Terminal configuration
The terminal can be configured and parametrized by way of the internal
register structure.
Each terminal channel is mapped in the bus coupler. The terminal’s data is
mapped differently in the bus coupler’s memory depending on the type of
the bus coupler and on the set mapping configuration (eg.Motorola / Intel
format, word alignment,...). For parametrization of a terminal, the control
/status byte must also be mapped.
Beckhoff Lightbus
Coupler BK2000 In the case of the Beckhoff Lightbus coupler BK2000, the control /status
byte is always mapped besides the data bytes. It is always in the low byte
at the offset address of the terminal channel.

Profibus Coupler BK3000 In the case of the Profibus coupler BK3000, for which terminal channels
the control /status byte is also to be inserted must be defined in the master
configuration .If the control /status byte is not evaluated, the KL3064 occu-
pies 8 bytes of input data (2 bytes of user data per channel).
