Function of the KL6301

Operation of the EIB Bus Terminal requires function blocks that are available for downloading from within this documentation.

From firmware version B1 and library version V3.000.000 there are three different modes that can be activated in the KL6301 function block.

Mode 0: 4 filters, each with 64 group entries (compatible with firmware B0 )

Mode 1: 8 filters, each with 32 group entries

Mode 100: Monitor function (all group address telegrams can be received, the KL6301 sends no ACK). Sending is disabled in this mode.

Function of the KL6301 1:

Mode 1 and 100

Modes 1 and 100 can only be used with the basic function blocks from the TcKL6301 library.


The KL6301 sends data individually. This means that a Data variable sent to the KL6301 is sent to the EIB network individually. Subsequent EIB data can only be transferred to the KL6301 after a successful transfer. Two types of EIB telegrams can be sent:


The KL6301 has a maximum of 8 filter addresses. These filters filter the EIB group addresses. Only EIB telegrams entered in the filter are visible in the process image and are acknowledged.

A filter may contain up to 64 group addresses. With 4 filters multiplied with 64 entries a total of 256 group addresses are available. With 8 filters multiplied with 32 entries a total of 256 group addresses are available. The system is configured via a function block. The group addresses are loaded and are immediately active when the Bus Terminal is initialized.

At least one filter has to be parameterized. The type of data is irrelevant for the filter setting.

Monitor function

No filters must be set if mode 100 is enabled. The filters EIB_GROUP_FILTER are simply left empty and not written.
