General information
1.3Description of functions
The MA 235i modular interfacing unit is used to connect Leuze devices directly to the
fieldbus.
Bar code reader:BCL 8, 22, 300i, 500i, 600i, 90, 900i
This is accomplished by transmitting the data from the DEV via an RS 232 (V.24) interface
to the MA 235i where a module converts it into the CANopen format. The data format on
the RS 232 interface corresponds to the Leuze standard data format (9600bd, 8N1 and STX,
data, CR, LF).
The corresponding Leuze devices are selected using a rotary code switch on the circuit
board of the connector unit. Many additional RS 232 devices can be connected through a
universal position.
Leuze electronic can only provide support for the devices offered in the product range.

3Fast commissioning / operating principle
Notice!
Below you will find a short description for the initial commissioning of the CANopen
gateway MA 235i. Detailed explanations for the listed points can be found throughout the
handbook.
3.1Mounting
The gateway mounting plate MA 235i can be mounted in two different ways:
• using four threaded holes (M6) or
• using two M8x6 screws on the two lateral grooves.
3.2Device arrangement and selection of the mounting location
Ideally, the MA 235i should be mounted so that it is easily accessible near the Ident device
in order to ensure good operability, e.g., for configuring the connected device.
Detailed information can be found in chapter 6.3.1.
3.3Electrical connection
The devices from the MA 2xxi family feature four M12 connectors/sockets which are coded
differently depending on the interface.
The voltage supply (PWR IN) as well as the switching inputs/outputs (PWR OUT or PWR IN)
are connected there. The number and function of the switching inputs/outputs is dependent
on the connected end device.
An internal RS 232 interface is used for connecting the respective Leuze device. Another
internal RS 232 interface functions as a service interface for configuring the connected
device via a serial null modem cable.
Figure 3.1:MA 235i connections
Detailed information can be found in chapter 7.
10MA 235iLeuze electronic
3.3.1Connecting the Leuze device
OnesTens
To connect the Leuze device to the internal RS 232 device interface, open the housing
of the MA 235i and lead the corresponding device cable (see chapter 14.7) 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.
Set CANopen device address
By setting the CANopen address, the MA 235i is assigned its respective station number.
Each network device is thereby automatically informed that it is a slave on the CANopen
with its specific address and that it is initialized and queried by the PLC.
The CANopen permits an address range from 0 to 127, the MA a range from 0 to 99. Other
addresses must not be used for data communication.
Set the station address of the gateway using the two rotary switches S1 and S2 (ones
and tens places).
Fast commissioning / operating principle
Figure 3.2:Rotary switch for setting the address
Leuze electronicMA 235i11
TNT 35/7-24V
Fast commissioning / operating principle
Set CANopen baud rate on the MA
The CANopen baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 235i via the baud rate selector switch. Only if the baud rates are
the same is communication with the MA 235i possible.
Set the baud rate of the gateway via the S3 rotary switch to the value defined in the control.
Only then may the supply voltage be applied.
Upon startup of the MA 235i, the device selection switch is queried and the gateway automatically sets itself to the Leuze device.
Connecting functional earth FE
Ensure that the functional earth (FE) is connected correctly.
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth connection.
12MA 235iLeuze electronic
Fast commissioning / operating principle
3.3.2Connecting 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.
The ready-made cables listed in chapter 14.6.4 are preferred for connecting the gateway
to the fieldbus via the HOST / BUS IN connection.
If applicable, use the BUS OUT connection if you would like to construct a network with
linear topology.
3.4Starting the device
Apply the supply voltage +18 … 30VDC (typ. +24VDC); the MA 235i starts up.
The PWR LED displays that it is ready for operation.
3.5MA 235i on the CANopen
Install the EDS file corresponding to the MA 235i in your planning tool/the control.
Notice!
You can find the EDS file at: www.leuze.com
The MA 235i is configured in the planning tool/control by means of the EDS file. The MA 235i
is assigned an address in the planning tool, which then has to be set in the MA 235i via the
S1 and S2 address switches. Only if the addresses are the same between the MA 235i and
the control can communication be established.
After all parameters have been set in the planning tool/control, the download to the MA 235i
takes place. The set parameters are now stored on the MA 235i.
Afterwards, all MA 235i parameters should be stored via upload in the control. This aids in
retaining the parameters during device exchanges, as they a re now also stored centrally in
the control.
The CANopen baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 235i via the S3 baud rate selector switch.
Only if the baud rates are the same is communication with the MA 235i possible.
Detailed information can be found in chapter 12.

4.1General 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, …) into 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.
4.2Characteristics of the connector units
A special characteristic of the MA 235i device family are three function modes:
1.Transparent mode
In this function mode, the MA 235i 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".

(V.24)
The MA 235i 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 235i where a module
converts it into the fieldbus format. The data format of the RS 232 interface corresponds to
the standard Leuze data format.
Device description
Figure 4.1:Connection of a Leuze device (BCL, RFI, RFM, …) to the fieldbus
The cable of the respective Leuze device is guided through cable bushings with PG cable
glands into the MA 235i and connected there with the PCB connectors.
The MA 235i is intended as a gateway for any RS 232 devices, e.g., BCL 300i, 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.

Device description
4.4Operating modes
For fast commissioning, the MA 235i 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 235i and the network settings of the MA can be
displayed. 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.
Figure 4.2:Service-switch switch positions
Notice!
If the service switch is on one of the service settings, the CAN 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.

4.5Fieldbus systems
Various product variants of the MA 2xxi series are available for connecting to different
fieldbus systems such as PROFIBUS DP, PROFINET-IO, DeviceNet, CANopen and Ethernet
or EtherCAT.
Device description
4.5.1CANopen
General information on CANopen
Figure 4.4:Bus topology
Leuze electronicMA 235i17
TNT 35/7-24V
Device description
The CAN bus is a serial 2-wire bus system to which all participants are connected in parallel (i.e., using short stub cables). To avoid reflections, the bus must be terminated with a
terminating resistor of 120ohm at each end of the trunk line. Terminating resistors are also
required for very short trunk line cable lengths.
If the MA 235i is the last participant in the trunk line, the trunk line can be terminated via
the M12 bus OUT connection. For this purpose, Leuze electronic offers an M12 terminating resistor, see chapter 14 "Type overview and accessories".
Bus line (trunk line)
For CAN, the maximum cable length of the trunk line is predominantly limited by the signal
propagation time. The multi-master bus-access process (arbitration) requires that the signals are present virtually simultaneously at all nodes/participants. Therefore, the cable
length of the trunk cable must be adapted to the baud rate.
Baud rateBus length
1Mbit/s< 20m
800kbit/s< 50m
500kbit/s< 100m
250kbit/s< 250m
125kbit/s< 500m
50kbit/s< 1000m
20kbit/s< 2500m
Stub cables (drop lines)
If possible, stub cables should be avoided because they cause signal reflections as a matter of principle. Generally, the reflections caused by stub cables are not critical, however, if
the following stub cable lengths are not exceeded.
Baud rateLength of stub cablesTotal length of all stub cables
Stub cables must not be fitted with terminating resistors. If the MA 235i is integrated into a
stub cable, the M12 bus OUT connection must not be terminated.

Address assignment
Notice!
The participant-specific address for CANopen is also called the Node ID. Throughout this
handbook, the term "address" is used, which is identical to "Node ID".
Each participant connected to CANopen is assigned its own address (Node ID). Up to
127 participants can be connected to one network. The addresses of the MA range from
1 to 99. The address 0 is usually reserved for the CANopen master.
Notice
The "Layer Setting Services (LSS)" function is not supported by the MA 235i. For this reason,
the address must be set manually. See "Switch for address selection in the fieldbus" on
page 40.
The "Layer Setting Services (LSS)" function is not supported by the MA 235i. The baud rate
must be set manually. See "Switch for setting the baud rate" on page 40.

on the connected end device. Two additional M12 connectors/sockets are used for connection to the fieldbus. Both of these connections are A-coded.
An internal RS 232 interface is used for connecting the respective Leuze device. Another
internal RS 232 interface functions as a service interface for configuring the connected
device via a serial null modem cable.

Connecting functional earth FE
Notice!
Ensure that the functional earth (FE) is connected correctly. Unimpaired operation is only
guaranteed when the functional earth is connected properly. All electrical disturbances (EMC
couplings) are discharged via the functional earth connection.
Switching input/output
The MA 235i is equipped with the SWIO_1 and SWIO_2 switching inputs/outputs. This is
located on the PWR IN M12 connector and on the PWR OUT M12 connector. The connection of the switching inputs/outputs from PWR IN to PWR OUT can be interrupted by means
of a jumper. In this case, only the switching input and output on PWR IN are active.
The function of the switching inputs and outputs is dependent on the connected Leuze
device. Detailed information on this topic can be found in the respective operating instructions.

Following activation, this interface enables access via the RS 232 to the connected Leuze
device and the MA for configuration using the 9-pin Sub-D. The connection between the
fieldbus interface and the device interface is switched off during access. The fieldbus itself
is, however, not interrupted as a result.
The service interface can be accessed once the MA 235i housing cover has been removed
and features a 9-pin Sub-D connector (male). A crossed RS 232 connection cable is required
to make the RxD, TxD and GND connections. A hardware handshake via RTS, CTS is not
supported at the service interface.

Attention!
For the service PC to function, the RS 232 parameters must be the same as those of the
MA. The Leuze standard setting of the interface is 9600Bd, 8N1 and STX, data, CR, LF.
Notice!
To configure the devices connected to the external interface, e.g., BCL 8 (JST plug connector "X30"), a cable specially configured for this purpose is necessary. The service switch must
be in the "DEV" or "MA" position (Service Leuze device/MA).

10.1Structure 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:

received. At the end of a read cycle, this bit must be toggled
R-ACK
in order to be able to receive the next data set. This toggle
bit is switched by the master after valid received data has
been read out of the input bytes and the next datablock can
be requested. If the gateway detects a signal change in the
R-ACK bit, the next bytes are automatically written from the
receive buffer to the input data words and the BLR bit toggled. Further toggling erases the memory (to 00h).

Copy to transmit buffer
(transmission data to transmit buffer)
Toggle bit: Changing this bit writes the data from the PLC to
CTB
the transmit buffer of the fieldbus gateway. This is used, for
example, for long command strings which must be transmitted to the connected ident device.
The CTB toggle bit is switched whenever transmit data is not
to be sent directly via the serial interface, but instead transferred to the transmit buffer.
Notice!
The state change of the CTB bit signals the MA that the data is going into the buffer; therefore,
it's essential to observe the order!
When the CTB is not used, the telegram (which fits in one cycle) is transmitted directly to
the RS 232 interface. Please make sure it is complete!
10.4RESET function / deleting memory
For many applications, it is helpful to be able to reset the MA buffer (in Collective mode) or
status bits.
The following bit pattern can be transmitted from the PLC for this purpose (if >20 ms is

Modes
11Modes
11.1Functionality of the data exchange
The fieldbus gateway has two different modes that can be selected via the PLC:
• Transparent mode (standard setting)
In Transparent mode, all data is 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
20ms, 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 00
because unnecessary bytes are also filled with 00
• 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.
in the data range, the MA cuts the telegram off

.

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 235i ("DEX" bit = "0"), the "R-ACK" bit must be
toggled once as read confirmation to release data transmission for the next read cycle.
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.
Used status and control bits:
•DLC
•BLR
•DEX
•R-ACK
11.1.2 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.
Modes
Notice!
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
•W-ACK
Leuze electronicMA 235i53

Modes
If PLC data is provided and transferred without a state change of the CTB bit, it goes directly

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.
This means that the hex value "2B" (corresponds to a " +" ) i s to b e e nt e red in control or output
byte 2. To deactivate the reading gate, a "2D" (hex) must be used instead (corresponds to
a "-" ASCII).

11.1.3 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.
Examples for the activation of a Leuze device
In Command mode, control or output byte 0.0 is to be set for activating the Command mode.
Only the corresponding bit (control or output byte 2.1) then needs to be set for activating
and deactivating the reading gate.

12Commissioning and configuration
12.1Measures to be performed prior to the initial commissioning
Before commissioning, familiarize yourself with the operation and configuration of the
MA 235i.
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 235i and lead the corresponding device cable (see chapter
14.7) 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.
Set CANopen device address
By setting the CANopen address, the MA 235i is assigned its respective station number.
Each network device is thereby automatically informed that it is a slave on the CANopen
with its specific address and that it is initialized and queried by the PLC.
The CANopen permits an address range from 0 to 127, the MA a range from 0 to 99. Other
addresses must not be used for data communication.
Set the station address of the gateway using the two rotary switches S1 and S2 (ones
and tens places).

Set CANopen baud rate on the MA
The CANopen baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 235i via the baud rate selector switch. Only if the baud rates are
the same is communication with the MA 235i possible.
Set the baud rate of the gateway via the S3 rotary switch to the value defined in the control.
Only then may the supply voltage be applied.
Upon startup of the MA 235i, the device selection switch is queried and the gateway
automatically sets itself to the Leuze device.

Check the applied voltage. It must be in the range between +18V … 30VDC.
Connecting functional earth FE
Ensure that the functional earth (FE) is connected correctly.
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth connection.
On delivery, the SWIO 1/2 are connected in parallel on PWR IN/OUT. This connection can
be separated with a jumper.
12.1.1 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.
The ready-made cables listed in chapter 14.6.4 are preferred for connecting the gateway
to the fieldbus via the HOST / BUS IN connection.
If applicable, use the BUS OUT connection if you would like to construct a network with
linear topology.
12.2Starting the device
Apply the supply voltage +18 … 30VDC (typ. +24VDC); the MA 235i starts up.
The PWR LED displays that it is ready for operation.

12.3MA 235i in the CANopen system
Install the EDS file corresponding to the MA 235i in your planning tool/the control.
Notice!
You can find the EDS file at: www.leuze.com
The MA 235i is configured in the planning tool/control by means of the EDS file. The MA 235i
is assigned an address in the planning tool, which then has to be set in the MA 235i via the
S1 and S2 address switches. Only if the addresses are the same between the MA 235i and
the control can communication be established.
After all parameters have been set in the planning tool/control, the download to the MA 235i
takes place. The set parameters are now stored on the MA 235i.
Afterwards, all MA 235i parameters should be stored via upload in the control. This aids in
retaining the parameters during device exchanges, as they a re now also stored centrally in
the control.
The CANopen baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 235i via the S3 baud rate selector switch.
Only if the baud rates are the same is communication with the MA 235i possible.
In a CANopen network, all participants have in principle equal privileges. Each participant
can initiate its data transmission independently. Here, the arbitration specified by the CIA
controls the access of the individual participants to the network. Generally, each CAN participant listens in on the bus. The transmission process is started only if the bus is not occupied
by another CAN participant. When transmitting, the current bus status is always compared
to the own transmitted frame.
If several participants start a transmission simultaneously, the arbitration process decides
which participant gains access to the network next. The individual participants are integrated into a prioritization scheme via their bus address and the type of data to be transmitted (index address of the data). Process data (PDOs) of a device are transmitted with a
higher priority than, for example, variable objects (SDOs) of a device.
The node address of the participant is another criterion for prioritizing a participant in the
network. The smaller the node address, the higher the priority of the participant in the
network.
Since every participant compares its own priority with that of the other participants at the
time of bus access, the participants with low priority discontinue their transmission activities
immediately. The participant with the highest priority obtains temporary access to the bus.
The arbitration process controls the access of all participants so that even participants with
a low priority have access to the bus.

Commissioning and configuration
12.4Starting the MA 235i in the CANopen system
During starting up, the gateway runs through different states which are explained in brief in
the following.
INIT
The MA 235i initializes itself. No direct communication between the master and MA 235i is
possible. The CANopen master will transfer the MA 235i step by step into the "operational"
state.
In the status change from "INIT" to "PREOP", the TwinCAT or master writes the so-called
CANopen address (=station address) to the respective register of the CANopen slave
controller (here: MA 235i). This CANopen address is typically specified in relation to the position, i.e., the master's address is 1000, the first slave's address is 1001, etc. This is also
called the auto-increment method.
PRE-OPERATIONAL
The master and the MA 235i exchange application-specific initializations and devicespecific parameters. In the PRE-OPERATIONAL state, configuration is initially possible via
SDOs only.
SAFE-OPERATIONAL
The "Start Input Update" command puts the gateway into the "Safe-Operational" state. The
master produces output data, but input data are not considered. This means the MA 235i
does not return output data (=PLC input data) in SAFEOP. The gateway does not process
input process data (=PLC output data). Mailbox communication via CoE services is possible.
OPERATIONAL
The "Start Output Update" command puts the gateway into the OPERATIONAL state. In
this state, the MA 235i supplies valid input data and the master valid output data. After the
MA 235i has detected the data received via the process data service, the state transition is
confirmed by the MA 235i. If the activation of the output data was not possible, the gateway
remains in the SAFE OPERATIONAL state and outputs an error message.
12.4.1 Device profile
CANopen describes the characteristics of participants in so-called profiles. However, a
device profile for gateways is not defined.
The MA 235i is designed as a slave participant and cannot take on master functionality.
62MA 235iLeuze electronic
12.4.2 Object directories
All process data and parameters are stored as objects in the MA 235i. The object directory
of the MA 235i is the compilation of all process data and parameters of the gateway.
An object directory is structured such that some objects within a device profile are mandatory while others are freely definable and stored in the manufacturer-specific object area.
The objects are uniquely identified using an index addressing scheme. The structure of the
object directory, the assignment of the index numbers, as well as some mandatory entries
are specified in the CIA standard DS301 for CANopen.
EDS file
For the user, the object directory of the MA 235i is stored as an EDS file (Electronic Data
Sheet).
The EDS file contains all objects with index, sub-index, name, data type, default value,
minimum and maximum, and access privileges. That means the EDS file describes the entire
functionality of the MA 235i, and it is possible to adjust both the communication of the
gateway with the control and the RS 232 interface.
Notice!
The size of the input and output data is permanently set for CANopen: the MA 235i always
provides the process data for transmission in this form: 8 bytes Tx and 8 bytes Rx.
The EDS file has the name MA 235i.eds and is available for download on the Leuze home
page.
Vendor ID for the MA 235i
The Vendor ID assigned by Leuze electronic for the MA 235i is 121h = 289d.
Detailed information on the device description file and the object directory can be
found in chapter 12.4.6.
Commissioning and configuration
12.4.3 SDOs and PDOs
The data exchange in CANopen distinguishes between service data objects (SDOs), which
are used for transmitting the service data (parameters) from and to the object directory, and
process data objects (PDOs), which are used to exchange the current process states.
12.4.4 SDOs
By using SDOs, all entries of the object directory can be accessed. Within one SDO call,
only one object can be accessed at any one time. For this reason, a service data telegram
must have a protocol structure which describes the exact target address by means of
index and sub-index addressing. SDO telegrams place a part of the SDO addressing into
the user data area. Eventually, a user data area with a width of 4 bytes out of the possible
8 bytes of user data remains for each SDO telegram.
The target address always responds to SDO transfers.
In the following, the index and sub-index address of the MA 235i parameters and vari-
ables can be found in the individual object descriptions.
Leuze electronicMA 235i63
TNT 35/7-24V
Commissioning and configuration
12.4.5 PDOs
PDOs are objects (data, variables and parameters) from the object directory compiled
(mapped) by the device manufacturer. A maximum of 8 bytes of user data from various
objects can be mapped into one PDO.
A PDO can be received and evaluated by each participant (node). The model is referred to
as the producer-consumer procedure.
Since there is no protocol structure in the telegra m of a PD O, t he p articipants in the network
for whom these data are intended mu st k now how the user data in the data area of the PDO
are structured (which data are stored where in the user data area).
The exchange of process data is supported by the MA 235i via the following accesses:
• Event-controlled data transfer
Here, the data of a node are transmitted as a message whenever a change to the present state occurs.
• Polling with remote frames
The CAN node which has been defined as master in the network requests the desired
information via query (via remote frame). The participant which has this information
(or the required data) responds by sending the requested data.
• Synchronized mode
CANopen permits simultaneous querying of inputs and states of different participants
and the simultaneous change of outputs or states. For this purpose, one uses the synchronization telegram (SYNC) transmitted by a master.
The SYNC telegram is a broadcast to all network devices with high priority and without
data content. Generally, the master sends the SYNC telegram cyclically.
Participants working in synchronized mode read their data when receiving the SYNC
message and then transmits them immediately afterwards as soon as the bus permits
this (see explanation regarding arbitration process).
As the SYNC process can very quickly lead to high bus loads, another distinction is
made between "event-controlled synchronization" and a "timer synchronization".
• Time-controlled transmission
In this case, the transmission of a PDO is triggered when an adjustable time period
has elapsed. The time-controlled transmissions are set individually for each PDO via
the so-called "inhibit time" or an "event timer". The respective parameters can be
found in the objects 1800
• Node monitoring
Heartbeat and guarding mechanisms are available for failure monitoring of the
MA 235i. This is particularly important for CANopen, as the MA 235i may not respond
regularly in the event-controlled operating mode. In case of guarding, the participants
are cyclically queried for their state via data request telegrams (remote frame). In case
of heartbeat, the nodes transmit their state themselves.
Heartbeat and guarding / life time are standard communication objects from the
DS301 CANopen specification. The corresponding objects here are:
- Heartbeat 1017
- Guarding / Life time factor 100Ch and 100D
to 1803h for the corresponding PDOs.

Commissioning the Leuze device
To commission a read station, you must prepare the Leuze device on the MA 235i for its
reading task. Communication with the Leuze device occurs via the service interface.
Notice!
For further information on connecting and using the service interface, see chapter 9 "Configuration".
To do this, connect the Leuze device to the MA 235i.
Depending on the Leuze device, this occurs either via a connection cable (accessory no.:
KB 031-1000) or directly on the MA 235i. 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

Commissioning and configuration
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
this frame character.
STX (02h):Prefix 1
CR (0Dh):Postfix 1
LF (0Ah):Postfix 2
Operation
Switch the MA 235i to switch position "RUN" (operation).
The Leuze device is now connected to the fieldbus. Activation of the Leuze device can now
occur via the switching input on the MA 235i, via the process data word Out bit 1 (bit 0.2)
or by transmitting a "+" command to the Leuze device (see chapter 16 "Specifications for
Leuze end devices"). For further information on the fieldbus transmission protocol, see see
chapter 10 "Telegram".
Reading out information in service mode
Set the service switch of the gateway to switch position "MA" (gateway).
Send a "v" command to call up all service information of the MA 235i.
An overview of the available commands and information can be found in chapter "Reading
out information in Service mode" on page 41.
12.5.1 Specific feature for the use of hand-held scanners
(bar code and 2D devices, combi devices with RFID)
Notice!
A description of the device configuration and the required codes can be found in the
respective documentation at www.leuze.com.
12.5.1.1 Cable-connected hand-held scanners on the MA 235i
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 235i, the voltage supply of the hand-held scanner (4.75 … 5.25VDC/
at 1A) 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 235i. This cable must
also be ordered separately.
In this example, triggering occurs by means of a trigger button on the hand-held scanner.
Notice!
When using third-party devices, check the pin assignment and interface settings without fail
and adjust them if necessary.

12.5.1.2 Wireless hand-held scanners on the MA 235i
All wireless 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 230VAC connection (socket) is usually necessary for the charging station. Here, a data
connection of the charging station is established with the MA 235i. 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 235i. 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.
12.5.2 Specific features in the operation of an RFM/RFI
When using the MA 235i 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.
If problems should occur during commissioning of the MA 235i you can refer to the following
table. Typical errors and their possible causes are described here as well as tips for their
elimination.

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.
For the BPS 8, BPS 300i and hand-held scanners, a number of specific features are to be
noted.
Notice!
Please note that Leuze only assumes liability for the function of Leuze products. When using
third-party devices, Leuze does not assume liability for the function of third-party devices!
16.1Standard setting, KONTURflex (S4 switch position 0)
This switch position can be used with almost all devices, since a data frame is transmitted
along with it if necessary. A 00h in the data range of the control is interpreted as the end of
a telegram/invalid, however.
The distance between two successive telegrams (without frame) must be more than 20ms
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.
