Nuremberg, Germany, February 5, 2010. CAN in Automation has released the CiA 102 and 103 CAN physical layer specifications for industrial automation respectively intrinsically safe capable communication as Draft Standards. The free downloadable CiA 102 specifies bit-rates for CAN high-speed networks compliant with ISO 11898-2 or ISO 11898-5. The specification also includes some guidelines for the physical medium attachment (PMA) sub-layer, and the medium dependent interface (MDI) sub-layer. This covers device and system design hints.
