Hi Balaji,

I wondered if you could give me a little more information about your hardware set up.  Are these two screens running off a single computer?  Or are they touch panels?  I am a little unclear about what you mean by synchronising them.

I just thought an idea for to do this....but i am not done this...

i seen some plants most of there they are using Touch panels or HMI for viewing measurement values for Big screens. even along with they may use PC for controlling and logging the data.

i just thought about now only, may be possible with labview....

i just asking to you, i have single CPU two monitors , one screen to show main vi and others (Monitor) screens to show mesurement values

Hi Balaji,

So if you have an extended desktop across two monitors then I would say you had two options.

1. Within one VI you could simple design the front panel in such a way that it extends across both screens with the relevant information in the right screen.  The fact that there are two monitors present is transparent to the applications.

2. With two VIs there is a property for front panels to choose which monitor they are displayed on.  This is available by wiring a VI reference to a property node and selecting front panel window >> monitor.  You then enter an id for the monitor you want it to be displayed on, this is a numeric e.g. your primary monitor will be zero. You can see the property node help page here. 

I hope this is the information you are after.

Hi,

I have just tested your code and it didnt work at first but it seems that perhaps windows doesn't zero index it's monitors so I would suggest trying references 1 and 2 and see if that works for you.

Also I attach your code using a this VI reference instead of open reference, this will ensure it will work on any machine as well as if you move the VI.
