8 KL4112
Interbus Coupler BK4000
By default, the Interbus coupler BK4000 maps the KL4112 with 4 bytes of
output data (2 bytes of user data per channel). Parametrization via the field
bus is not possible.The KS2000 software is needed for configuration if it is
intended to use the control / status byte.
Offset Terminal1 Channel1 = 0
Offset Terminal2 Channel1 = 4
Offset Terminal1 Channel2 = 2
Offset Terminal2 Channel1 = 6
The control/status byte
must be inserted for
parameterization (KS2000).

Note
The annex contains an overview of the possible mapping configurations
depending on the adjustable parameters.
Parametrization with
the KS2000 software Parametrization operations can be carried out independently of the field
bus system using the Beckhoff KS2000 configuration software via the seri-
al configuration interface in the bus coupler.
Register description
The complex terminals can be adjusted to different operating modes or
functionalities. The " general description of register " describes the con-
tents of the registers, which are identical for all complex terminals.
The terminal-specific registers are explained in the section following to it.
The access to the internal registers of the terminal is described in the sec-
tion " register communication ".
General register description
Complex terminals that possess a processor are capable of bidirectionally
ex-changing data with the higher-level control system. Below, these termi-
nals are referred to as intelligent bus terminals. They include the analog
inputs (0-10V, -10-10V, 0-20mA, 4-20mA), the analog outputs (0-10V, -10-
10V, 0-20mA, 4-20mA), serial interface terminals (RS485, RS232, TTY,
data transfer terminals), counter terminals, encoder interfaces, SSI inter-
faces, PWM terminals and all other parametrizable terminals.
Internally, all intelligent terminals possess a data structure that is identical
in terms of it's essential characteristics. This data area is organized in
