I am using Labview Professional Development System version 8.6.1
With compact RIO CRIO-9074
I created a target VI which runs on the cRIO. In this VI, I added a PID function block from the function palette from the real-time\function blocks sub palette.
I double-clicked the PID function blocked and changed the variable scope of the setpoint to network-published.
Now, on the project explorer, I see the PID function block listed under the new target VI I created.
I open a new VI on the computer and add a new numeric control. I right-click the control and select properties. I select the data binding tab and change the selection to "Shared variable engine". For the Path, I browse to the target VI on the CRIO and select the Setpoint under the PID function block and press OK. The path shows up in the data binding tab. But the OK is not enabled.
To work around this, I can drag-and-drop the setpoint from the project explorer to the new VI. the binding is created and it works. However, if I modify the Path (by browsing or simply by typing a new path, the OK is again disabled.
With shared variables that I create manually, I do not have this same problem. If I create a variable, I can browse and select the path to the variable.
attached is the target VI and a PDF showing the promlem
