Parameterization
In the TwinCAT System Manager an EM37xx is parameterized via two dialog windows. Dialog box (A) shows the process data that can be parameterized based on the CoE directory (B).

- 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.
