Unable to Edit SubVI

[harisskriss85_85]

Hello,

      I am trying to modify an existing LV Program. It has some SubVIs which can't be edited. It has no facility to use a probe or Execution Higlighting. So I am stuck unbale to visualise the data flow, neither able to add indicators to see whats happening. Please find the image for further details. Please help me out.

Best Regards

The ":2" after the file name in the title bar means that it is a clone of a reentrant VI. You can't edit the clone - only the original VI. If you press Ctrl+M while the VI isn't executing it should open the original VI which you should be able to edit.

I would imagine that also debugging is turned off on the VI which is why you can't probe/highlight execution while it is running - that's a setting in VI properties.

This was probably done because it looks like a manufacturer supplied driver VI so they probably turn off debugging to improve the performance.

Hello Mr.Sam,

          Thanks for the reply. As you mentioned I have used Ctrl+M to open the main document. But still its uneditable. I went to VI Properties, but unable to find the settings for probe.

Under Ausführen you can enable "Allow debugging" which'll give you access to the Highlight execution and Retain wire values (and also probes).
