CANopen profiles for laboratory automation

(PresseBox) (Nuremberg, ) CAN in Automation (CiA), the international users' and manufacturers' group for CAN (Controller Area Network), has released additional device interfaces for laboratory automation. The CiA 434 specifications (part 2 and part 3) describe device profiles for heating, cooling, and shaking units as well as dispensers, dilutors, and pumps.

The profiles specify process data and configuration parameters. This makes the device in a CANopen network interoperable and even partly exchangeable. This simplifies system design.

CANopen is an internationally standardized communication system (EN 50325-4), which is used in many different application fields. The CANopen profiles for laboratory automation have been developed by marketleading companies and are designed especially for pipette automation systems, but are also suitable for other laboratory equipment. In such systems, IEC 61131-3 programmable devices are increasingly used, which are originally developed for industrial automation. The CiA 434 specification has been published CiA internally; excerpts are available for nonmembers.
