Hello,
I have created a very simple custom step type, which has a dll module. The dll has been compiled in LV2010. The function in the dll receives a "Config" cluster from TS, and returns an array of numbers.
The Config container is a custom data type, passing this to the DLL is working.
The returning array of numbers has also a custom data type, as it should be handles as a LabView array. In the custom step type I have added a "Response" variable of this custom data type. Additionally, I have added a local variable in the MainSequence of this custom data type.
Both custom data types I have created according to this knowledge base.

And now comes the point: on the specify module page, I can select the TestStand variable, where the returning array should be written. It is working, if the returning array goes to the local variable. But it doesn't work, if the returning array will be passed to the Step.Response variable. The Step.Response variable has the same type, as the local variable. So why doesn't it work with the Step.Response??? In this case, the Step,Response array stays empty.
Attached you find a sequence with both working and not working steps.
