3rd CAN XL plugfest and CAN XL technology day

End of April, the 3rd CAN XL plugfest organized by the nonprofit CiA (CAN in Automation) international users’ and manufacturers’ group took place in Troy, Michigan.

CAN XL is the 3rd CAN (Controller Area Network) protocol generation. On the plugfest, IP (intellectual property) core implementations from Bosch, Kvaser, and Vector were tested on interoperability. On the 2nd CAN XL plugfest in 2022, a micro-controller prototype from NXP and an IP core from Fraunhofer/Cast have been already successfully tested.

In the afternoon session, different topologies have been used. Point-to-point and linear networks with short unterminated stubs achieved a data phase bit rate of up to 20 Mbit/s. The arbitration bit rate was 500 kbit/s. The connected nodes used CAN SIC (signal improvement capability) XL transceivers from Bosch, Infineon, NXP, and Texas Instruments. The achieved results are shown in the attached figure.

One day after the plugfest, CiA held a CAN XL technology day. The speakers introduced into the CAN XL ecosystem and several CiA members showed demonstrators (Bosch, C&S group, NXP, and Vector) as well as oscilloscopes with CAN XL decoder and trigger functionality (Keysight, Rohde & Schwarz, and Teledyne). The presentations covered base information on protocol and physical transmission as well as network design hints, embedded security (e.g. CANsec), etc. CiA plans a similar event on June 22 close to Paris.
