Index Exceeds Matrix dimension error when masking subsystem

1 view (last 30 days)
Hello,
I have a subsystem where I use the CAN Transmit block in the Vehicle Network Toolkit. If I mask the subsystem, I get the error "Unable to query hardware information for the selected CAN channel object. Index exceeds matrix dimensions". If I leave it unmasked, it works fine. I need to use this subsystem multiple times and I would like to mask it so I can make it a library component and adjust the parameters. Does anyone know why CAN transmit doesn't work while masked?
Any help would be greatly appreciated.

Hi Jill,
Yes, it is a bug and has been reported. Can you contact MathWorks technical support and we will be able to give you a workaround for your current release. What version are you running?
Thanks
Shankar

I believe the xPC CAN transmit block has the same problem. It results in a different error, "undefined function or variable" when you try to use the variable name from the mask in a CAN transmit block (I am using the CAN-AC2-PCI from the CAN softing library). Can someone please verify this for me.
Also, just FYI, MathWorks does not have a work around for this. I worked with them on this and the final outcome was it would be put in an "enhancement request" for future releases.
