Problem using field of structure parameter as constant block value.

After creating a structure parameter like this:

FTIP = Simulink.Signal;

FTIP.CoderInfo.StorageClass = 'ExportedGlobal';

FTIP.DataType = 'Bus: FTIPBus';

FTIP.Complexity = 'Real';

FTIP.Dimensions = 1;

FTIP.DimensionsMode = 'Fixed';

FTIP.SamplingMode = 'Sample based';

FTIP.InitialValue = 'FTIPStruct';

I can display a field in the matlab command window like this:

FTIP_Param.Value.Gain1

ans = 10

But when I use the same 'FTIP_Param.Value.Gain1' as the value of a constant block I get the error: 'Structure field Value not found'

 You didn't state this, but I assume that RTIP_Param is a Simulink.Parameter?  If so, try using RTIP_Param.Gain1. In this case, the "Value" is not needed when accessing the data object.

Yes, sorry I included the wrong definition example (I had tried using a Simulink.Signal originally). I did create FTIP_Param as a Simulink.Parameter and then I set the 'Value' to a structure (FTIPStruct). And I did try accessing it in the constant block as FTIP_Param.Gain1 with no luck.
