CiA 450 specifies CANopen interfaces for generic and liquid (rotodynamic) pump devices. It is based on the bus-independent profile for vacuum and liquid pumps developed by VDMA (the German Mechanical Engineering Industry Association). The VDMA profile should be consulted simultaneously with the CiA 450 profile. Thus, VDMA-compliant pumps using different networking technologies can be easily combined within one system. The specified application data is then exchanged via corresponding gateways. Device manufacturers may supply diverse markets with pumps implementing the same electronic interface according to CiA 450 and simply vary the appropriate application software. Usage of standardized CANopen interfaces allows monitoring, inspection, and diagnostics of the networked devices using off-the-shelf tools.
