What began with the Stratos series has now become standard at Wilo: The Wilo-CAN high-speed interface. Wilo-CAN meets the CANopen industrial standard, and is therefore an open system. Since it is a real multimaster bus, it allows for spontaneous communication. This guarantees high dynamics - a standard proven a million times over in the automobile sector.

In order to be able to make use of the high dynamics of the CAN-bus, even in an industrial environment, without high complexity, the CANopen standard provides a mechanism to realize cyclical and result-controlled data transmission. The CAN interface in accordance with ISO 11898 is used, which defines data rates up to 1 Mbit/s.

Based on this, profiles have been developed for various device classes, which ensure the interoperability and standardised use of devices.The device profile CiA 450 defines the properties of liquid pumps. Wilo pumps with a CAN-bus interface already meet the basis of all device profiles, the CiA DS 301. With the help of electronic data sheets (.eds files), it is easy to use with commercially available PLCs or CANopen bus configurators.
