Annex
As already described in the chapter terminal configuration, each bus
terminal 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 KL3351 maps itself in the bus coupler depending on the set
parameters.
Mapping in the bus coupler
The KL3351 is mapped in the bus coupler depending on the set
parameters. If the terminal is evaluated completely, the terminal occupies
memory space in the process image of the inputs and outputs.
