The devices from the MA 2xxi family feature four M 12 connectors/sockets which are coded
differently depending on the interface.
Fast commissioning / operating principle
3.3.1
Connecting the Leuze device
 To connect the Leuze device to the internal RS 232 device interface, open the housing
of the MA 204i and guide the corresponding device cable (see chapter 14.7, e.g., KB 031
for BCL 32) through the middle threaded opening.
 Connect the cable to the internal device interface (X30, X31 or X32, see chapter 7.5.1).
 Use rotary switch S4 (see chapter 8.2.5) to select the connected device.
 Now screw the PG cable gland into the threaded opening to provide strain relief and
ensure protection class IP 65.
3.3.2
Setting the PROFIBUS device address
 Set the station address of the gateway via the rotary switch S1 - S3 (ones, tens and
hundreds digits).
Notice!
The PROFIBUS permits an address range from 0 to 126. Address 126 must not be used for
data communication. It may only be used temporarily for commissioning. Make certain that
you assign each PROFIBUS participant a different PROFIBUS address.
Hundreds

Rotary switch for setting the address
 Finally, close the housing of the MA 204i.
Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 204i, the device selection switch and the address settings are
queried and the gateway automatically sets itself to the Leuze device.
Connecting functional earth FE
 Ensure that the functional earth (FE) is connected correctly.
12
MA 204i
Leuze electronic
Fast commissioning / operating principle
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth
connection.
3.3.3
Connecting the power supply and the bus cable
 Ideally, use the ready-made cables listed in chapter 14.5.3 to connect the gateway to the
power supply via the PWR IN connection.
 For the connection of the gateway to the fieldbus via the HOST / BUS IN connection,
the ready-made cables listed in are preferred.
 If applicable, use the BUS OUT connection if you would like to construct a network with
linear topology.
3.4
Starting the device
 Apply the supply voltage +18 … 30 V DC (+24 V DC model).
The MA 204i starts up; the PWR LED displays that it is ready for operation.
3.5
Commissioning the MA 204i on the PROFIBUS DP
 Complete the necessary steps for commissioning a Siemens-S7 control as described
below.
3.5.1
Preparing the control system
 In the first step, prepare the control for consistent data transmission.
During programming the control system must be prepared for consistent data transmission.
This varies from control system to control system. The following possibilities are available
for the Siemens control systems.
S7
The specific function blocks SFC 14 for input data and SFC 15 for output data must be
integrated in the program. These are standard function blocks and are used to facilitate
consistent data transmission.
Notice!
If an S7 control is used, you need to ensure that Simatic-Manager Version 5.4 +
service pack 5 (V5.4+SP5) or higher is used.

Further information regarding the individual commissioning steps is provided in see chapter
12.3 "Configuration steps for a Siemens Simatic S7 control".
Fast commissioning / operating principle
3.5.2
Installation of the GSD file
For the subsequent configuration of the PROFIBUS devices, e.g., MA 204i, the
corresponding GSD file must be loaded first. All data in modules required for operating the
device is described in this file. These are input and output data and device parameters for
the functioning of the device and the definition of the control and status bits.
 Install the GSD file associated with the device in the PROFIBUS Manager of your control.
3.5.3
Configuration
 Configure the PROFIBUS system using the HW Config of the SIMATIC Manager by
inserting the MA 204i into your project and assigning it a unique address (0 … 125).
Notice!
Ensure that the address is the same as the address configured in the device.
Figure 3.3:
14
Assignment of the device address
MA 204i
Leuze electronic
Fast commissioning / operating principle
3.5.4
Configuration of the modules
 Now select a corresponding data module for the input and output area.
A number of combinable modules are available with various data lengths (4, 8, 12, 16, 20,
32 … 128 bytes). In total, a maximum of 244 bytes are possible for both the input bytes and
for the output bytes.
Notice!
Because the data module contains 2 bytes for the control and status bytes, the actual user
data length is always 2 bytes smaller than the selected data module.
E.g., when using the data module with 12 bytes, there are effectively 10 bytes available for
user data on the Leuze device after subtracting the 2 bytes for status and control bytes.
Recommendation
In most cases, the 4-byte module is sufficient for the output module.
A larger module is needed, for example, if a BCL bar code scanner is to be configured by
means of PT-sequences, or an RFID transponder is to be described. In these cases, larger
data modules are usually sensible.
Notice!
Examples for selecting the correct data module length can be found in chapter 12.3.4,
section "Examples of sensible settings for corresponding Leuze devices" on page 63.
3.5.5
Transmission of the configuration to the controller
After correct transmission to the controller (S7 PLC), the PLC automatically carries out the
following activities:
• Establishment of a connection between the controller and configured
PROFIBUS devices
• Cyclical data exchange

General Information to the connector units
The modular interfacing unit of the MA 2xxi family is a versatile gateway for integrating Leuze
RS 232 devices (e.g., BCL 22 bar code readers, RFID devices, RFM 32, AMS 200) in the
respective fieldbus. The MA 2xxi gateways are intended for use in industrial environments
with a high protection class. Various device versions are available for the conventional
fieldbuses. With a stored parameter structure for the connectable RS 232 devices,
commissioning could hardly be simpler.
4.2
Characteristics of the connector units
A special characteristic of the MA 204i device family are three function modes:
16
1.
Transparent mode
In this function mode, the MA 204i functions as a pure gateway with automatic
communication from and to the PLC. Absolutely no special programming by the user
is necessary for this purpose. The data is not buffered or stored temporarily, however.
Instead, it is "passed on".
The programmer must make certain to retrieve the data from the input memory of the
PLC at the right time, as it is otherwise overwritten by new data.
2.
Collective mode
In this operating mode, data and telegram parts are temporarily stored in the memory
(buffer) of the MA and sent to the RS 232 interface or to the PLC in a telegram by means
of bit activation. In this mode, however, all communication control must be
programmed on the PLC.
This function mode is helpful, for example, for very long telegrams or when one or
more codes with long code lengths are read.
3.
Command mode
With this special operating mode, it is possible to use the first bytes of the data range
to transmit predefined commands to the connected device by means of bit activation.
For this purpose, device-dependent commands (so-called online commands) are
predefined via the device selection switch, see chapter 16 "Specifications for Leuze
end devices".

The MA 204i modular interfacing unit is used for interconnecting Leuze devices, such as
the BCL 8, BCL 22, etc., directly to the fieldbus. This is accomplished by transmitting the
data from the Leuze device via an RS 232 (V.24) interface to the MA 204i where a module
converts it into the fieldbus format. The data format of the RS 232 interface corresponds to
the standard Leuze data format.

Connection of a Leuze devices (BCL, RFI, RFM, VR) to the fieldbus
The cable of the respective Leuze device is guided through cable bushings with PG cable
glands into the MA 204i and connected there with the PCB connectors.
The MA 204i is intended as a gateway for any RS 232 devices, e.g., BCL 90 with MA 90,
hand-held scanners, scales or for coupling a multiNet network.
The RS 232 cables are internally connectable using JST plug connectors. The cable can be
connected to the device using a stable PG cable gland which provide strain relief and
protection against contamination.
With the help of adapter cables with Sub-D 9 or open cable end, other RS 232 devices can
also be connected.

Operating modes
For fast commissioning, the MA 204i offers an additional operating mode, the "Service
mode", in addition to the "Standard mode". In this operating mode, the Leuze device can,
for example, be configured on the MA 204i and the communication can be tested on the
fieldbus. To do this, you need a PC/laptop with a suitable terminal program, as BCL-Config
from Leuze or similar.
Service switch
Select between "operation" and "service" modes with the service switch. You have the
following options:
Pos. RUN:
Operation
The Leuze device is connected to the fieldbus and communicates with the PLC.
Pos. DEV:
Service Leuze device
The connection between the Leuze device and the fieldbus is interrupted. With this
switch position, you can communicate directly with the Leuze device at the fieldbus
gateway via RS 232. You can send online commands via the service interface,
configure the Leuze device using the corresponding BCL- BPS-, …-Config
configuration software and have the read data of the Leuze device output.
Pos. MA:
Service fieldbus gateway
With this switch setting, your PC/terminal is connected with the fieldbus gateway. In
doing so, the current setting values of the MA (e.g. address, RS 232 parameters) can
be called up via a command.

Service-switch switch positions
Notice!
If the service switch is on one of the service settings, the PWR LED flashes on the front side
of the device, see chapter 8.1.2 "LED indicators on the housing".
Furthermore, on the control, the SMA service bit of the status bytes signals that the MA is
in service mode.

The gateway is set via the switch position on the Leuze device. If the switch position is
changed, the device must be restarted, since the switch position is only queried after
switching off completely and then restarting the device.
Note!
In switch position "0", a distance of >20 ms must be maintained between two telegrams so
they can be distinguished from one another.
The parameters of the Leuze end devices are described in chapter 16.
Additional parameters such as the baud rate and data mode can be configured via the GSD
file with the "USE GSD settings" enable function. The data frame and, if necessary, the length
are specified via the switch position.

Structure of the fieldbus telegram
All operations are performed by control and status bits. Two bytes of control information
and two bytes of status information are available for this purpose. The control bits are a part
of the output module and the status bits are a part of the input bytes. The data starts with
the third byte.
If the actual data length is longer than the data length configured in the gateway, only part
of the data is transmitted; the remaining data is lost. In this case, the DL (data loss) bit is set.
The following telegram structure is used between PLC -> fieldbus gateway:

Modes

Modes
11.1
Functionality of the data exchange
The fieldbus gateway has two different modes that can be selected via the PLC:
• Transparent mode (default setting)
In Transparent mode, all data are sent 1:1 and directly by the serial end device to the
PLC. It is not necessary to use status and control bits here. However, only data bytes
possible for one transmission cycle are transmitted - all others are lost.
The distance between two successive telegrams (without frame) must be more than
20 ms, since there is otherwise no clear separation between them.
ASCII characters are typically expected as data content; under certain circumstances,
the MA therefore detects different control characters as invalid characters in the data
range and truncates them. At 00h in the data range, the MA cuts the telegram off
because unnecessary bytes are also filled with 00h .
• Collective mode
In Collective mode, the data of the serial end device is stored temporarily in the fieldbus
gateway by toggling the CTB bit and is not sent to the PLC in blocks until prompted
to do so by the PLC.
On the PLC, a status bit (DEX) then signals that new data is ready for retrieval. This
data is then read out from the fieldbus gateway in blocks (toggle bit).
In order to distinguish between the individual telegrams on the PLC, in Collective mode
the serial frame is sent to the PLC in addition to the data.
The size of the buffer is 1 kByte.
Notice!
In Collective mode, the CTB and SFB bits are needed for communication handling via the
buffer. Telegrams that can also be completely transmitted in one cycle in Collective mode
(including data frame) go directly through. If PLC data is provided and transferred without a
state change of the CTB bit, it goes directly to the RS 232 interface with the set telegram
data length. Incomplete (incl. data frame) or faulty telegrams can cause error messages in
the connected device!
Combination with the Command mode is possible.
Data exchange in blocks must be programmed on the PLC.
11.1.1
Reading slave data in Collective mode (gateway -> PLC)
If the Leuze device transmits data to the fieldbus gateway, the data is stored temporarily in
a buffer. The PLC is signaled via the "DEX" bit that data is ready for retrieval in the memory.
Data is not automatically transmitted.
If no further user data is present in the MA 2xxi ("DEX" bit = "0"), the "R-ACK" bit must be
toggled once as read confirmation to release data transmission for the next read cycle.
52
MA 204i
Leuze electronic
Modes
If the buffer still contains more data ("DEX bit = 1), the next remaining user data present in
the buffer is transmitted by toggling the "R-ACK" control bit. This process is to be repeated
until the "DEX" bit returns to "0"; all data has then been removed from the buffer. "R-ACK"
must be toggled here again once more as a terminating read confirmation in order to release
data transmission for the next read cycle.

R-ACK
Writing slave data in Collective mode (PLC -> gateway)Writing in blocks
The data sent by the master to the slave is first collected in a "transmit buffer" by setting
the "CTB" bit (Copy to transmit buffer). Please observe that data provided is transmitted
directly by toggling the bit.
The data is then sent in the order received from the buffer to the connected Leuze device
via the serial interface with the command: "SFB" (Send data from transmit buffer). Please
don't forget the suitable data frame!
Afterward, the buffer is again empty and can be written with new data.
With this function, it is possible to temporarily store longer data strings in the gateway
independent of how many bytes the used fieldbus can transmit at once. With this function,
longer PT sequences or RFID write sequences, for example, can be transmitted, since the
connected devices can, in this way, receive their commands (e.g., PT or W) in a continuous
string. The respective frame (STX CR LF) is needed to differentiate between the individual
telegrams.
Used status and control bits:
• CTB
• SFB
11.1.2 W-ACK
If PLC data is provided and transferred without a state change of the CTB bit, it goes directly
to the RS 232 interface with the set telegram data length. Incomplete (incl. data frame) or
faulty telegrams can cause error messages in the connected device!
Examples for the activation of a Leuze device
In the data part (starting at byte 2) of the telegram to the gateway, a "+" (ASCII) is sent for
activation.

Command mode
One specific feature is the so-called Command mode, which is defined via the output control
byte 0 (bit 0)... and enables the control of the connected device per bit.
If the Command mode is activated (Command mode = 1), no data is sent by the PLC to the
Leuze end device via the gateway. The data from the MA to the PLC is transmitted in the
selected operating mode (Transparent/Collective).
With the Command mode, it is possible to set various device-specific bits in the data- or
parameter field that execute the corresponding serial commands (e.g., v, +, -, etc.). If, for
example, the version of the Leuze end device is to be queried, the corresponding bit is to
be set so that a "v" is sent to the Leuze device with the <STX> v <CR> <LF> frame.
The Leuze end device also answers the gateway with data (e.g. bar code content, NoRead,
device version, etc.) in response to most commands. The answer is immediately passed on
to the PLC by the gateway.
Notice!
The parameters available for the individual Leuze devices are listed in chapter 16.
Command mode cannot be used with hand-held scanners.

Commissioning and configuration
12.1
Measures to be performed prior to the initial commissioning
 Before commissioning, familiarize yourself with the operation and configuration of the
MA 204i.
 Before connecting the supply voltage, recheck all connections and ensure that they
have been properly made.
The Leuze device must be connected to the internal RS 232 device interface.
Connecting the Leuze device
 Open the housing of the MA 204i and guide the corresponding device cable (e.g., KB 031
for BCL 32) through the middle threaded opening.
 Connect the cable to the internal device interface (X30, X31 or X32, see chapter 7.5.1).
 Use rotary switch S4 (see chapter 8.2.5) to select the connected device.
 Now screw the PG cable gland into the threaded opening to provide strain relief and
ensure protection class IP 65.
Setting the PROFIBUS device address
By setting the PROFIBUS address, the MA 204i is assigned its respective station number.
Each network device is thereby automatically informed that it is a slave on the PROFIBUS
with its specific address and that it is initialized and queried by the PLC.
The PROFIBUS permits an address range from 0 to 126. Other addresses must not be used
for data communication.
Hundreds

Leuze electronic
Commissioning and configuration
12.3.1 Step 1 – Preparing the control system (S7 PLC)
In the first step, the control is prepared for consistent data transmission.
During programming the control system must be prepared for consistent data transmission.
This varies from control system to control system. The following possibilities are available
for the Siemens control systems.
S7
The specific function blocks SFC 14 for input data and SFC 15 for output data must be
integrated in the program. These are standard function blocks and are used to facilitate
consistent data transmission.
Notice!
If an S7 control is used, you need to ensure that Simatic-Manager Version 5.4 +
service pack 5 (V5.4+SP5) or higher is used.
12.3.2 Step 2 – Installation of the GSD file
For the subsequent configuration of the PROFIBUS devices, e.g., MA 204i, the
corresponding GSD file must be loaded first.
General information on the GSD file
The term GSD stands for the textual description of a PROFIBUS device model.
You can find the GSD file at
www.leuze.com -> Download -> identify -> Stationary and hand-held bar code
readers.
All data in modules required for operating the MA 204i is described in this file. These are
input and output data and device parameters for the functioning of the MA 204i and the definition of the control and status bits.
If parameters are changed, e.g., in the project tool, these changes are stored on the PLC
side in the project, not in the GSD file. The GSD file is a certified and integral part of the
device and must not be changed manually. The file is not changed by the system either.
The functionality of the MA 204i is defined via GSD parameter sets. The parameters and
their functions are structured in the GSD file using module. A user-specific configuration
tool is used during PLC program creation to integrate the required modules and configure
them appropriately for their respective use. During operation of the MA 204i on the
PROFIBUS DP, all parameters are set to default values. If these parameters are not changed
by the user, the device functions with the default settings delivered by Leuze electronic.
For the default settings of the MA 204i, please refer to the following module descriptions.
Leuze electronic
MA 204i

The GSD file can support an arbitrary number of languages in one file. Every GSD file
contains a version of the MA 204i device model. This is also reflected in the file name.
Commissioning and configuration
12.3.3
Step 3 – Hardware configuration of the S7 PLC: Configuration
For the configuration of the PROFIBUS system using the HW Config of the
SIMATIC Manager, insert the MA 204i into your project and assign a unique address
(0 … 125).
Notice!
Ensure that the address is the same as the address configured in the device.
Figure 12.1: Assignment of the device address
12.3.4
Step 4 – Configuration of the modules
 Now select a corresponding data module for the input and output area.
A number of combinable modules are available with various data lengths (4, 8, 12, 16, 20,
32 … 128 bytes). In total, a maximum of 244 bytes are possible for both the input bytes and
for the output bytes.
62
MA 204i
Leuze electronic
Commissioning and configuration
Notice!
Because the data module contains 2 bytes for the control and status bytes, the actual user
data length is always 2 bytes smaller than the selected data module.
E.g., when using the data module with 12 bytes, there are effectively 10 bytes available for
user data on the Leuze device after subtracting the 2 bytes for status and control bytes.
Recommendation
In most cases, the 4-byte module is sufficient for the output module.
A larger module is needed, for example, if a BCL bar code scanner is to be configured by
means of PT-sequences, or an RFID transponder is to be described. In these cases, larger
data modules are usually sensible.
Examples of sensible settings for corresponding Leuze devices
BPS 8
• Input module: 8 bytes
• Output module: 4 bytes
AMS
• Input module: 8 bytes
• Output module: 8 bytes
• Input module: individual
The size of the input module is dependent on the number of digits of the bar code or
2D code that is to be read. For example, with an 12-digit bar code (+ 2 bytes of status
bytes), the input module with 16 bytes is sensible.
• Output module: none
Because the hand-held scanner does not typically send any data, no output module
is necessary.
BCL bar code scanners, RFID devices (RFM, RFI and RFU), LSIS 122 and LSIS 4x2i
• Input module: individual
The size of the input module is dependent on the number of digits of the bar code,
RFID code or 2D code that is to be read. For example, with an 18-digit bar code
(+ 2 bytes of status bytes), the input module with 20 bytes is sensible.
• Output module: 4 bytes

PROFIBUS devices
• Cyclical data exchange

General information on the PROFIBUS implementation of the
MA 204i
12.5.1
Communication profile
The communication profile defines how participants serially transmit their data via the
transmission medium. The MA 204i supports the communication profile for automation
systems and Decentral Periphery -> PROFIBUS DP.
DP communication profile
The PROFIBUS DP communication profile is designed for efficient data exchange on the
field level. Data exchange with the decentral devices occurs primarily cyclically. The necessary communication functions are defined in the DP base functions. The DP optionally offers
acyclic communication services as well. These are used for configuring, operating,
observing and alarm handling.
In order to be able to perform data exchange, services are defined which PROFIBUS DP
differentiates between on the basis of the data access points transmitted in the telegram
header.
The MA 204i profile is based on the PROFIBUS profile for identification systems.
12.5.2
Bus-access protocol
The PROFIBUS communication profiles (DP,FMS) use a uniform bus-access process. It is
implemented by layer 2 of the OSI model. The bus-access control (MAC) defines the process
for specifying the point in time at which a network device can transmit data. It must ensure
that no more than one participant has permission to transmit at any given time. The
PROFIBUS bus-access process includes the token-passing process and the master-slave
process.

process
Table 12.1:
Description
MA 204i
With this process, the bus-access permission is distributed by means of
a token. The participant obtains permission to transmit with the token. The
token wanders between the master devices in the ring in a permanently No
defined time frame. This type of bus access is used for communication
between the masters.
Various slave devices are assigned to a master. The master can address
the slaves which are assigned to it and fetch messages from them. The Yes
master always has the initiative.
PROFIBUS bus-access processes
The two processes can also be mixed in order to create a multi-master system. The MA 204i
functions both in a mono-master system as well as in a multi-master system.
Notice!
In 2007, the PROFIBUS DP was extended by the DPV2 specification. The specification will
then also permit slave-slave communication. The MA 204i does not support this type of
communication.
12.5.3 Device types
With the PROFIBUS DP, there are two types of master and one type of slave:
Description
Class 1 master
(DPM1)
Class 1 masters are defined for the user-data communication
(e.g. PLC, PC).
Class 2 Master
(DPM2)
Class 2 masters are defined for commissioning purposes. Additional
services facilitate easier configuration as well as device diagnosis.
Slave
The slave is a peripheral device which makes available input data for
X
the control and receives output data from the control.

12.5.5
Modular structure of the parameter
The PROFIBUS DP functionality of the device is defined via parameter sets which are clustered in modules. The modules are included in a GSD file, which is supplied as an integral
part of the device. By using a user-specific project tool, such as, e.g., Simatic Manager for
the Siemens programmable logic control, the required modules are integrated into a project
during commissioning and its settings and parameters are adjusted accordingly. These
modules are provided by the GSD file.
Notice!
All input and output modules described in this documentation are described from the
controller's perspective:
- Input data arrives at the controller.
- Output data is sent out by the controller.
Detailed information on how to prepare the control and the GSD file may be found in chapter
"Configuration steps for a Siemens Simatic S7 control" on page 60.
For the default settings of the MA 204i, please refer to the following module descriptions.
Notice!
Please note that the set data is overwritten by the PLC!
Some controls make available a so-called "universal module". This module must not be
activated for the MA 204i!
From the perspective of the device, a distinction is made between PROFIBUS parameters
and internal parameters. PROFIBUS parameters are all parameters that can be changed via
the PROFIBUS and are described in the following modules. Internal parameters, on the other
hand, can only be changed via a service interface and retain their value even following a
PROFIBUS configuration.
During the configuration phase, the MA 204i receives parameter telegrams from the
IO Controller (master). Before this is evaluated and the respective parameter values are set,
all PROFIBUS parameters are reset to default values. This ensures that the parameters of
modules that are not selected are set to the default values.

12.5.6 Permanently defined parameters/device parameters
On the PROFIBUS, parameters may be stored in modules or may be defined permanently
in a PROFIBUS participant.
The permanently defined parameters are called "common" parameters or device-specific
parameters, depending on the configuration tool.
These parameters must always be present. They are defined outside of the configuration
modules and are permanently anchored in the telegram header.
In Simatic Manager, the permanently defined parameters are set via object properties of
the device. The module parameters are set via the module list of the selected device. By
selecting the project properties of a module, the respective parameters may be set if
required.
The following list contains the device parameters that are permanently defined in the

Overview of the project modules
When using PROFIBUS modules, the parameters are assembled dynamically, i.e., only the
parameters that were selected by the activated modules are changed.
The MA 204i has parameters (device parameters) that must always be present. These
parameters are defined outside of modules and are thus linked to the base module (DAP).
In the current version, several modules are available for use. A device module (DAP, see
Permanently defined parameters/device parameters) is used for basic scanner configuration
of the MA 204i and is permanently integrated into the project. Further modules may be
included into the project according to requirements and application.
The modules fall into the following categories:
• Parameter module for the configuration of the MA 204i.
• Status or control modules that influence the input/output data.
• Modules that may include both parameters and control or status information.
A PROFIBUS module defines the existence and meaning of the input and output data. In
addition, it defines the necessary parameters. The arrangement of the data within a module
is defined.
The composition of the input/output data is defined via the module list.
The MA 204i interprets the incoming output data and triggers the appropriate reactions in
the MA 204i. The interpreter for processing the data is adapted to the module structure
during initialization.
The same applies for the input data. Using the module list and the defined module properties, the input data string is formatted and referenced to the internal data.
During cyclic operation, the input data is then passed on to the controller.
During the startup or initialization phase, the MA 204i sets the input data to an initial value
(usually 0).
Notice!
The modules can be grouped together in any order in the engineering tool. Note, however,
that many MA 204i modules contain related data. It is important to maintain the consistency
of these data.
The MA 204i offers different modules. Each of these modules may only be selected once;
otherwise, the MA 204i ignores the configuration.
The MA 204i checks its max. permissible number of modules. The control also reports an
error if the input and output data across all selected modules exceed a total length of 488
bytes. A maximum of 244 bytes can be used for both the input data and for the output data.
The specific limits of the individual modules of the MA 204i are declared in the GSD file.

12.5.8 Preparing the control system for consistent data transmission
During programming the control system must be prepared for consistent data transmission.
This varies from control system to control system. The following possibilities are available
for the Siemens control systems.
The specific function blocks SFC 14 for input data and SFC 15 for output data must be integrated in the program. These are standard function blocks and are used to facilitate consistent data transmission.
Notice!
If an S7 control is used, you need to ensure that Simatic-Manager Version 5.4 +
service pack 5 (V5.4+SP5) or higher is used.
12.6
Variable configuration of the communication data width
The communication of the MA 204i with the fieldbus systems can be configured with a variable data width; the upper limit is restricted by the fieldbus. The following sizes are available
for the data frame for PROFIBUS DP:
4, 8, 12, 16, 20, 24, 28, 36, 64, 128 bytes
The small data lengths (< 28 bytes) are particularly of interest for use with bar code scanners
(BCL). The larger data lengths are, on the other hand, relevant for 2D code scanners (handheld scanners, LSIS) and RFID.
Taking into consideration the maximum permissible data width of 244 bytes, multiple
modules can also be used for the input data or combined with one another. The combination
of module 128 and module 64, for example, yields an input data length of 192 bytes.

To commission a read station, you must prepare the Leuze device on the MA 204i for its
reading task. Communication with the Leuze device occurs via the service interface.
Notice!
Further information on connecting and using the service interface.
 To do this, connect the Leuze device to the MA 204i.
Depending on the Leuze device, this occurs either via a connection cable (accessory no.:
KB 031-1000) or directly on the MA 204i. The service connector and corresponding
switches can be accessed with the housing cover open.
 Select the "DEV" service switch position.
Connect the service interface; call up the terminal program
 Connect your PC to the service connector via the RS 232 cable.
 On the PC, call up a terminal program (e.g., BCL-Config) and check whether the interface
(COM 1 or COM 2) to which you have connected the MA 204i is set to the following Leuze
standard setting: 9600 baud, 8 data bits, no parity, 1 stop bit and STX, data, CR, LF.
You can download the config. tool from www.leuze.de -> Download -> Identify for BCL,
RFID, VR etc.
In order to communicate with the connected Leuze device, the STX, data, CR, LF framing
must be set on the PC terminal program, as the Leuze device is preconfigured ex works for

For a description of device configuration and the required codes, please see the corresponding documentation at www.leuze.com -> Download -> identify -> Bar code hand-held
readers or 2D code hand-held readers.
12.7.1.1 Cable-connected hand-held scanners on the MA 204i
All hand-held scanners and mobile combi devices available in the Leuze electronic product
line can be used with the corresponding connection cable.
When using the MA 204i, the voltage supply of the hand-held scanner (5 V/at 1 A) can be
connected to the interface by means of a cable via the 9-pin Sub-D connector (voltage on
PIN 9). The corresponding cable is to be selected for the respective hand-held scanner and
ordered separately. The 9-pin Sub-D cable (KB JST-HS-300, Part no. 50113397) is
connected to this cable, which is connected to the MA 204i. This cable must also be ordered
separately.
In this example, triggering occurs by means of a trigger button on the hand-held scanner.
All cableless hand-held scanners and mobile combi devices available in the Leuze electronic
product line can be used with the corresponding connection cable via the base station.
A 230 VAC connection (socket) is usually necessary for the charging station. Here, a data
connection of the charging station is established with the MA 204i. The corresponding cable
is to be selected for the respective hand-held scanner and ordered separately. The 9-pin
Sub-D cable (KB JST-HS-300, Part No. 50113397) is connected to this cable, which is
connected to the MA 204i. This cable must also be ordered separately.
In this example, triggering occurs by means of a trigger button on the hand-held scanner.
The following codes for configuring the devices are necessary for these devices as well.

Specific features in the operation of an RFM/RFI
When using the MA 204i in connection with an RFID device, we recommend a data width
of at least 24 bytes to be able to transmit information to or from the reader in a telegram.
Shown here is a sample telegram for a write command in combination with an RFID device.
Notice!
Also note that all characters which are sent to a transponder are hex-encoded ASCII
characters. Each of these (hexadecimal) characters is, in turn, to be handled as an individual
ASCII character and converted to hexadecimal format for transmission via the fieldbus.

Serial interface and Command mode
The corresponding Leuze end device can be selected while configuring the fieldbus gateway
(see chapter 9 "Configuration").
The exact specifications for the individual Leuze end devices can be found in the following
sections and in the device description.
The corresponding serial command is sent to the Leuze end device in Command mode. To
send the corresponding command to the RS 232 device after activating the Command
mode in byte 0 (control bit 0.0), set the corresponding bit in byte 2.
The Leuze end device also responds to most commands by sending data, such as the bar
code contents, NoRead, device version, etc., back to the gateway. The answer is not evaluated by the gateway, but is instead passed on to the PLC.
Additional parameters such as the baud rate and data mode can be configured via the GSD
file with the "USE GSD settings" enable function. The data frame and, if necessary, the length
are specified via the switch position. However, the changes have to match the device
settings.
For the BPS 8, AMS and hand-held scanners, a number of specific features are to be noted.
16.1
Standard setting, KONTURflex (S4 switch position 0)
The distance between two successive telegrams (without frame) must be more than 20 ms
in this switch position, since there is otherwise no clear separation between them. If necessary, the settings have to be adjusted on the device.
Leuze measuring sensors with RS 232 interface (such as a KONTURflex Quattro RS) do not
necessarily use a telegram frame, which is why these are also operated in switch position 0.
