Parameterization with KS2000
The KS2000 configuration software can be used for parameterizations via the serial interface of the
Bus Coupler, independent of the fieldbus system.
5.2 Mapping in the Bus Coupler
As already described in the Terminal Configuration section, each Bus Terminal is mapped in the Bus
Coupler. This mapping is usually done with the default setting in the Bus Coupler / Bus Terminal. The
KS2000 configuration software or a master configuration software (e.g. ComProfibus or TwinCAT System
Manager) can be used to change this default setting.
If the terminals are fully evaluated, they occupy memory space in the input and output process image.
The following tables provide information about how the terminals map themselves in the Bus Coupler,
depending on the parameters set.
5.2.1 Standard format
The KL5121 is mapped into the bus coupler depending on the set parameters. The terminal always occupies
memory space in the process image of the inputs
and outputs.
