Can pack with two multiplexors

Hello I need to use a Can pack block to send a CAN signal with two multiplexor to an ECU (hardcoded message) but the Can pack block doesnt accept it and only considers the first one in alphabetical order, will this issue be resolved soon? Is there any prctical workaround? Thanks

Hi Enzo,

I am assuming that you are using the ‘CAN Pack’ block from the Vehicle Network Toolbox and that you are trying to pass two signals with multiplex type “Multiplexor”.

Unfortunately, you can only specify one ‘Multiplexor’ signal in the ‘CAN Pack’ block. The single signal of type 'Multiplexor' is used to select from the signals of multiplex type ‘Multiplexed’. Multiple signals cannot be used to determine this, hence the limitation.

To demonstrate this, I have attached a model which contains two ‘Multiplexed’ signals being selected by a “Multiplexor” signal which can be chosen between a pulse wave and its inverted pulse wave using a manual switch.

I hope this resolves your issue. For detailed information on how to use the ‘Can Pack’ block, do refer its documentation:
