Annex
As already described in the chapter terminal configuration, each bus termi-
nal is mapped in the bus coupler. In the standard case, this mapping is
done with the default setting in the bus coupler / bus terminal. This default
setting can be modified with the Beckhoff KS2000 configuration software or
using master configuration software (e.g. ComProfibus or TwinCAT System
Manager). The following tables provide information on how the KL6051
maps itself in the bus coupler depending on the set parameters.

Mapping in the bus coupler The KL is mapped in the bus coupler depending on the set parameters.
The terminal occupies memory space in the process image of the inputs
and outputs.
