5.1

The terminal can be configured and parameterized via the internal register structure. Each terminal channel

is mapped in the Bus Coupler. Mapping of the terminal data in the Bus Coupler memory may differ,

depending on the Bus Coupler type and the set mapping configuration (e.g. Motorola/Intel format, word

alignment etc.). For parameterizing a terminal, the control and status byte also has to be mapped.

BK2000 Lightbus Coupler

In the BK2000 Lightbus Coupler, the control/status byte is always mapped, in addition to the data bytes. This

is always located in the low byte at the offset address of the terminal channel.

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:

• KL4001: 2 bytes of output data

• KL4002: 4 bytes of output data

• KL4004: 8 bytes of output data

BK4000 Interbus Coupler

The BK4000 Interbus Coupler maps the terminals in the delivery state with 2 bytes per channel:
