CANopen Device Explorer - CANopen Master Tool

CANopen Device Analysis

The emotas CANopen DeviceExplorer is a versatile CANopen master tool for development, testing, diagnostics and service tasks. It provides CANopen master functionalities and allows the analysis and configuration of CANopen devices using a supported PC CAN bus adapter or interface.

Information about each CANopen device is read from the electronic data sheet of the device, or they can be scanned directly from the device. Using standardized device configuration files (DCF) device configurations can be saved or imported. Additionally, data of entire CANopen networks can be stored in project files. The built-in scripting capability using QtScript allows users to create their own test and control applications with only little effort.


CANopen Device Explorer can be purchased together with an EMS. Dr. Thomas Wuensche CPC-USB/ARM7 or CPC-USB/embedded USB CAN Bus Adapter here when the "Buy Now" button is visible:
