5.1 KL6001 - Terminal configuration
The terminal can be configured and parameterized via the internal register structure.
Each terminal channel is mapped in the Bus Coupler. Depending on the type of the Bus Coupler and the
mapping configuration (e.g. Motorola/Intel format, word alignment etc.) the terminal data are mapped in
different ways to the Bus Coupler memory.
To parameterize a terminal, it is necessary to map the control/status byte.
BK2000 Lightbus Coupler
In the BK2000 Lightbus Coupler, the control and status byte is mapped in addition to the data bytes. This is
always in the low byte on the offset address of the terminal channel. With the KL6001, the C/S byte is used
exclusively in register mode. The Ser. control and status byte is used for the handshake protocol.

BK3000 PROFIBUS Coupler
With the BK3000 Profibus Coupler, the mapping of the KL6001 in the Bus Coupler is set in the master
configuration software. The KL6001 is delivered in the alternative format. To set the standard format and a
different user data length, please refer to registers 34 and 35. The figure shows the mapping for 4 bytes of
input data and 4 bytes of output data.
