Help, there has to be a more efficient way!

[wyked]

Hello,

I'm trying to read a cFP bank of modules into my PXI real time system.  I have everything communicating through an ethernet hub.  In my target VI I'm trying to read from the cFP using Datasocket reads with URLs "lookout://IPAddress/FP/8TC/00" for the DS Open.  I am able to read each channel individually but seeing as I have 64 channels to read I'm thinking there has to be a better way?  I've tried to read in "All" for the channel location to try and read in a whole module at a time but that doesn't seem to work.  I have to be missing some easier/efficient way to do this?  Any help is appreciated.

Thanks

wyked,

So the good news is that there is an easy way to read all of the channels at once. See below:

Thank you Chris, but it is my understanding that real time does not support fieldpoint sub vi's? That was the first thing I tried and when it wouldn't work, I'm not sure why as that would seem the most logical.

wyked,

I stand corrected. You're right. You can't use the Fieldpoint API on a RT PIX platform. I thought about using shared variables to bind to the all channel might work but I don't see that happening either.... so at this point it looks like you can either use a for loop and change the text for the datasocket read or create a separate datasocket read for each channel of interest.

I found a discussion forum that reinforces these findings titled How to read All FP-Channels via DataSocket?

I think this would be a great suggestion though!

Thanks again Chris,  I tried the shared variable approach too and could not bind the variable to all of the channels.  I'm concerned about putting the read in a loop to consecutively read all the channels as this would take awhile reading 64 channels and I could easily miss an alarm event while I was reading the rest of the channels.  So basically it's sounding like I'm stuck with what I have done already?

wyked,

One last ray of hope..... maybe. Create a new shared variable and bind to source. Select Network Items and navigate to your computer. Then expand system>>Fieldpoint>>Max Data Neighborhood and navigate to your module. You should see an "all" there.
