KL3201, KL3202 and KL3204

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 KL3202:

Offset Terminal1 Channel1 = 0

Offset Terminal2 Channel1 = 4
KL3202

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:

• KL3201: 2 bytes of input data

• KL3202: 4 bytes of input data

• KL3204: 8 bytes of input data

Example for KL3202:

Offset Terminal1 Channel1 = 0

Offset Terminal1 Channel2 = 3

Offset Terminal2 Channel1 = 6

KL 3202 Channel1

KL 3202 Channel 2

The control-/status byte

must be inserted for

parameterization.
