Scan Engine not working with 9375 or other modules with only read and only write modules. #69
Description
When writing to a DO of a 9375 it will throw error -66229.
This happens because we try to write at module level but the module has some read only ports and it will throw the error.
To fix it we need to change :
C:\Program Files (x86)\National Instruments\LabVIEW 2020\vi.lib\NI\DCAF\Modules\scan engine\execution\create_module_map.vi
In here we need to check if all variables are writable and readable

I have a 9375. I have workaround the issue with almost the same solution. I'm doing a read and write and check if I get the error -66229. In fact, we have the error because we don't filter the DO to write.
I think that it can be fixed and make it possible to use the IO scan feature on this module. We just need to filter the DO to write in the output.vi. I didn't really try it in this way because it can be dangerous on my system if I changed the wrond DO but I will appreciate to have this feature working well. We have 16 DO to write and 16 to read, using scan can be good to reduce CPU usage.
Does anyone can handle this ?
