CANOpen Device profile for generic I/O modules

This specification represents the CANopen device profile for generic digital and analogue input and output modules. Devices compliant to this specification use communication techniques, which conform to those described in the CANopen application layer and communication profile specification. In addition, programmable I/O devices may use communication techniques, which conform to those described in the CANopen additional application layer functions. In the appendices, some specific I/O devices are defined.

CANopen application layer and communication profile

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 predefined communication object identifier connection set, and the content of the Emergency, Timestamp, and Sync communication objects.
