LV QuickSheet

Save time with the LV Quicksheet.

You want to solve a problem for which you need several LV modules. Then the new LV QuickSheet allows you to manage all module combinations created in a project using an independent input mask.

This allows a complex task to be processed conveniently using a single input mask.

Latest issue 2019-10-15

After a Windows patch the LV programs do not work anymore on some computers.

There is a workaround at the moment, but it turns off the online help:

In the registry under

HKEY_CURRENT_USER\Software\Lauterbach Verfahrenstechnik\LvStart

set a new string value „LvOfflineHelp“ snd specify the value „-1“.
