Indicator won't bind to a Single Process Shared Variable

[Peter_B]

Hi there,

When I attempt to bind a single process shared variable to an indicator, LabVIEW gives me the following error:

I have attached a project with the example code.  It currently works OK because I have set the SV to be Network Published. 

To cause the error, simply edit the properties of the SV from its library in the Project Explorer, changing the type from NP to SP (see screenshot below).

The reason I want to use the SV as a single process is to reduce the overhead as it isn't being shared over a network.  Here is the help file text:

.

"Variable Type—Specifies the scope of the shared variable. Select Network-Published from the pull-down menu if you want to share the shared variable data across a network. Select Single-Process from the pull-down menu if you want to share the shared variable data among VIs on the local computer."

The Double Numeric indicator on the top level vi is already bound to the SV as follows

So... why can't I bind my SPSV to an indicator ?

Hi Peter_B,

The front panel data binding is only applicable with networked shared variable.

Check out this link about shared variable.You will find answer to your question in "Front Panel Data Binding" section.

Thanks for pointing that out Gaurav. To me it seems like an unnecessary limitation. I wonder why NI did it that way. Rgds
