CANopen profiles

For extruder downstream devices

The nonprofit associations CAN in Automation (CiA) and Euromap have jointly developed the CiA 420 CANopen profiles for extruder downstream devices, also known as Euromap 27.

THE SPECIFICATION SERIES HAS BEEN REVIEWED and new versions have been released. They are available for download free-of-charge from CiA’s and Euromap’s website. The profile specification standardizes the CANopen interface for pullers, corrugators, saws, co-extruders, and calibration-table downstream devices. The first version was introduced in 2002. The updated versions specify a mandatory node-ID allocation scheme, an automatic diameter adaptation for pullers, an improved status-word for corrugators, some functional additions for saws, and corrections as well as clarifications.

Machine builders organized in the Euromap association had initiated the standardization of the downstream device profiles. This series of CANopen profiles allows downstream device manufacturers to develop machine modules, which can be integrated into an extruder production line. Also, production line designers benefit from the standardized interfaces, because they can select machine modules from different companies.

The CiA 420-4 profile for saws now supports a corrugated mode. For this purpose, the actual groove counter parameter and the product groove set value parameter have been added to the CANopen object dictionary. In the saw profile, the resolution of the actual saw counter parameter has been corrected and the early warning length parameter has been inverted.
