How and When Does the attribute VI_ATTR_VXI_TRIG_STATUS get initialized

How and When  Does the attribute VI_ATTR_VXI_TRIG_STATUS get initialized. Do the actual trigger lines get measured or does the attribute get initialized to a default value when the vxi resource manager is executed?

Hey whl6868,

 

According to page 157 (or 3-135) of the manual (http://www.ni.com/pdf/manuals/370132c.pdf), there is no default value for VI_ATTR_VXI_TRIG_STATUS.  If Resman is returning valid values for it, then it must be actually reading the lines.  Else, I would only expect it to return valid values when you actually call the function yourself.
