Developing CiA specifications
CiA interest groups (IG) and its related special interest groups (SIG) develop all CiA specifications and CiA recommendations as well as CiA implementation guidelines and CiA application notes. It starts always with a New Work Item Proposal and may end in the release of a public-available document.
The detailed development process is available here.
There is a defined development process adapted from international standardization bodies. Documents in public-available state can be downloaded free-of-charge also by non-members from this website.
The released CiA specifications and other CiA documents comprise more than 20 000 DIN-A4 pages. The defined CANopen device, application, and interface profiles enable the implementation of interoperable products. Users as well as product developers benefit from the jointly developed documents.
CiA members may participate in any technical group. They just need to register at the CiA office. But also not-registered members may comment any CiA document during the entire development process.
CiA Technical Committee
The permanent Technical Committee (TC) members are elected annually by the General Assembly and each Interest Groups (IG) nominates additional members. The TC coordinates the technical work of all CiA technical groups, in order to avoid double specifications. In addition, the TC ratifies all public available CiA technical documents.
Interest Group CANopen
The Interest Group (IG) CANopen coordinates all CANopen Special Interest Groups (SIGs) and their related Task Forces (TF). It develops the general guidelines for profile specifications and approves Draft Standard (DS) documents. Each CiA member may participate in the IG CANopen.
Interest Group CAN FD
The Interest Group (IG) CAN FD accompanies the international standardization of the CAN FD protocol (ISO 11898 series). In addition, it specifies additional implementation guidelines and application nodes. This includes system design recommendations for different application fields.
Downloading CiA documents
Non-members can download all publically available documents (specifications, recommendations, and application notes) only. Members also have access to CiA Draft Standards (DS), CiA Draft Standard Proposals (DSP), and all other CiA internal documents.
Some CiA Draft Standards – mainly those related to CAN FD and CANopen FD are also available for non-members at a lump sum of 499,00 € per document plus German VAT.
