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.
KL3102, KL3112, KL3122 7Version: 3.2
Foreword
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
(ANSIMH10.8.2-2016). 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.

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 without prior notice. No claims for changes can be made from the information, illustrations and descriptions in

Product Overview
2.4 KL3112, KL3122 - Introduction
Fig.3: KL3112, KL3122
Two-channel analog input terminals 0mA...20mA and 4mA...20mA
The analog input terminals process signals in the range of
• KL3112: 0mA ... 20mA
• KL3122: 4mA ... 20mA.
The current is digitized to a resolution of 16bits (default: 15bits), and is transmitted, in an electrically
isolated form, to the higher-level automation device. The input channels of the Bus Terminals have
differential inputs and possess a common, internal ground potential. The terminals combine two channels in
a single housing. A wire breakage or overload condition are detected, and the terminal state is relayed to the
controller via the K-bus. The Run LEDs indicate the data exchange with the Bus Coupler, while the Error
LEDs indicate overload.

Product Overview
2.6 Basic function principles
The analog input terminals process signals in the range of:
KL3102: -10V ... +10V
KL3112: 0mA ... 20mA
KL3122: 4mA ... 20mA
with a resolution of up to 16bits (65535 steps). The terminal inputs are differential inputs with common
ground. Due to the differential inputs, the terminals are particularly suitable for floating measuring of voltage
drops. In the standard version, a filter with a stop frequency (64.5dB) of 50Hz is active. The filter constant
and the associated conversion time are configurable in a wide range.
The green Run LEDs indicate the operating state of the associated terminal channel.
• On: Normal operation
• Off: Watchdog-timer overflow has occurred. If no process data are transmitted by the Bus Coupler for
100ms, the green LEDs go out.
The red ERROR LEDs indicate an overflow.
• On: Measured current outside the measuring range (> 20mA)
• Off: Current in valid range
KL3102 - Output format of the process data
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) [}38] (e.g.signed amount

Calculation of process data
The terminal continuously records measured values and stores the raw values of its A/D converter in register
R0 [}36] (RAM ). The calculation of the correction with the calibration values takes place after each
sampling of the analog signal. This is followed by manufacturer and user scaling:
The process data that are transferred to the Bus Coupler are calculated using the following equations:
KL3102, KL3112, KL312214 Version: 3.2
Product Overview
Y_a = (B_a + X_adc) * A_a
Y_aus = Y_a
Y_1 = B_h + A_h * Y_a
Y_aus = Y_1
Y_2 = B_w + A_w * Y_a
Y_aus = Y_2
Y_1 = B_h + A_h * Y_a

3.1 Instructions for ESD protection
NOTE
Destruction of the devices by electrostatic discharge possible!
The devices contain components at risk from electrostatic discharge caused by improper handling.
• Please ensure you are electrostatically discharged and avoid touching the contacts of the device directly.
• Avoid contact with highly insulating materials (synthetic fibers, plastic film etc.).
• Surroundings (working place, packaging and personnel) should by grounded probably, when handling
with the devices.
• Each assembly must be terminated at the right hand end with a KL9010 bus end terminal, to ensure the
protection class and ESD protection.

3.2 Installation on mounting rails
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or
wiring of the bus terminals!
KL3102, KL3112, KL312216 Version: 3.2
Assembly
Mounting and wiring
Fig.6: Attaching on mounting rail
The bus coupler and bus terminals are attached to commercially available 35mm mounting rails (DIN rails
according to EN60715) by applying slight pressure:
1. First attach the fieldbus coupler to the mounting rail.
2. The bus terminals are now attached on the right-hand side of the fieldbus coupler. Join the components with tongue and groove and push the terminals against the mounting rail, until the lock clicks
onto the mounting rail.
If the terminals are clipped onto the mounting rail first and then pushed together without tongue and
groove, the connection will not be operational! When correctly assembled, no significant gap should
be visible between the housings.
Fixing of mounting rails
The locking mechanism of the terminals and couplers extends to the profile of the mounting rail. At
the installation, the locking mechanism of the components must not come into conflict with the fixing
bolts of the mounting rail. To mount the mounting rails with a height of 7.5mm under the terminals
and couplers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).
KL3102, KL3112, KL3122 17Version: 3.2
Mounting and wiring
Disassembly
Fig.7: Disassembling of terminal
Each terminal is secured by a lock on the mounting rail, which must be released for disassembly:
1. Pull the terminal by its orange-colored lugs approximately 1cm away from the mounting rail. In doing
so for this terminal the mounting rail lock is released automatically and you can pull the terminal out of
the bus terminal block easily without excessive force.
2. Grasp the released terminal with thumb and index finger simultaneous at the upper and lower grooved
housing surfaces and pull the terminal out of the bus terminal block.
Connections within a bus terminal block
The electric connections between the Bus Coupler and the Bus Terminals are automatically realized by
joining the components:
• The six spring contacts of the K-Bus/E-Bus deal with the transfer of the data and the supply of the Bus
Terminal electronics.
• The power contacts deal with the supply for the field electronics and thus represent a supply rail within
the bus terminal block. The power contacts are supplied via terminals on the Bus Coupler (up to 24V)
or for higher voltages via power feed terminals.
Power Contacts
During the design of a bus terminal block, the pin assignment of the individual Bus Terminals must
be taken account of, since some types (e.g. analog Bus Terminals or digital 4-channel Bus Terminals) do not or not fully loop through the power contacts. Power Feed Terminals (KL91xx, KL92xx
or EL91xx, EL92xx) interrupt the power contacts and thus represent the start of a new supply rail.
PE power contact
The power contact labeled PE can be used as a protective earth. For safety reasons this contact mates first
when plugging together, and can ground short-circuit currents of up to 125A.
KL3102, KL3112, KL312218 Version: 3.2
Fig.8: Power contact on left side
Mounting and wiring
NOTE
Possible damage of the device
Note that, for reasons of electromagnetic compatibility, the PE contacts are capacitatively coupled to the
mounting rail. This may lead to incorrect results during insulation testing or to damage on the terminal (e.g.
disruptive discharge to the PE line during insulation testing of a consumer with a nominal voltage of 230V).
For insulation testing, disconnect the PE supply line at the Bus Coupler or the Power Feed Terminal! In order to decouple further feed points for testing, these Power Feed Terminals can be released and pulled at
least 10mm from the group of terminals.
WARNING
Risk of electric shock!
The PE power contact must not be used for other potentials!

3.3 Installation instructions for enhanced mechanical load capacity
WARNING
Risk of injury through electric shock and damage to the device!
Bring the Bus Terminal system into a safe, de-energized state before starting mounting, disassembly or
wiring of the Bus Terminals!
Additional checks
The terminals have undergone the following additional tests:
Verification Explanation

60.1Hz<f<500Hz acceleration 5g, constant amplitude
Shocks 1000 shocks in each direction, in 3 axes
25 g, 6 ms
Additional installation instructions
For terminals with enhanced mechanical load capacity, the following additional installation instructions apply:
• The enhanced mechanical load capacity is valid for all permissible installation positions
• Use a mounting rail according to EN 60715 TH35-15
• Fix the terminal segment on both sides of the mounting rail with a mechanical fixture, e.g. an earth
terminal or reinforced end clamp
• The maximum total extension of the terminal segment (without coupler) is:
64 terminals (12 mm mounting with) or 32 terminals (24 mm mounting with)
• Avoid deformation, twisting, crushing and bending of the mounting rail during edging and installation of
the rail
• The mounting points of the mounting rail must be set at 5 cm intervals
• Use countersunk head screws to fasten the mounting rail
• The free length between the strain relief and the wire connection should be kept as short as possible. A
distance of approx. 10 cm should be maintained to the cable duct.

Overview
The Bus Terminal system offers different connection options for optimum adaptation to the respective
application:
• The terminals of ELxxxx and KLxxxx series with standard wiring include electronics and connection
level in a single enclosure.
KL3102, KL3112, KL312220 Version: 3.2
Mounting and wiring
• The terminals of ESxxxx and KSxxxx series feature a pluggable connection level and enable steady
wiring while replacing.
• The High Density Terminals (HD Terminals) include electronics and connection level in a single
enclosure and have advanced packaging density.
Standard wiring (ELxxxx / KLxxxx)
Fig.9: Standard wiring
The terminals of ELxxxx and KLxxxx series have been tried and tested for years.
They feature integrated screwless spring force technology for fast and simple assembly.
Pluggable wiring (ESxxxx / KSxxxx)
Fig.10: Pluggable wiring
The terminals of ESxxxx and KSxxxx series feature a pluggable connection level.
The assembly and wiring procedure is the same as for the ELxxxx and KLxxxx series.
The pluggable connection level enables the complete wiring to be removed as a plug connector from the top
of the housing for servicing.
The lower section can be removed from the terminal block by pulling the unlocking tab.
Insert the new component and plug in the connector with the wiring. This reduces the installation time and
eliminates the risk of wires being mixed up.
The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3
mm. The maximum height of the terminal remains unchanged.
A tab for strain relief of the cable simplifies assembly in many applications and prevents tangling of individual
connection wires when the connector is removed.
Conductor cross sections between 0.08mm2 and 2.5mm2 can continue to be used with the proven spring
force technology.
The overview and nomenclature of the product names for ESxxxx and KSxxxx series has been retained as
known from ELxxxx and KLxxxx series.

High Density Terminals (HD Terminals)
Fig.11: High Density Terminals
The Bus Terminals from these series with 16 terminal points are distinguished by a particularly compact
design, as the packaging density is twice as large as that of the standard 12mm Bus Terminals. Massive
conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal
point without tools.
Wiring HD Terminals
The High Density (HD) Terminals of the ELx8xx and KLx8xx series doesn't support pluggable
wiring.
Ultrasonically "bonded" (ultrasonically welded) conductors
Ultrasonically “bonded" conductors

Fig.12: Connecting a cable on a terminal point
Up to eight terminal points enable the connection of solid or finely stranded cables to the Bus Terminal. The
terminal points are implemented in spring force technology. Connect the cables as follows:
1. Open a terminal point by pushing a screwdriver straight against the stop into the square opening
above the terminal point. Do not turn the screwdriver or move it alternately (don't toggle).
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal point closes automatically when the pressure is released, holding the wire securely and
permanently.

4 Configuration Software KS2000
4.1 KS2000 - Introduction
The KS2000 configuration software permits configuration, commissioning and parameterization of bus
couplers, of the affiliated bus terminals and of Fieldbus Box Modules. The connection between bus coupler/
Fieldbus Box Module and the PC is established by means of the serial configuration cable or the fieldbus.
Fig.15: KS2000 configuration software
Configuration
You can configure the Fieldbus stations with the Configuration Software KS2000 offline. That means, setting
up a terminal station with all settings on the couplers and terminals resp. the Fieldbus Box Modules can be
prepared before the commissioning phase. Later on, this configuration can be transferred to the terminal
station in the commissioning phase by means of a download. For documentation purposes, you are provided
with the breakdown of the terminal station, a parts list of modules used and a list of the parameters you have
modified. After an upload, existing fieldbus stations are at your disposal for further editing.
Parameterization
KS2000 offers simple access to the parameters of a fieldbus station: specific high-level dialogs are available
for all bus couplers, all intelligent bus terminals and Fieldbus Box modules with the aid of which settings can
be modified easily. Alternatively, you have full access to all internal registers of the bus couplers and
intelligent terminals. Refer to the register description for the meanings of the registers.
KL3102, KL3112, KL3122 29Version: 3.2
Configuration Software KS2000
Commissioning
The KS2000 software facilitates commissioning of machine components or their fieldbus stations: Configured
settings can be transferred to the fieldbus modules by means of a download. After a login to the terminal
station, it is possible to define settings in couplers, terminals and Fieldbus Box modules directly online. The
same high-level dialogs and register access are available for this purpose as in the configuration phase.
The KS2000 offers access to the process images of the bus couplers and Fieldbus Box modules.
• Thus, the coupler's input and output images can be observed by monitoring.
• Process values can be specified in the output image for commissioning of the output modules.
All possibilities in the online mode can be used in parallel with the actual fieldbus mode of the terminal
station. The fieldbus protocol always has the higher priority in this case.

5.1 Terminal configuration
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.
Fig.19: Mapping in the Lightbus Coupler - Example for KL3102, KL3112, KL3122
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 4bytes of input data (2 bytes per channel).
Fig.20: Mapping in the Profibus Coupler - Example for KL3102, KL3112, KL3122
BK4000 Interbus Coupler
In delivery state the BK4000 Interbus Coupler maps the terminals with 4 bytes of input data (2bytes 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.

Access from the user program
Fig.21: Mapping in the Interbus Coupler - Example for KL3102, KL3112, KL3122
Other Bus Couplers and further information
Further information about the mapping configuration of Bus Couplers can be found in the Appendix of the
respective Bus Coupler manual under Master configuration.
The chapter on Mapping in the Bus Coupler [}34] contains an overview of possible mapping
configurations, depending on the configurable parameters.
Parameterization with KS2000
The KS2000 configuration software can be used for parameterizations via the serial interface of the
Bus Coupler, independent of the fieldbus system.
5.2 Mapping in the Bus Coupler
As already described in the Terminal Configuration chapter, each Bus Terminal is mapped in the Bus
Coupler. This mapping is usually done with the default setting in the Bus Coupler / Bus Terminal. The
KS2000 configuration software or a master configuration software (e.g.ComProfibus or TwinCAT System
Manager) can be used to change this default setting.
If the terminals are fully evaluated, they occupy memory space in the input and output process image.
The following tables provide information about how the terminals map themselves in the Bus Coupler,
depending on the parameters set.

Access from the user program
R8 to R15: Registers in the internal ROM of the terminal
The type and system parameters are hard programmed by the manufacturer, and the user can read them
but cannot change them.
• R8: Terminal type
The terminal type in register R8 is needed to identify the terminal.
• R9: Software version (X.y)
The software version can be read as a string of ASCII characters.
• R10: Data length
R10 contains the number of multiplexed shift registers and their length in bits.
The Bus Coupler sees this structure.
• R11: Signal channels
Related to R10, this contains the number of channels that are logically present. Thus for example a
shift register that is physically present can perfectly well consist of several signal channels.
• R12: Minimum data length
The particular byte contains the minimum data length for a channel that is to be transferred. If the MSB
is set, the control and status byte is not necessarily required for the terminal function and is not
transferred to the control, if the Bus Coupler is configured accordingly.

• R14: reserved
• R15: Alignment bits (RAM)
The alignment bits are used to place the analog terminal in the Bus Coupler on a byte boundary.
R16 to R30: Manufacturer parameter area (SEEROM)
The manufacturer parameters are specific for each type of terminal. They are programmed by the
manufacturer, but can also be modified by the controller. The manufacturer parameters are stored in a serial
EEPROM in the terminal, and are retained in the event of voltage drop-out.
These registers can only be altered after a code word has been set in R31 [}38].
• R17: Hardware compensation - offset (B_a)
KL3102: [approx. 0x00XX], KL3112 & KL3122 [0xFBxx]
16bit signed integer*2^-16+1
This register is used for offset compensation of the terminal (Eq. 1.1 [}14]).

This register is used for gain compensation of the terminal (Eq. 1.1 [}14]).
1 corresponds to 0x0000, 2 corresponds to 0xFFFF
• R19: Manufacturer scaling - offset (B_h)
16bit signed integer [0x0000]
This register contains the offset of the manufacturer straight-line equation (equation 1.3 [}14]). The
straight-line equation is enabled via register R32.
• R20: Manufacturer scaling - gain (A_h)
KL3102: [0x0100], KL3112 and KL3122: [0x0000]
16bit signed integer*2-8
This register contains the scale factor of the manufacturer's equation of the straight line (Eq. 1.3 [}14]).
The straight-line equation is enabled via register R32.
1 corresponds to register value 0x0400.
R31 to R47: User parameter area (SEEROM)
The user parameters are specific for each type of terminal. They can be modified by the programmer. The
user parameters are stored in a serial EEPROM in the terminal, and are retained in the event of voltage
drop-out. The user area is write-protected by a code word.
• R31: Code word register in RAM
The code word 0x1235 must be entered here so that parameters in the user area can be modified.
If any other value is entered into this register, the write-protection is active. When write protection is
not active, the code word is returned when the register is read. If the write protection is active, the
register contains a zero value.
• R32: Feature register
KL3102: [0x1106], KL3112 and KL3122[0x0002]
This register specifies the operation modes of the terminal. Thus, forinstance, a user-specific scaling
can be enabled for the analog I/Os.
Value range of KL3112 and KL3122
For reasons of compatibility, 16bits signed integer is selected as the (standard) output format. The
positive value range for 0mA / 4mA to 20mA therefore extends from 0 to 32767 (0x7FFF). This
corresponds to 15bits. Manufacturer scaling must be disabled in order to exploit all 16bits of the
terminal.

5.5 Control and status byte
The control and status byte is transmitted from the controller to the terminal. It can be used
• in register mode [}42] (REG = 1
• in process data exchange [}41] (REG = 0
) or
bin
).
bin
5.5.1 Process data exchange
Control byte in process data exchange (REG=0)
A gain and offset calibration of the terminal can be carried out with the control byte. The code word must be
entered in R31 [}38] so that the terminal calibration can be carried out. The gain and offset of the terminal
can then be calibrated. The parameter will only be saved permanently once the code word is reset!

5.5.2 Register communication
Register access via process data exchange
• Bit 7=1: Register mode
If bit 7 of the control byte is set, the first two bytes of the user data are not used for process data
exchange but written into the register set of the terminal or read from it.
• Bit 6=0: read, bit 6=1: write
Bit 6 of the control bytes is used to specify whether a register should be read or written.
◦ Bit 6=0: a register is read without changing it. The value can be found in the input process image.
◦ Bit 6=1: the user data are written to a register. The process is complete once the status byte in the
input process image has returned an acknowledgment (see example).
• Bit 0to 5: Address
The address of the register to be addressed is entered in bits 0 to 5 of the control byte.

Fig.22: Register mode control byte
The control or status byte occupies the lowest address of a logical channel. The corresponding register
values are located in the following 2 data bytes. (The BK2000 is an exception: here, an unused data byte is
inserted after the control or status byte, and the register value is therefore placed on a word boundary).
Example 1:
Reading of register 8 in the BK2000 with a KL3102 and the end terminal:
If the following bytes are transferred from the controller to the terminal,

Access from the user program
Byte Byte 3 Byte 2 Byte 1 Byte 0
Name DataOUT 1 DataOUT 0 Not used Control byte
Value 0xXX 0xXX 0xXX 0x88
The terminal returns the following type identifier (0x0C1E corresponds to unsigned integer 3102)
Byte Byte 3 Byte 2 Byte 1 Byte 0
Name DataIN 1 DataIN 0 Not used Status byte
Value 0x1E 0x0C 0x00 0x88
Example 2:
Write register 31 in the BK2000 with a KL3102 and the end terminal:
If the following bytes (code word [}38]) are transferred from the controller to the terminal,
Byte Byte 3 Byte 2 Byte 1 Byte 0
Name DataOUT 1 DataOUT 0 Not used Control byte
Value 0x12 0x35 0xXX 0xDF
The code word [}38] is set, and the terminal returns the register address with bit7 for register access as
acknowledgment.

Value 0x00 0x00 0x00 0x9F
5.6 Examples of Register Communication
The numbering of the bytes in the examples corresponds to the display without word alignment.
5.6.1 Example 1: reading the firmware version from Register 9
Output Data
Byte 0: Control byte Byte 1: DataOUT1, high byte Byte 2: DataOUT1, low byte
0x89 (1000 1001
Explanation:
• Bit 0.7 set means: Register communication switched on.
• Bit 0.6 not set means: reading the register.
• Bits 0.5 to 0.0 specify the register number 9 with 00 1001
• The output data word (byte 1 and byte 2) has no meaning during read access. To change a register,
write the required value into the output word.

.
bin
Input Data (answer of the bus terminal)
Byte 0: Status byte Byte 1: DataIN1, high byte Byte 2: DataIN1, low byte
0x89 0x33 0x41
Explanation:
• The terminal returns the value of the control byte as a receipt in the status byte.
• The terminal returns the firmware version 0x3341 in the input data word (byte 1 and byte 2). This is to
be interpreted as an ASCII code:
◦ ASCII code 0x33 represents the digit 3
KL3102, KL3112, KL3122 43Version: 3.2
Access from the user program
◦ ASCII code 0x41 represents the letter A
The firmware version is thus 3A.
5.6.2 Example 2: Writing to an user register
Code word
In normal mode all user registers are read-only with the exception of Register 31. In order to deactivate this write protection you must write the code word (0x1235) into Register 31. If a value other
than 0x1235 is written into Register 31, write protection is reactivated. Please note that changes to
a register only become effective after restarting the terminal (power-off/power-on).
I. Write the code word (0x1235) into Register 31.
Output Data
Byte 0: Control byte Byte 1: DataOUT1, high byte Byte 2: DataOUT1, low byte
0xDF (1101 1111
Explanation:
• Bit 0.7 set means: Register communication switched on.
• Bit 0.6 set means: writing to the register.
• Bits 0.5 to 0.0 specify the register number 31 with 01 1111
• The output data word (byte 1 and byte 2) contains the code word (0x1235) for deactivating write
protection.
