Hello,
When you launch a HMI VI assynchrounously using the "Run VI", the mechanical actions of the controls are not taken in account.
When i launch the same VI directly using the run button ... all works fine !
For example i wanted to use a "Switch until release" ... The value of the control should stay true until i release the mouse button.
in assynchronous running mode, the control doens't keep the "true" value until the mouse button is released ...
the control value automatically change to false value even if the mouse button is pressed !
It seems that there is a different behavior between ...
- A normal run
- An assynchronous run
=> The events are not handled the same way in both execution mode.
It should be nice to make the mechanical actions works in both cases ...
Or if the problem is linked to the LabView inner architecture, to explain this particular behaviour in the Labview Help.
One of my collegue gets also a problem like mine using FPGA IRQ methods calls ...
- The Wait IRQ works fine in a "Main VI" launched by the Run button.
- The same code generates an error, if the VI is launched assynchronously.
I think that the behaviour difference of the 2 run mode (Direct run or assynchronous run) should be described in detail in LabView Help ...
