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.
