Device profile for pumps

CANopen device profile for pumps (CiA 450) released

The Task Force (TF) pumps of the CAN in Automation (CiA) international users’ and manufacturers’ group has published the version 1.0 of the CANopen device profile for pumps (CiA 450). The profile specifies the CANopen interfaces for generic and liquid pumps. On request, the CANopen interfaces for process vacuum and turbo vacuum pumps will be specified, too. The specification is based on the bus-independent profile for pumps developed by VDMA (German association of machine builders).

The profile defines the pump configuration data, control and status information as well as the values measured by the pump electronics. Operation behavior of the pumps is controlled via the defined state machines. Via Emergency messages failures, warnings or alarms are indicated to the user. Also multiple pumps may be operated via the same CANopen interface. The profile is currently available for CiA members.
