Beckhoff KL304 Series User Manual

Terminal configuration
6 KL304x and KL305x
Terminal configuration
The terminal can be configured and parameterized via the internal register
structure. Each terminal channel is mapped in the Bus Coupler. Depending
on the type of the Bus Coupler and the mapping configuration (e.g.
Motorola/Intel format, word alignment etc.) the terminal data are mapped in
different ways to the Bus Coupler memory. For parameterizing a terminal,
the control and status byte also has to be mapped.
BK2000 Lightbus Coupler In the BK2000 Lightbus coupler, the control and status byte is mapped in
addition to the data bytes. This is always located in the low byte at the
offset address of the terminal channel.
Example for KL3042 and KL3052:
0
Offset Terminal1 Channel1 = 0
Offset Terminal2 Channel1 = 4
KL3042
Offset Terminal2 Channel2 = 8

BK3000 Profibus coupler For the BK3000 Profibus coupler, the master configuration should specify
for which terminal channels the control and status byte is to be inserted. If
the control and status byte are not evaluated, the terminals occupy 2 bytes
per channel:
• KL3041 and KL3051: 2 bytes of input data
• KL3042 and KL3052: 4 bytes of input data
• KL3044 and KL3054: 8 bytes of input data
Example for KL3042 and KL3052:
Offset Terminal1 Channel1 = 0
Offset Terminal1 Channel2 = 3
Offset Terminal2 Channel1 = 6
KL 3042 Channel1
KL 3042 Channel 2
The control-/status byte
must be inserted for
parameterization.
