many hours at a time, when monitoring the scope after several hours of running I notice that the data on the chart displayed via the remote panel is not in sync with what can be seen on the actual 'server' vi. The delay also seems to be getting bigger as time goes on. I also display the current data points in an indicator; however these seem to be in sync and 'current'. The scope is part of a built application and I am using labVIEW 2012 f3
  5. LabSocket enables LabVIEW applications to be easily accessed using a web browser, without the need for browser plug-ins or run-time engine on the client. The latest release of LabSocket includes support for Waveform Graphs and Charts, XY Graphs and MultiColumn ListBoxes. An option to integrate LabSocket with the Moodle CMS is available as well. A detailed User Guide and downloadable demo of this release are at: http://labsocket.com/userguide_demo.html. Below is a screenshot of a test VI (left) and its representation in a browser (right). LabSocket-RT, a special version of LabSocket
  6. Hi everybody, I am wondering whether or not it is possible to call the functions of a dynamic library over a LAN connection, without needing to control a VI on the server using the LV remote server (my server is Win7 embedded on an SSD, so not much resources to waste running the RTE). Does the "Shared library file is not on the local machine" checkbox allow that when using the Import Shared Library wizard? Is there any easier solution than implementing a protocol over a TCP connection to access my DLL's functions? Thanks in advance, Sylvain F.
