4 Appendix
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 KS2000 configuration software or
using master configuration software (e.g. ComProfibus or TwinCAT System
Manager). The following tables provide information on how the KL1501
maps itself in the bus coupler depending on the set parameters.
