At a Glance
In order to implement a CANopen bus, it is necessary to define the physical context of the application in which the bus is integrated (rack, supply, processor, modules), and then ensure that the necessary software is implemented.
The software is implemented in two ways with Control Expert:
Implementation Principle
The following table shows the different implementation phases:
