CiA® 461 series: CANopen profile for weighing devices

The device profile family for weighing devices specifies the CANopen interface including the PDO mapping and the necessary configuration parameter. Part 1 and part 2 were released CiA-internally as Draft Standard Proposal (DSP) in summer 2015.

Part 1 of this series provides some general definitions including several legal for trade (LFT) modes. It describes also the data encryption and data exchange procedure. Additionally, the sealing and the password changing procedure are described briefly. Of course, this part specifies some common communication parameter of the CANopen interfaces for weighing devices.

Part 2 specifies the CANopen interface for load cells. Load cells are transducers that generate an electrical signal with a magnitude proportional to the measured force. Eight device classes are described. The profile specifies several compensation techniques for gravity, inclination, temperature, and movement acceleration. In case of external compensation, the compensation values are mapped into the four default RPDOs. The two specified default TPDOs provide the load cell weight output value plus weight status and alarm information, respectively the weight status and the process data random number as well as the process data signature. The configuration parameters include the data sample rate and filter settings, for example, for Bessel, Butterworth, or Notch characteristics.

Part 3, which has not yet been developed, will deal with scale devices.

Part 4 is intended for special human machine interfaces and indicator devices related to weighing applications.
