CiA^® 416: CANopen application profile for building door control systems

The CiA 416 application profile specifies the communication within an embedded building door control system. The node-ID claiming procedure unburdens the system designer from assigning unique node-IDs to each CANopen device. Each CANopen device compliant to CiA 416 provides one default PDO to be broadcast to all other devices in the network. This requires 126 default PDOs to be received.

To prevent a forbidden access to the object dictionaries of the CANopen devices, password protection was introduced. In addition to that, the application profile specifies an encrypting procedure for the transmitted process data.
CANopen devices compliant to CiA 416 may implement one or more functional elements (virtual devices). Examples for virtual devices are locking, opening, fire alarm, key cylinder, identification, etc. The system integration can be supported by powerful tools, which provide an automatic or semi-automatic device configuration.

The CiA 416 specification consists of several parts:

• Part 1 describes general definitions and the basic principles (including node-ID claiming procedure)
• Part 2 specifies the virtual devices
• Part 3 specifies PDOs and application objects (process data and configuration parameters)
