This document specifies compact XML file formats for describing device profiles and communication network profiles for devices used in CANopen FD-based control systems. The content of this specification complies with ISO 15745-1:2003/Amd 1:2007. The part 1 of CiA 1311 specifies the generic set of XML scheme components and rules for describing CANopen FD device and communication network profiles. This generic set is a subset of CiA 311 XML scheme components and rules limited to the mandatory components and extended with the CANopen FD specifics. The annex to the part 1 provides XML-schema files for generation of the generic device description in XDD file format and configuration description in XDC file format. A web resource for the XML scheme namespace and location of scheme files is a work in progress. The part 2 of CiA 1311 is also in progress and is intended to specify the device description and configuration file formats beyond the generic set specified in the part 1 such as handling of modular devices.
