Iveco has developed a gateway to connect the CAN in-truck networks to the CAN-based body network. The device complies with the CiA 413 CANopen truck gateway profile. It comes with all trucks of the Italian brand, which is owned by CNH.
THE CANOPEN GATEWAY COMES PRE-CONFIGURED by Iveco or it can be customized by the body-builder. In general, the gateway provides most of the CiA 413 signals as well as some Iveco-specific signals. This is more than J1939 has specified. The so-called public configurations are developed jointly with key-users for specific applications (e.g. winter service equipment or concrete mixer). The PDO pre-configuration for refuse collecting vehicles complies with the CiA 422 truck gateway specification used by several European refuse collecting vehicle providers. For unspecific body applications there is a generic pre-configuration available, which complies with the J1939 PGNs. Body-builders with CANopen knowledge (e.g. truck-mounted cranes) can configure the gateway themselves (private configuration) using a dedicated tool provided by the truck maker or Iveco will do it for the customer. The tool supports the XDD format for EDS (electronic data sheets in XML).
Since Euro6 all vehicles ordered with CANopen (OPT0384) will be delivered with the “Iveco default CAN communication”. Such default communication is closely aligned to J1939 standard, completed by some Iveco proprietary messages. This means, the CANopen PDOs are transmitted periodically with 29-bit identifiers, emulating the J1939 protocol. In this case, the PDOs are not optimized for the body application.

The gateway implements also some safety functionalities. The user can configure the behavior for the CANopen NMT stop state. Additionally, the gateway acts as a firewall between body network and in-vehicle networks. The CANopen gateway is pre-configured with the CANopen node-ID of 112, and the bit-rate is preset to 250 kbit/s. By default, the gateway provides NMT master functionality, starting with clamp 15 automatically to NMT operational state.
