Terminal configuration
KL5051 7
Terminal configuration
The terminal can be configured and parametrized via the internal register
structure.
Each terminal channel is mapped in the bus coupler. The data of the termi-
nal is mapped differently in the memory of the bus coupler depending on
the type of the bus coupler and on the set mapping configuration (eg Moto-
rola/ intel format, word alignment,...). For parametrization of a terminal, the
control/status byte must als be mapped.
Beckhoff Lightbus
coupler BK2000 In the case of the Beckhoff Lightbus coupler BK2000, the control /status
byte is also always (ie in the case of all analog terminals) mapped in addi-
tion to the data bytes. It is always in the low byte at the offset address of
the terminal channel.
0 Offset Terminal1 Channel1 = 0
Offset Terminal2 Channel1 = 4

Profibus coupler BK3000 In the case of the Profibus coupler BK3000, the KL5051 is always mapped
with 6 bytes of input and 6 bytes of output data.
