Is there a way to pass/resend a message that comes in on Can1 (1000mbps) to Can2 (500mbps)

I currently have some modules on CAN2 that Id like to pass a message that comes from another device on CAN1.

You can create a CANbus Input for the data received on CAN1 and then forward it on CAN2 using CANbus Export.

Guess I was overthinking and don’t have my Racetrack PC with me to look.

So basically build a Can2 export and use the Can1 input as variables to send just like any other variable.

Here’s hoping I don’t run out of name space and CAN lines.
