Hello Niklas,
I am assuming you are using either "C2000 Microcontroller Blockset" or "Embedded Coder Support Package for Texas Instruments c2000 Processors" based on the Matlab release.
I have tried to answer your questions based on following assumptions since your questions are generic in nature.
- "Implemented a CAN Com between two Launchpads, i could not use the external mode anymore. "
As far as i know you should have been able to run external mode even with CAN communication established between two launchpads , any screen shot on error experienced would also help in answering better.
- " Is it possible to use external mode over CAN while CAN Bus is also used to communicate over inverters "
You should be able to use external mode over CAN on a given simulink model even with additional CAN nodes in the CAN BUS. I have attached following documentation links for all the signal monitoring-parameter-tuning supported on C2000 to help you better .
