This tab controls what additional information is stored by analysis with regards variables extracted from DBC file references. While DBC files contain all the required information to defined how data is sent on the CAN data network, it doesn’t contain any information about filtering or samples rates etc. This information is stored by analysis in a seperate file.
This information is updated whenever you make a change to a DBC based CAN variable in the variable manager.
This information is stored by the variable name, When a DBC based CAN variable is laoded with a matching name then the additional variable information is automatically applied.
You can remove the additional variable information by right clicking on the signal in this tab.
for more information, please refer to this page: Managing CAN Variables
