New Fieldpoint VI LabVIEW 7.0

[Golzio]

Hi all,
the new Fieldpoint VI introduced with new LabVIEW 7.0 are very useful because we don't need to place the following:
FP Open VI
FP Create Tag VI
FP Close VI

I have a little doubt!! Before LabVIEW 7.0 in my apps I opened Fieldpoint session, then I created all tags and then I executed all my read and write I/O functions. At the end of my apps I close the FP session. My first impression was not useful (lots of wires!!) but efficient.
With new VI is the low level source code that manage this thinghs for us??
I have a large app that I converted with new VI's and now I'm going to compared with the old code with new LabVIEW. If there is someone with this kind of experience I will be very happy to discuss about this aspect.

Regard

Hello Alessio,

The new FP Read and FP Write make reading and writing FP Items simple. The FP IO Point contains all the configuration information of the module and channel from which you would like to read or write. Therefore, you can just browse the channel of a module that you would like to use and then either use FP Read or FP Write. The opening and closing is handled automatically by the driver software, all you have to do is supply the data and call the FP Read or Write with an FP IO Point connected.

Please let me know if you have any other concerns. If you are worried about performance, I encourage you to setup some simple tests to compare the new method to the older method where you had to create a tag and close.

Regards,
Bill B
