  • Page 24 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. Fig. 12: Mapping in the Lightbus coupler – example for KL4112 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.
  • Page 25 BK4000 Interbus Coupler The BK4000 Interbus Coupler maps the KL4112 in delivery state with 4 bytes of output data (2 bytes of user data per channel). Parameterization via the fieldbus is not possible. If the control and status byte is to be used, the KS2000 configuration software is required.
