Parameterization of K-bus terminals
If a K-bus terminal supports this kind of parameterization, the parameters can be changed via the 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
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
- via AoE access (ADS over EtherCAT) from a TwinCAT system by means of ADS commands on the K-bus terminal
As a rule, it is not necessary to reboot the K-bus terminal after a parameter change; see terminal documentation.
- KS2000 configuration software
The KS2000 configuration software for parameterizing K-bus terminals runs on Windows IPCs and can communicate with the terminals and the upstream coupler via two communication channels: - Internal ADS.
- External via a serial RS232 COM cable or a USB cable. Both are available from Beckhoff. A KS2000 interface at the coupler (e.g. BK1120) is a prerequisite for external access.

![]() | ADS access In contrast to COM access via a cable, ADS access is not limited to the local IPC platform. The routing capabilities of each TwinCAT IPC enable the KL registers to be accessed from other TwinCAT stations. |
