Is it Possible to Edit FIBEX for Ethernet with Vector FIBEX Explorer Pro?
No, it is not. As AUTOSAR format ARXML will in long term replace the FIBEX format for Ethernet based network description, no development effort has been made in extending the Vector FIBEX Explorer Pro that is only adapted for FlexRay networks.
To edit FIBEX for Ethernet we recommend the usage of third part editors, for instance Altova XMLSpy. Together with the Standard for FIBEX, you can obtain by ASAM the corresponding XSD schema that will help you to work with XMLSpy.
