cFP and shared variable binding

[Michael_Wise]

I think I'm starting to lose my mind, but let me know if this is not possible.

I have a cFP system setup with scaling on the cFP channels.  I want to bind those to shared variables with the SVE running on the cFP controller.

When I access the values using read cFP I get the scaled value.  However, when I use the shared variable which is bound to the network address of the cFP IO channel, the scaling goes away and I see the raw value from the cFP hardware.

Is there not a way to have the shared variable use the scaled value?

Thanks,

Michael

Anyone have anything on this issue?

Don't bind the shared variable to the cFP I/O.  Modify the vi on the cFP to write the scaled value to a shared network variable that a remote vi can access.

Thats essentially what I've done.  The SVE is being hosted on the cFP.  I'm using a feedbackRAW variable bound to the cfp I/O, applying scaling, and then writing to a feedback variable.  Obviously, if I had DSC I could just apply scaling to the shared variable.  I just don't understand why the scaling on the cFP channel doesn't show up when you bind a variable to that I/O.

I'm sure it is directly related to how LV handles scaling cFP I/O.  Can only speculate that when the shared variable engine reads the cFP I/O, it does not know about the scaling that is in place and thus does nothing about it.
