SDO Service Data Object
CANopen SDO transfers are used for low priority reading and writing of device parameters and objects.
SDO Upload (read from device) and
SDO Download (write to device) specifications define different standard methods of reading and writing different types of data, including
optimized transfers for large blocks of data.
PDO Process Data Object
CANopen devices produce or consume PDO CAN frames. They are used for fast data transfer of critical process data. Before using PDO
transfer, the CANopen device must be configured, i.e. the content of the PDO object must be defined (PDO Mapping). Two types of PDOs are
defined for CANopen:
Transmit PDO (TPDO) - process data produced by the device node, e.g. status and position information.
Receive PDO (RPDO) - process data consumed by the device node, e.g. control command.
XDD / XDC
XXML Device Description File (. xdd) / XML Device Configuration File (.xdc).
XDD files contain a dictionary of device functions and parameters and supersede the classic .eds files (Electronic DataSheet).
XDC file in addition contain parameter values for device configuration and supersede the .dcf file format (Device Configuration File).
Qt Quick / QML
Qt Quick is a new user interface (UI) technology and development kit for creating rich, attractive user interfaces in minimum time. QML is a
declarative user interface language based on Javascript. It describes how user interface elements look and how they behave. Kickstart
projects can make use of
Qt Quick technology to build custom designed screens and attractive end user applications.
RS485-interface
The RS485 interface is a wired bus system for serial data transmissions. The transmission takes place via 2 wires. The digital signal is
transmitted via these wires in differential form. In this way common-mode interference is suppressed effectively.
RS485-Communication
Communication between users and the drive software takes place via so-called telegrams. Each program contains specified data, which has
to be received or sent. The drive software ignores telegrams that are not addressed to it.
