Commissioning
Note
EtherCAT System Documentation
The comprehensive description in the EtherCAT System Documentation (EtherCAT Basics
--> CoE Interface) must be observed!
A few brief extracts:
• Whether changes in the online directory are saved locally in the slave depends on the device. EL
terminals (except the EL66xx) are able to save in this way.
• The user must manage the changes to the StartUp list.
Commissioning aid in the TwinCAT System Manager
Commissioning interfaces are being introduced as part of an ongoing process for EL/EP EtherCAT devices.
These are available in TwinCAT System Managers from TwinCAT 2.11R2 and above. They are integrated
into the System Manager through appropriately extended ESI configuration files.
Fig.89: Example of commissioning aid for a EL3204
This commissioning process simultaneously manages
• CoE Parameter Directory
• DC/FreeRun mode
• the available process data records (PDO)
Although the "Process Data", "DC", "Startup" and "CoE-Online" that used to be necessary for this are still
displayed, it is recommended that, if the commissioning aid is used, the automatically generated settings are
not changed by it.
The commissioning tool does not cover every possible application of an EL/EP device. If the available setting
options are not adequate, the user can make the DC, PDO and CoE settings manually, as in the past.
EtherCAT State: automatic default behaviour of the TwinCAT System Manager and

• INIT
• PREOP
