EtherCAT with CANopen or PROFIBUS
Addressing EtherCAT nodes using CANopen/PROFIBUS nodes
In the »PLC Designer«, the output and input objects are "byte-addressed". The original
address offset of ’1000’ (word level) for the first output and input objects is set accordingly
to '2000" after the import of the EtherCAT configuration. The addresses of the other input
and output objects are also updated.

Note!
• Changes of the EtherCAT configuration in the »PLC Designer« are overwritten
when the EtherCAT configuration is re-imported.
Always adapt the EtherCAT configuration to the »EtherCAT Configurator«.
• In a mixed operation, it must always be ensured that the CAN-Motion task
has the highest priority. The task assigned to the EtherCAT bus should have
the second-highest priority. The tasks assigned to the Logic bus systems
should be configured with a lower priority.
