CAN bus networks with M3000 ® modules can include a maximum of 64 CAN
bus network stations.
ISO/DIS 11898 only specifies networks with up to 30 CAN bus network stations.
As a result, when integrating other devices than M3000 ® modules into a CAN
bus network with M3000 ® modules, the maximum number of CAN bus network
stations might be limited by any existing, older CAN bus drivers.
