CiA® 420 series: Profiles for extruder downstream devices

Members of CiA and Euromap have jointly developed a set of CANopen profiles for extruder downstream devices, e.g. pullers, corrugators, saws, calibration tables, and co-extruders. Such devices come with NMT slave functionality only. The master-extruder provides the NMT master and slave functionality. It consumes all Heartbeats and EMCY messages from the downstream devices.

The CiA 420 set of profiles allows an easy system integration of downstream devices from different vendors. Euromap provides additional specifications for local non-CANopen interfaces. This includes specifications for emergency-off-wiring, the wiring of a discrete measuring wheel interface, or the wiring of non-CAN interfaces for saws.

The CiA 420 series specifies CAN bit-rates, connectors, cabling, and node-IDs. Of course, PDO communication and mapping parameters are specified for different downstream devices, too. It is necessary that all PDOs support synchronous transmission respectively synchronous reception. The SYNC cycle-time is specified with 20 ms.

The downstream device receives the control-word mapped into a RPDO and transmits the corresponding status-word mapped into a TPDO. Additionally, the PDOs contain several set process values respectively actual process values. This means that master-extruder commands are confirmed on the application level. Configuration parameters are written and read by means of the SDO default channel.

  • Part 1: General definitions (including connector and node-ID assignment)
  • Part 2: Puller
  • Part 3: Corrugator
  • Part 4: Saw
  • Part 5: Co-extruder
  • Part 6: Calibration-table
