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 KL3064
maps itself in the bus coupler depending on the set parameters.
Mapping in the bus coupler
Mapping in the bus coupler The KL3064 is mapped in the bus coupler depending on the set parame-
ters. If the terminal is evaluated completely, the terminal occupies memory
space in the process image of the inputs and outputs.
