CiA® 510: Mapping of SDO and EMCY protocols to J1939

The CiA 510 document specifies the mapping of CANopen protocols to J1939 parameter groups (PGs). The CAM11 and CAM21 parameter groups contain the SDO protocols as specified in the CiA 301 CANopen application layer and communication profile, also known as CANopen CC. The CEM parameter groups map the EMCY protocol as given in CiA 301.

The mapped SDO protocols give the user access to the CANopen object dictionary implemented in devices providing CiA profile functionality. The CEM parameter group provides alarms and warnings in real-time as used in CANopen CC.

PDOs can be mapped to proprietary PGs or to PGs with by SAE uniquely assigned PGNs (PG numbers). The CAM11, CAM21, and CEM parameter groups use registered PGNs (see J1939/DA). This means, J1939-connected devices can virtually run CiA profiles including configuration functionality.

CiA 510 version 1.1.1 J1939 parameter groups for SDO and EMCY
Scope

This document specifies the mapping of CANopen application layer protocols to J1939 parameter groups. This includes, in particular, the mapping of SDO (service data object) client and SDO server protocols. Additionally, this document specifies the mapping of the EMCY (emergency) protocol. The mapping of CANopen profile-specific PDOs is not in the scope of this document.

CiA 301 version 4.2.0 CANopen application layer and communication profile
Scope

This specification specifies the CANopen application layer. This includes the data types, encoding rules and object dictionary objects as well as the CANopen communication services and protocols. In addition, this specification specifies the CANopen network management services and protocols. This specification specifies the CANopen communication profile, e.g. the physical layer, the pre- defined communication object identifier connection set, and the content of the Emergency, Time- stamp, and Sync communication objects.
