BECKHOFF KL5101-0000 - Manual (Page 18)

Terminal configuration
16 KL5101
3.5.1 Examples
Each terminal channel is mapped in the bus coupler. The data of the
terminal is mapped differently in the memory of the bus coupler depending
on the type of the bus coupler and on the set mapping configuration (e.g.
Motorola/ Intel format, word alignment,...). Contrary to the analog input and
output terminals, in the case of the KL5101 the control and status byte is
always mapped regardless of the higher-level field bus system.
Lightbus coupler BK2000 In the case of the Beckhoff Lightbus coupler BK2000, the control /status
byte is also always (i.e. in the case of all analog terminals) mapped in
addition to the data bytes. It is always in the low byte at the offset address
of the terminal channel.

BK3000 In the case of the PROFIBUS coupler BK3000, the KL5101 is always
mapped with 6 bytes of input data and 6 bytes of output data.
