Hi engwei,
In order to implement a script trigger for multiple 6552s I would recommend that you set up the original software script trigger and use the niHSDIO Export Signal.vi to export this script trigger to a desired PXI Trigger/RTSI Line. You can set up the script trigger for each device to occur based on a digital edge and have the source of the trigger be the line that you exported your trigger onto. You can find the signal exporting VI by going to NI-HSDIO>>Generation>>Utility>>niHSDIO Export Signal. You will have a single script trigger that is generated in software and routed to each device over the line you select. The devices will be configured to use the digital edge of this line as their script trigger.

Hi engwei,
I realized that I made a mistake when I was directing you to find the niHSDIO Export Signal VI in my previous post. You should go to NI-HSDIO>>Generation>>Configuration>>niHSDIO Export Signal. I wanted to correct this for you and additional people reading the forum. I have attached a VI that was saved for LabVIEW 8.0 that is a rough example of what I was describing. You should be able to implement this type of configuration to get the functionality you are looking for.

Hi,
I am new to HSDIO and tryin g to do a similar thing.
I tried the example you posted Multi-HSDIO Script Trigger1.vi 92 KB. When I send the software trigger I can see the output waveform on One 6552 hsdio but it didn't trigger the other HSDIO module card in my PXI system.
If you can provide me a link or example how to set the pxi trigger for mutli card 6552 in a pxi1042Q system.
Thanks
