Parameterization and commissioning
BK11x0, BK125048 Version: 4.1
Fig.34: TwinCAT setting for using this component as reference clock
Note
Activation of Distributed Clocks support
The (synchronization) procedure described here is only successful for the components de-
scribed above. The checkboxes can be set for other components, too, although the hard-
ware does not support this function, unless specified in the respective documentation. In
particularly, please note that after commissioning the component may not be replaced with
a previous version without DC support.
6.3 KL register communication
6.3.1 Parameterization of KL terminals
If a KL terminal supports this kind of parameterization, the parameters can be changed via the KL register
communication. The parameters are managed in so-called registers in the terminal.
They can be changed during the startup phase or online during operation.
The available parameters/registers are described in the corresponding terminal documentation. In these
chapters, only the route to the registers via EtherCAT is described.
The following 3 routes are available; all require the coupler as a gateway:
• Change during the EtherCAT startup phase via the coupler’s CoE startup list [}50]
This ensures that the terminal is parameterized correctly and immediately, even after the terminal is
exchanged.
• Change during operation
◦ via EtherCAT CoE access to the coupler
