I believe you have a race condition at the very least. You may be able to fix the FIRST problem by wiring the digital output data from where you are generating it directly to the input of the DO function and eliminate the read from the local variable.

 

Just my 2 cents,

Could the answer be that you have only configured the task for port 0

Hi Andrea,

 

since I saw that you are working with ABB, you can go to this homepage:

 

www.ni.com/abb

 

This is an ABB user group, where you have to apply first, and where you can access a lot of resources from ABB and also visit the LabVIEW Core 1 and Core 2 as well as the Data Aquisition and Signal Conditioning Course, which will help you a great deal with your architecture and also will show you how to address your hardware.

If you need more information on how to access it, just call at NI and mention your Service Request Number 2676014.

Best regards, Niko
