CANopen Fieldbus system
What is CANopen?
CANopen is an open fieldbus standard based on CAN which is used mainly in automation technology. CANopen enables communication between devices made by different manufacturers without any special interface adaptations.

CANopen Master Simulator
The CANopen Master Simulator is a simple, universal tool for exchanging data with CANopen slaves from virtually any manufacturer without a CANopen master, by just using a PC and the delivered hardware. Input data can be read and output data written without any additional entries or files.
In addition, the CANopen Master Simulator can be used of course to read and write special objects. It is also possible to search a complete CANopen line for any connected slaves. The digital I/O data are represented in hex and binary as well as ASCII characters. Analog I/O data are represented in decimal. Output data can be sent consistently.
Included with the CANopen Master Simulator package is the CAN dongle. The CAN dongle is the ideal interface converter between the USB port on the PC and CANopen. The dongle is very compact and is powered by the USB port on the PC. This also makes it ideal for portable use with a laptop or notebook.
