 Hi,

hi vaibhav,

The project attached in my post there is only one vi called  Ladder.vi. Now I want this vi mde into executable. The logic is written in Ladder file that is Test Ladder.lvlad. In ladder I set and resat booleans and writevariable of that. Now in my vi file I only read that variables. For this condition I want to build executable for that VI so that ladder also run in backend so  that I get variable status in my VI. Guide me in doing this. Is it possible to build executable containing LabVIEW Ladder file. 

Thanks..

Regards

Hi Malhar,

The following sentence is from the LabVIEW Help topic for creating Ladder diagrams:

You can build a .exe or .rtexe application from a LabVIEW VI that includes a ladder diagram as a subVI.

In your sample app that you attached, the ladder diagram is being called at the top level, and not as a subVI.  If you call the ladder as a subVI (maybe by adding it to the diagram of Ladder.vi, along with some logic that will cause it to stop when the stop button in Ladder.vi is pressed), you should be able to build and use an executable, but the ladder UI will not be available when calling the ladder from a built EXE.

Also, for the future, I recommend posting questions about ladder diagrams to the Ladder Diagram Editor thread in the NI Labs discussion forum.

When I saw this post, I got rather excited, as I had to program a PLC in Ladder Logic, and said "Gee, I wish I could use LabVIEW".  So I followed the Ladder threads, only to find that the LabVIEW Ladder Diagram Editor was developed for LabVIEW 8.6, and then was dropped by NI and never made it to LabVIEW 8.6.1 (and the downloads were removed).  Oh, well ...
