The CAN in Automation website has all the CANopen sepcifications.

http://www.can-cia.org/

However the specifications you require are in the members only section, and to access that you need to pay an annual subscription, which I think is about £3k

    \$\begingroup\$ Makes one wonder what the "open" in CANopen is really supposed to mean. \$\endgroup\$ – Olin Lathrop Jul 16 '11 at 16:53

    \$\begingroup\$ The CiA is a non-profit organisation, however, the engineers still have to get paid! Its open in the sense of the basic specs are available to all, but if you want to do anything outside of this then you need the specs, especially if you are selling equipment as 'CANopen compliant'. For the hobbyist its not really practical. \$\endgroup\$ – BullBoyShoes Aug 12 '11 at 20:02
  • \$\begingroup\$ Plenty of the specs are available for free from CIA if you just fill in some form. Been quite a while since I ordered the documents myself, but back in the days you could just buy all the specs on a CD without being a CIA member. It certainly didn't cost £3k. As for the case of CIA 304 it is apparently an EN standard nowadays, meaning you should be able to buy it from a standard institute. \$\endgroup\$ – Lundin Oct 24 '13 at 15:10
  • \$\begingroup\$ Regarding "selling as CANopen compliant", you would want to have CIA act as 3rd party test house and guarantee conformance. After that, your product can be sold as certified for CANopen and it will appear on the list of all certified devices. \$\endgroup\$ – Lundin Oct 24 '13 at 15:14

can-cia.org will supply specifications by email to non-members, membership allows you to directly download them from the site. I can't seem to see Cia302, or Cia304, but Cia305 is here: http://www.can-cia.org/index.php?id=915&no_cache=1
