Issue Details

I created model in VeriStand which consist of array data type for inport and outport.

TestStand is able to recognize the array data type using Framework Set/Get Variable Values step and the check expression shown no error. 

However, it shown error when I execute the TestStand sequence, which similar as below shown:

Solution

ASAM XIL Steps for NI TestStand only support inport and outport as Segment into scalar channels, it will pop out error when it set as Maintain as vector channel.

Kindly make sure Vector port specification is configure as Segment into scalar channels.

Additional Information

Model parameters is supported set as Segment into scalar channels and Maintain as vector channel.
