Mapping
As already described in the Terminal Configuration section, each Bus
Terminal is mapped in the Bus Coupler. In the delivery state, this mapping
occurs with the default settings of the Bus Coupler for this terminal. The
default setting can be changed with the KS2000 configuration software or
with a master configuration software (e.g. TwinCAT System Manager or
ComProfibus).
If the terminals are fully evaluated, they occupy memory space in the input
and output process image.
The following tables provide information about the terminal mapping,
depending on the conditions set in the Bus Coupler.
