How to change data dictionary entry through matlab script without altering the storage class?

Hi,

I am trying to change multiple entries in the data dictionary for a particular model. Instead of copy pasting every time, I would like to create a script for doing this automatically everytime. This is the script I am using right now:

BPPR_sldd = Simulink.data.dictionary.open('BPPR_ac.sldd');
dDataSectObj = getSection(BPPR_sldd,'Design Data');
a = getEntry(dDataSectObj,'KtBPPR_I_I2chr');
setValue(a,single(cal_I2c)); 

The issue here is that when I do this the parameter changes its storage class and becomes a generic constant when setValue is used. See figure for reference:

Do not cast the DataType during the assignment.for example:

>> x = Simulink.Parameter

x =

Parameter with properties:

Value: []

CoderInfo: [1×1 Simulink.CoderInfo]

Description: ''

DataType: 'auto'

Min: []

Max: []

Unit: ''

Complexity: 'real'

Dimensions: [0 0]

The DataType is 'auto'. Assign the value:

>> x.Value = 12

x =

Parameter with properties:

Value: 12

CoderInfo: [1×1 Simulink.CoderInfo]

Description: ''

DataType: 'auto'

Min: []

Max: []

Unit: ''

Complexity: 'real'

Dimensions: [1 1]

The DataType is unchanged. Assign the value using a cast:

>> x.Value = uint16(12)

x =

Parameter with properties:

Value: 12

CoderInfo: [1×1 Simulink.CoderInfo]

Description: ''

DataType: 'uint16'

Min: []

Max: []

Unit: ''

Complexity: 'real'

Dimensions: [1 1]

The DataType changes to 'uint16'.
