A Standard Communication Protocol - WEG ADL300 User Manual

3. A STANDARD COMMUNICATION PROTOCOL

Civil lift systems use a complex system of operating logic and devices. To achieve the required quality and safety levels,
all devices must be able to communicate by exchanging information and commands.
Communication must be efficient and based on a Bus architecture. CANopen Lift with CiA 417 profile is a standard
communication protocol based on a Bus architecture derived from industrial CANopen version, which allows
communication via a shared language among the various control Devices in the lift system.
Focusing on the part of the system composed of Control Card, Drive and Electric Motor, the Bus architecture can be
represented as follows:
