Great thanks for the information. I now have it working. Looks very promising. One thing to note for other users, if you use the "Abort Execution" button in the toolbar, then not all processes are destroyed and the second time you try to run it, you will have errors. You should use the "Stop" button on the GUI interface. I am not sure if there is an easy way to prevent this. (I have removed the "about execution" button from the toolbar"), but it would be nice if there was a better way to close the Vi's running in the background. Thoughts? On a similar note, can you recommend any web hosting sites (free) that will allow deployment of the generated web interfaces? Cheers Ian

Hi hooovahh, Thanks for the update. I am having trouble running the newer version, as the "WebService" option in the Project is now missing. therefore I am unsure how to start the service. Please can you provide instructions? Thanks for your hard work. Cheers Ian

smithd, ThomasGutzler. Thanks for your help. I now have it working. Excellent.

Excellent idea. However, I am having issues getting the demo to work. (I have not used the webserver before so it might be user error). I am doing the following: 1) Open Labview project "FPPublisher.lvproj" 2) Enable Webserver. a) Select "Tools->Options...->Web Server" b) Select "Configure Web Application Server". A web page will open. 3) Open and Run "FPPublisher.lvproj->My Computer->To Publish->Main.vi" 4) Check Web Server Application has been published a) In "Configure Web Application Server->Web Services Management" In my case nothing shows in this box, which I think is causing the problem. 5) Get server webpage a) In project explorer, right click "FPPublisher.lvproj->My Computer->WebService->Public Content->Main.html->Show Public Content URL" b) Select either "local debugging" or "Application" and then "Copy URL". 6) View in webrowser. a) Paste URL into Chrome If I use the "local debugging" url I get: or the application url, I get: Any suggestions/ideas of what I am doing wrong? Appreciate your help Ian

Phillip, thanks for the advice. I tried updating the drivers as you suggested, but still with no luck.

Hi, A quick update in case anybody else is interested. I purchased the Maplin 4 Port USB Gigabit Network Server (http://www.maplin.co...k-server-521590) because it was low cost and easily accessible. I installed the software and connected it to my LAN. I started the server on my local computer and the Ethernet to USB hub was instantly recognized. I then connected the NI-USB-6008 to the device. The NI-USB-6008 was detected and tried to download the driver software but failed. I then connected the NI-USB-6008 directly to the computer, the driver installed correctly. I then connected the NI-USB-6008 back to the USB Network server. It appeared in Device Manager under "Data Acquisition Devices", but failed to start giving the message "This device cannot start (Code 10) in Device manager. I have tried updating the firmware but this doesn't help. Other USB devices seem to work correctly. After a bit more research I found the following post: http://forums.ni.com/t5/LabVIEW/Has-anyone-used-a-USB-device-server-with-a-DAQmx-or-NI-VISA-USB/td-p/2152768 The down side is that it is >10 time the price.

Hi, I would like to control some of my USB devices over ethernet (e.g. NI USB-6008, http://sine.ni.com/nips/cds/view/p/lang/en/nid/201986) Has anybody tried using or can recommend any Network attached USB Hubs? The following are examples I have found on the internet: http://www.digi.com/products/usb/anywhereusb#models http://www.bb-elec.com/Products/USB-Connectivity/USB-Over-Ethernet/USB-Over-Ethernet.aspx http://www.maplin.co.uk/4-port-usb-gigabit-network-server-521590 Do you know if they work with Labview? Thanks for your help

Thank you to everyone, some very useful advice.

Hi, I need to control up to 32 serial port devices (RS232) using Labview. Can any body recommend a product that will do this? I have been looking at Terminal Servers (e.g. http://www.perle.com/products/Terminal-Server.shtml) Does anybody know if I can use this device with Labview to access each RS232 device.(NB: I can currently access each device using TeraTerm). The recommended retail price for a 16port unit is £800. Can anybody suggest a cheaper solution? Thanks in advance. Cheers Ian

Hi, You can try looking at the following for a list of online hosting facilities: http://en.wikipedia.org/wiki/Comparison_of_open_source_software_hosting_facilities Bitbucket offers a free service: https://bitbucket.org/?page=overview From reading the forums, SVN is popular. Assembla is a free limited (1Gb) hosting service: https://www.assembla.com/home I found Assembla quite good, and offers a few guides to get you started.

I have also just started to learn LVOOP. You might find this of particular interest with regard to implementing classes for different instruments: 1) http://zone.ni.com/devzone/cda/epd/p/id/6307 (This is a good white paper and provides examples similar to what I think you are trying to implement). 2) http://vishots.com/hardware-emulation-using-labview-classes/ 3) http://vishots.com/005-visv-labview-class-factory-pattern/ Also the following provide additional resource: 1) http://zone.ni.com/wv/app/doc/p/id/wv-1766 2) http://zone.ni.com/wv/app/doc/p/id/wv-2003 3) https://decibel.ni.com/content/docs/DOC-15014 4) http://zone.ni.com/wv/app/doc/p/id/wv-2820/nextonly/y 1 and 2 provide a very good overview if you are just getting started with LVOOP, 3 and 4 start getting quite involved. I hope this helps Ian

I have done a quick web search for LVOOP 101, but can't find anything relevant. Do you have a web address? Cheers Ian

There are some excellent tutorials/webcasts on NI website. Start here: http://zone.ni.com/devzone/cda/tut/p/id/7466 http://search.ni.com/nisearch/app/main/p/ap/tech/lang/en/pg/1/sn/catnav:mm,ssnav:dzn/ http://zone.ni.com/dzhp/app/main Instrument drivers can be found on NI website: http://search.ni.com/nisearch/app/main/p/ap/tech/lang/en/pg/1/sn/catnav:id/ A state machine is an excellent place to start: e.g. http://lavag.org/topic/14666-100-new-to-labview-need-to-learn-how-to-talk-to-jds-optical-attenuaters-and-optical-power-meters-any-help-on-how-i-should-start/ What is the model of the JDSU optical attenuator?
