Well, that's true that Real-Time does not support Write JPEG file (this is the first problem). I'm using now Write BMP file insteed. The second problem, verified also in my practice, is that the Front Panel does not exist too on Compact FieldPoint.
My aim is to develop web-interface to deal with the
Compact FieldPoint from any computer. That is true that it has its own built-in
Web-Server, but it doesn't have a script-executive environement. My idea was to create a
custom "web" server running in parallel with the principal Web-Server to execute VI scripts.
For that purpose I used
TCP Listen -> TCP Read -> TCP Write runing on the port 82. I can send from any browser the request
http://<IP address>/<script.vi>?<params> and my custom server parses the request and executes the
<script.vi>. Then to avoid the problems with HTTP protocol I write the redirecting request to the port 82 like
<meta http-equiv="Refresh" content="0; URL=<result_page.html">. So, It works.
The
result_page.html must represent the acquired data from the Compact FieldPoint channels. So, I execute a requested script to show the specified data into Graph waveform and then to take a snapshot and to save to the Compact FieldPoint. Then the result_page.html contains the link to the saved snapshot picture.
Once executing the requested VI script, the Invoke Node gives the
error 1003 stating that "the VI is broken etc...". I think that is because of the script attempts to take a snapshot of a panel which doesn't exist...
Maybe somebody has an idea how to
view the acquired data in browser ?
