Change values from a Sub-Vi

[asic]

Hi,

I use an instrument driver to communicate over RS232 with a Keithley 2000.

Do someone know how can I add a control to my Top-Frontpanel which modifies the baud rate.

My problem is, that the baud rate variable is located in a Sub-Vi.

P.S.:Perhaps, a global variable can help me???

Hi,

On your sub-VI which has the baud-rate Control, connect this Control to the connector pane making it one of the inputs. (If the baud-rate is a Constant on the diagram, you will replace it with a Control on the front-panel).

Then, in your top-VI, add a Control to the panel and wire its terminal to the baud-rate input you just created on the sub-VI. (Or, an easier option is to right-click on the baud-rate input you created and select Create Control. This will add the Control to the top-VI's front panel.)

Hope this helps.
