PXIe Cards Reset

[shiksri]

Hello , I want to reset all my PXI SMUs using a single VI . i HAVE MADE A VI FOR THAT BUT THAT VI OPENS A SESSION FOR EACH CARD ,RESETS IT ,CLOSES IT .This takes a significant amount of time in a for loop . Can someone suggest a method where i open a session only once reset all cards ,and close it also at once ,thus saving time as I have 12 cards.

Thanks in advance.

You can use NI System Configuration API instead.

Help >> Find Examples... >> Hardware Input and Output >> System Configuration >> Reset All Devices.vi

You can add an expert filter to filter out the SMU.

You can parallelize the For Loop to speed things up.

The explicit reset seems redundant as the Initialize VI already has a boolean for Reset which you can set to True.

Hi Santhosh,

Thanks .I have been to reduce the time from 62seconds to 27 seconds now with your method to parallelize the for loop . Is there any way to furthur reduce it . I will also try ZYOng method and update you all.

So Santhosh method was fastest among the two solutions I got.

Latest NI DCPower drivers support multi-instrument sessions, try formatting the instrument alias to be comma separated and include all the instruments you want to reset.
