KL1501 - Terminal configuration
The terminal can be configured and parameterized via the internal register structure. Each terminal channel
is mapped in the Bus Coupler. Mapping of the terminal data in the Bus Coupler memory may differ,
depending on the Bus Coupler type and the set mapping configuration (e.g. Motorola/Intel format, word
alignment etc.).
In contrast to analog input and output terminals, in the KL1501 the control byte and the status byte
are
always
mapped, irrespective of the fieldbus system used.
BK2000 Lightbus Coupler
In the BK2000 Lightbus Coupler, the control/status byte is always mapped, in addition to the data bytes. This
is always located in the low byte at the offset address of the terminal channel.

BK3000 Profibus Coupler
In the BK3000 Profibus Coupler, the KL1501 is automatically mapped with 5 bytes of input data and 5 bytes
of output data.
