The new CAN FD standard (CAN with Flexible Data rate) is primarily characterized by higher bandwidth for data transfer. The maximum of 64 data bytes per CAN FD frame (instead of 8 so far) can be transmitted with bit rates up to 12 Mbit/s. CAN FD is downward-compatible to the CAN 2.0 A/B standard, thus CAN FD nodes can be used in existing CAN networks. However, in this case the CAN FD extensions are not applicable.
The monitor software PCAN-View and the programming interface PCAN-Basic for the development of applications with CAN connection are included in the scope of supply and support the new standard CAN FD.
ISO / Non-ISO CAN FD:
PEAK-System takes this into account by supporting both protocol versions with their CAN FD interfaces. If required, the user can switch to the CAN FD protocol used in the environment by software („Non-ISO“ and „ISO“). Devices delivered until February 2015 need a firmware update for this functionality.
