datasocket

[enzo78]

Hi

I want read some shared variable (boolean tipe) with Datasocket, see my VI attached...

If I run the VI with Highlight Execution it works for  the most part of the shared variable that is reading and give just sometime the error at the block "convert variant to data" ,

if I run in normaly mode it give me always the error.

I developed this block how many example explain, what I wrong?

Thanks

Hi enzo78,

are you sure you receive boolean data? There is an OpenG vi, with which you can check the type.

Hope it helps.

Where can I find this OpenG?

As Mike mentioned, you want the lvdata library.  This is the specific VI that you want:

Hi

first of all, thanks for the help.

I haven`t in my library that block, I can`t find it, but I put an indicator on that variant and it give me this output:

FALSE

5 Attribute(s):
   'OdcFlags' -> 7
   'Quality' -> 0
   'Status' -> 0
   'TimeHigh' -> 29938356
   'TimeLow' -> 2686954624

What means? Can it be helpfull?

Thanks

Hi enzo78,

i think it is a cluster, so that´s why you get the error, you can´t convert cluster to boolean.

You need to install OpenG in order to find this VI:
