CANopen-Lift within the lift industry

At the Interlift fair in 2001, several manufactures of lift components agreed on an initiative to harmonize the protocols used in CAN-BUS systems. After that CANopen started to become a standard for the automation within the lift building industry.

The CAN-in-Automation organization (CiA) reviews and controls all projects worldwide where CANopen systems are involved. A Special Interest Group (SIG) was established to develop further CANopen based standards with regard to the communication between devices and components used in the lift building industry.

CANopen-Lift is an open and standardized protocol to harmonize the communication between the various devices used in lift building and lift control.That means that CAN-Bus based devices and components of different manufactures can be combined into one overall system without any problems.

The application profile of the CANopen standard is subject to continuous improvement. W+W wants to contribute to that with its offering of pre-assembled wirings and devices for the connection of various components of CANopen-Lift products. If requested by the customer, the pre-assembling can always be adapted to special customer requirements.

Meanwhile CANopen has become the leading standard in Europe and more and more companies contribute to the further development of CANopen-Lift. It is sure that this system will offer a lot of new capabilities and applications in the future.

Technical information

General information

The assembled cables and elements are used for the connection of different components of CANopen-Lift products. It generally applies:

• Length of the BUS (main line): ≤ 250m (at baud-rate 250kBits/s)

• Design the stubs as short as possible: ≤ 6m (at baud-rate 250kBits/s)

• Stub lines must not be longer than 60m in total.

• Stub lines longer than 60m in total: With the prior consent of the control manufacturer a repeater or a second power supply may be needed.
  

• At most 127 participants (knots) at each BUS.

• The BUS has to be closed with a terminating resistor of 120Ω at both ends, to avoid reflexions.

   This is also necessary at very short cable length!
