Need to run a "fieldpoint clear" before fieldpoint modules respond swiftly

[sean T M]

Hi,

I'm running Labview 7.0 on Windows 2000.  We are using fieldpoint cFP-2000 modules.  Before running our main Labview application we must run a simple "field point clear" application that allows the user to manually toggle an output on a fieldpoint module.  If we don't run this, the communications with the fieldpoint module in the main app. is extremely slow (taking many seconds to respond).  Why would this be?

Thanks,

Sean

Sean,

This might help.  Create an empty file named fpremote.ini and put it in the directory "ni-rt/system" of your target.

Wayne, thanks for the suggestion but I don't have an ni-rt directory anywhere on my host system (the PC that runs the labview program).

cFP is the target.  Look there.

How do you actually put a file on a cFP module?  I wasn't aware they have a filesystem at all, have never seen it exposed by any of the software.

[Wayne.C]

You said you had a cFP-2000 which is a controller module which has a file system.  Maybe you should better describe the hardware you actually have.

Yes I do have a number of cFP-2000s, how do you access the filesystem on them?

[Wayne.C]

cFP has a built in FTP server.  Client built into Internet Explorer works well for this connection.

Thanks, I was able to FTP the files there but it hasn't made any difference.

As soon as my Labview program has to interact with a fieldpoint module runs extremely slowly (e.g. only one loop iteration per minute or so).

Any other ideas as to what could be going wrong?

Thanks,

Sean

Sean,

Serial or ethernet connection to cFP-2000?  What specific method to read/write the I/O?  Datasocket, logos etc.  I found this post about datasocket and performance.  http://forums.ni.com/ni/board/message?board.id=170&message.id=70610
