Muti-channel read/write through FP data socket posible?

[Fedor]

Hello,

I'm trying to talk to cFP-1808 module from desktop PC real-time host over Ethernet. I did not find any Fieldpoint driver for desktop RT so I'm forced to use data sockets to communicate with cFP-1808. It seems that one can only read or write to one FP data channel per socket. With typical latency of tens of milliseconds per such read/write and couple of hundreds channels present, I'm looking at SECONDS per cycle time, which is really slow.

Is there any workaround for this problem?

Instead of putting the channel name after the final slash in the datasocket address, try  \All.  That should return an array of all the addresses.

At least that is what I remember from when I had to do this.  I don't have access to that system right now to confirm the syntax.

You can also read and write to channels in LabVIEW.  First you have to configure your 1808 in MAX and save the IAK file.  You then load the IAK file in LabVIEW by selecting browse in the FieldPoint IO Point In (constant or control).

In the FieldPoint Device Selection Dialog Windows select the View Configurations Tab.

In this tab navigate to your IAK file and name it in the text box next to where the full file path is displayed.

In the Browse FieldPoint Tab of the same window you should now be able to see all of your FieldPoint modules and channels.

Mark,

Thanks for suggestion, but as I've mentioned I'm trying to control cFP module from a computer running ETS RT and it seems that regular fieldpoint Labview VIs such as "FP read.vi" can not be used on the  ETS RT target. I don't even see an option to install fieldpoint driver software on the ETS RT target.
