CANopen: configure and device testing

Abstract

The paper describes an European field bus communication standard developed during ESPRIT IV project 7302 and subsequently has become known as CANopen. CANopen Configure Device and Test (CDT) software has been developed by Newcastle University (UK) to facilitate the configuring and testing of CANopen devices. The CDT is further enhanced to perform conformance testing of I/O devices. To operate the software requires a PC running Windows and a CAN card supporting CANopen. It allows the use of any CANopen compliant object dictionaries to communicate with the device. Any object can be read or written, for both service data and process data communications. Synchronisation messages can be generated automatically, with real time display and control of synchronous data. Full CANopen network management services and life guarding are implemented and there is an object dictionary editing facility.
