Connecting to FieldPoint devices

[rlands@my-deja.com]

Attempting to use Labview v5.1 to monitor
Fieldpoint devices FP-AI-1000(1) and FP-AI-111(4).
Using FieldPoint Explorer we are able to see the
test signal on Channel 0 through the Serial Port.
In Labview VI for the the devices were created. I
attempted to set up a graph to monitor the device
using the FP_open.vi connected to the
FP_create_tag.vi connect to a FP_read.vi connected
to a chart both inside a while loop. I used the
FP_close.vi and error.vi to close out the program.
The error I get when I run the program is 32812:
"Specified tag was not found: FP Create Tag.vi"
When I checked each subvi an error 32804 was
generated ate the create tag.vi "An invalid
IAHandle was specified: FP create TRag.vi" I ran
the config.vi and
it returned the information
needed for the create tag.vi

What are we missing?

Thank You

I often get that error if field point explorer is running at the same time,
or if there is another vi running using the same resource.

BTW, it is also very case sensitive...

Sorry - yes I was thinking about another problem - yes re check your strings
used for resource, device, and item names with those that appear in the
field point explorer.

And, above all, be sure that filename.yak does exist and is not being used by
antoher application (e.g. Fielpoint explorer) ciao Giovanni Moschioni

The error code of 32812 is usually returned in one of two situations. In certain
versions of FieldPoint Explorer (2.0.1 or earlier), 32812 could be returned from FP
Open if the addressed devices were serial modules and the serial port could not
opened (in 2.0.2 and higher, this is changed to 32830 "Unable to Bind to Comm
Port". More commonly, the 32812 code is returned from FP Create Tag due to the
fact that the item specifed by the string inputs (Comm Resource, Device Name and Item Name) do not match the names in the IAK file. The strings must be exact
matches and are both case and space sensitive."
