CANopen Device Profile for Hydraulic Proportional Valves

The trend towards decentralized concepts in fluidic systems requires effective communication structures between the networked components. Fieldbusses are designed to meet these requirements. When using similar devices from different vendors, a harmonization concerning communication objects and devices’ behavior has to be reached in order to minimize efforts in design and configuration of the whole system. Thus, a bus-system independent device profile for fluidic components has been defined. This profile has been mapped to CANopen. The article describes the profile and the CANopen mapping and the description technique used.
