How to change user event definition online?

[SnowForest]

Hello All,

There is a very good example ( DSC Event Structure Demo.lvproj) how to generate user events from shared variables. I have tryed to modify this example that I can change one of these variables online. We can assume that I want change e.g. \\My Computer\EventsDemoVariables\DiscreteVariable to \\My Computer\EventsDemoVariables\MYTESTVARIABLE online. Is that possible? Can someone give me a hint how to program such function.

I tested to put definition blocks inside event-while loop, but then program start to generate events constatly. I also replaced this shared variable constant to shared variable control.

Regards,

Hi SnowForest!

It is possible to edit share variables programmatically. You should get reference to variable. For more information check knowledge base "How do I configure shared variable properties with the DSC module 8.x?"

1) Use invoke node to open library (application class -> library -> open)

2) Get reference to variable you wish to modify

3) Use property node to modify your variable

4) Close references

I've done small example for you, so I hope will be helpfull

Martin
