Error evaluating 'InitFcn' callback of Battery block (mask):

Hi,

While I triedto use battery from Simulink library an error pop ups:

Error evaluating 'InitFcn' callback of Battery block (mask) 'MMC_20SM_CAP_MOSFET/CELL 1/Battery'. 
Callback string is 'BatteryCback(gcb,1)'

Caused by: Invalid setting in masked block 'MMC_20SM_CAP_MOSFET/CELL 1/Battery' for parameter 'MaskEnables'

Can any one assist to undrstand/solved this problem?

Thanks,

Tommy

Can you share which release of MATLAB are you using?

Hi @Tommy,

The error message you are encountering indicates an issue with the initialization function (‘InitFcn’) of a masked block in the Simulink model. This error is related to the ‘Battery’ block within the model, which is located inside the ‘CELL 1’ subsystem. The error seems to be with how the mask parameters are set or managed. You can try the following steps to troubleshoot and resolve the issue:

1. Open the block mask editor for the ‘Battery’ block by right-clicking on the mask and selecting ‘Mask > Edit Mask’. Then, navigate to the ‘Initialization’ tab and examine the ‘BatteryCback(gcb, 1)’ function. Please note, that ‘gcb’ returns the path of the current, or most recently clicked block. In order to get the correct path for the block, make sure that you have selected the desired block. Alternatively, you can give the path to the block directly, to avoid any issues during execution. Ensure that this callback function is correctly defined and that all variables and parameters it references are available and correctly initialized.
2. Ensure that the ‘MaskEnables’ property of the mask is correctly set. This property controls which parameters are enabled or disabled based on other parameter values. The value of this property needs to be a cell array of character vectors, each either 'on' or ‘off'. You can access or modify this property by using the ‘get_param’ and ‘set_param’ functions in MATLAB.
