EL30xx parameterization
An EL30xx is parameterized via two dialog boxes/tabs in the TwinCAT System Manager, the Process Data tab (A) for the communication-specific settings and the CoE directory (B) for the settings in the slave.

- Changes to the process data-specific settings are generally only effective after a restart of the EtherCAT master:
Restart TwinCAT in RUN or CONFIG mode; RELOAD in CONFIG mode - Changes to the online CoE directory
- are in general immediately effective.
- are in general stored non-volatile only in the terminal/in the slave and should therefore be entered in the CoE StartUp list. This list is processed at each EtherCAT start and the settings are loaded into the slave.
