1.4 Beckhoff Identification Code (BIC)
The Beckhoff Identification Code (BIC) is increasingly being applied to Beckhoff products to uniquely identify
the product. The BIC is represented as a Data Matrix Code (DMC, code scheme ECC200), the content is
based on the ANSI standard MH10.8.2-2016.
Fig.1: BIC as data matrix code (DMC, code scheme ECC200)
The BIC will be introduced step by step across all product groups.
Depending on the product, it can be found in the following places:
on the packaging unit
directly on the product (if space suffices)
on the packaging unit and the product
The BIC is machine-readable and contains information that can also be used by the customer for handling
and product management.
Each piece of information can be uniquely identified using the so-called data identifier
(ANSIMH10.8.2-2016). The data identifier is followed by a character string. Both together have a maximum
length according to the table below. If the information is shorter, spaces are added to it. The data under
positions 1 to 4 are always available.
The following information is contained:

Further types of information and data identifiers are used by Beckhoff and serve internal processes.
Structure of the BIC
Example of composite information from item 1 to 4 and 6. The data identifiers are marked in red for better
display:
BTN
An important component of the BIC is the Beckhoff Traceability Number (BTN, item no.2). The BTN is a
unique serial number consisting of eight characters that will replace all other serial number systems at
Beckhoff in the long term (e.g. batch designations on IO components, previous serial number range for
safety products, etc.). The BTN will also be introduced step by step, so it may happen that the BTN is not yet
coded in the BIC.
NOTE
This information has been carefully prepared. However, the procedure described is constantly being further
developed. We reserve the right to revise and change procedures and documentation at any time and with-
out prior notice. No claims for changes can be made from the information, illustrations and descriptions in
this information.

2.1 Introduction
KL3444: 4-channel analog input terminal 0 ... 20mA
Fig.2: KL3444
The EL3444 analog input terminal process signals in the range between 0 and 20mA. The current is
digitized to a resolution of 12bits, and is transmitted, in an electrically isolated form, to the higher-level
automation device.
In the KL3444 Bus Terminal, the four inputs are 2-wire versions and have a common ground potential. This
reference ground of the inputs is electrically isolated from the 0V power contact. The power contacts are
connected through.
Overload is detected and the terminal status is forwarded to the controller via the K-bus. The Run LEDs
indicate the data exchange with the Bus Coupler, while the Error LEDs indicate overload.

In the KL3454 Bus Terminal, the four inputs are 2-wire versions and have a common ground potential. This
reference ground of the inputs is connected to the 0V power contact. The 24V power contact is connected
to the terminals, in order to enable the connection of 2-wire sensors without external supply. The power
contacts are connected through.
Overload is detected and the terminal status is forwarded to the controller via the K-bus. The Run LEDs
indicate the data exchange with the Bus Coupler, while the Error LEDs indicate overload.

4 Basic Function Principles
The analog input terminals
KL3444 and KL3448 process signals in the range between 0 and 20mA
KL3454 and KL3458 process signals in the range between 4 and 20mA
with a resolution of 12bits (4095 steps). They can supply the sensors from voltage fed in via the power
contacts. The power contacts can optionally be supplied via the standard supply or via a power feed terminal
with electrical isolation.
Process data output format
In the delivery state the process data are shown in two's complement form (integer -1 corresponds to
0xFFFF). Other presentation types can be selected via the feature register R32 (e.g. signed amount
representation, Siemens output format).
