Hello, I 'm interested in Wireless Filedpoint. Now I have Fp 2000 module AI,CTR,TC module connect to sensor.They are working propery But now I would like to Fp 2000 standalone(I will leave it in my farm ) and send data of sensor to my pc at my office. Someone Tell me about GSM/GPRS modem and I can control it via serial port on Fp 2000 ,send excel file it OK.........But now I want to view HTML file which I build from LABVIEW(Web Publishin) by use GSM/GPRS modem

It possible? Please guide me........

Hello,

I would like to understand where you are having trouble.  Are you having trouble with:

a). configuring/setting up/launching things on your fieldpoint module?

b). finding a GSM/GPRS modem that can be controlled via a serial port?

c). using the web publishing tool in LabVIEW to publish the front panel of a VI?

d). something else?

This should help decipher exactly where the problem is. 

If you're having trouble with a), then this will be a question for fieldpoint - just post that this is indeed the case here with a more detailed description so someone with fieldpoint expertise can assist you.

If you're having trouble with b), then you'll probably want to search the web for a GSM/GPRS modem that can be controlled via a serial port.

If you're having trouble with c), then the following information will be helpful:

NOTE: Copy the complete links below if necessary to view noted URLs.

The web publishing tool allows you to publish the front panel of any VI to the web using LabVIEW's built in web server.  Then, based on IP address you can either allow people to view and control the VI remotely, or simply view the VI, or deny access altogether; these are configuration options you have for the built in web server.  You can also configure which VIs are even viewable (ie. exported for view).  For a web published VI, LabVIEW simply posts the current image to the web and then allows access to the VI per your configuration.

The basic steps are:

1. Enable and configure the LabVIEW Web Server; see Tools -> Options... in LabVIEW, and then "Web Server:" drop down category selections in the window that pops up.
2. Publish the VI of your choice using the machine on which the VI will run; see Tools -> Web Publishing Tool... in LabVIEW, and the window that pops up will allow you to customize the web page.  You can further customize the web page by modifying the html document directly.  When you click Save to Disk an html file with the name of your choosing will be written to
C:\Program Files\National Instruments\LabVIEW 7.1\www

All you have to do then is record the URL that is assigned to it and use it in your favorite browser; the form of the URL in general is http://yourIPaddress/nameOfYourVI.htm

Note that when the URL is constructed, every space in the name of your VI will be replaced with %20.  Thus, to avoid strange looking URLs, simply name the VIs you wish to web publish without spaces.

WEB PUBLISHING WEB DOCUMENTS/INFORMATION:

1. For a general overview of features (organized by distribution type: developer suite, professional, full, base) including web publishing and internet features (see the Connectivity Tools Section of the table of features, there is a link at the top of the page to jump there as well - notice that web publishing is available down to the base package, but remote control of web applications requires at least the full package) , the best place to look is:

https://www.ni.com/en/shop/labview/select-edition.html

2. For more specific information about web based applications with LabVIEW, the following are good places to start:  (Note: remote front panel often refers to viewing and controlling the front panels of VIs over the network, from within the LabVIEW environment, where as web publishing often refers to viewing and controlling front panels embedded in an html document).

A). Basic Information:
- Use the LabVIEW Web Server to publish images of front panels on the Web. By default, after you enable the Web Server all VIs are visible to all Web browsers. However, you can control browser access to the published front panels and configure which VIs are visible on the Web. To display front panels on the Web, the VIs must be in memory on your computer.
- Use the Web Publishing Tool to create an HTML document and embed static or animated images of the front panel. You also can embed images of the front panel in an existing HTML document.
- The front panel of the VI you want to publish might be large. It takes the Web Server longer to create a large image, which can slow the execution of the VI. Also, a large image takes a significant amount of time to transmit to the browser, especially over a slow modem connection. Therefore, make sure the front panels of VIs you want to publish are a reasonable size.

B). Title: Publishing Your Data Over the Web

- Can I Use Remote Panels to Publish the Front Panel of a Sub-VI in My LabVIEW Executable? 
- Can I Access a Remote Front Panel Running on a Windows Machine with Mac OS X?

If you're having trouble with d), please explain in further detail.

I hope this helps decipher the problem further!

Hello JLS, Now I have GSM/GGPRS modem (WAVECOM) and I can control it by serial port on FP 2000 already(I use it to send Excel file to my PC),

But my problem is I can not view HTML file which I build from Web Pubilishing Tool in LabVIEW 7.0.

I know FP 2000 have HTTP SERVER on it and we can access by UTP(RJ-45) cable............Can I access it to view HTML by GSM/GPRS modem?

Hi woot-

The LabVIEW web server that runs on the FP-2000 can only interface to publish directly via the ethernet port.  This interface requires that the page be addressed externally via the IP address or hostname of the controller.  So, there is no built-in mechanism to publish to a modem that does not interface with the ethernet port or that does not have the ability to publish http information directly.  If you could find some driver or software to repeat all outgoing/incoming UDP traffic from the module this may work, but it would be extremely difficult.  A better suggestion might be to use a wireless router or access point to interface with your modem so that the native communication protocol could be used.

Hopefully this helps-
