This is accomplished by transmitting the data from the DEV via an RS 232 (V.24) interface
to the MA 235iwhere 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.

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.
3.1 Mounting
The gateway mounting plate MA 235ican be mounted in two different ways:
• using four threaded holes (M6) or
• using two M8x6 screws on the two lateral grooves.
3.2 Device arrangement and selection of the mounting location
Ideally, the MA 235ishould 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.
3.3 Electrical connection
The devices from the MA 2xxifamily 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.

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 235iand 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 235iis 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 235ivia the baud rate selector switch. Only if the baud rates are
the same is communication with the MA 235ipossible.
Set the baud rate of the gateway via the S3 rotary switch to the value defined in the control.
Figure 3.3: Rotary switch for setting baud rate
Finally, close the housing of the MA 235i.
Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 235i, the device selection switch is queried and the gateway auto-
matically 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 connec-
tion.

3.3.2 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.
3.4 Starting the device
Apply the supply voltage +18 … 30VDC (typ. +24VDC); the MA 235istarts up.
The PWR LED displays that it is ready for operation.

Install the EDS file corresponding to the MA 235iin your planning tool/the control.
Notice!
You can find the EDS file at: www.leuze.com
The MA 235iis 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 235ivia the
S1 and S2 address switches. Only if the addresses are the same between the MA 235iand
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 235iparameters 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 235ivia the S3 baud rate selector switch.
Only if the baud rates are the same is communication with the MA 235ipossible.
Detailed information can be found in chapter 12.

4 Device description
4.1 General Information to the connector units
The modular interfacing unit of the MA 2xxifamily is a versatile gateway for integrating Leuze
RS 232 devices (e.g., BCL 22 bar code readers, RFID devices, RFM 32, …) into the respec-
tive fieldbus. The MA 2xxigateways 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 235idevice family are three function modes:
1. Transparent mode
In this function mode, the MA 235ifunctions as a pure gateway with automatic com-
munication 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 pro-
grammed 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 pre-
defined via the device selection switch, see chapter 16 "Specifications for Leuze end
devices".

4.3 Device construction
The MA 235imodular 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 235iwhere a module
converts it into the fieldbus format. The data format of the RS 232 interface corresponds to
the standard Leuze data format.
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 235iand connected there with the PCB connectors.
The MA 235iis 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 protec-
tion against contamination.
With the help of adapter cables with Sub-D 9 or open cable end, other RS 232 devices can
also be connected.

4.4 Operating modes
For fast commissioning, the MA 235ioffers 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 235iand 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, con-
figure 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.

Device description
Leuze electronic MA 235i17
TNT 35/7-24V
Service interface
The service interface can be accessed once the MA 235ihousing 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.
Figure 4.3: Connecting the service interface to a PC/terminal
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.
4.5 Fieldbus systems
Various product variants of the MA 2xxiseries are available for connecting to different
fieldbus systems such as PROFIBUS DP, PROFINET-IO, DeviceNet, CANopen and Ethernet
or EtherCAT.

Device description
18 MA 235iLeuze electronic
The CAN bus is a serial 2-wire bus system to which all participants are connected in paral-
lel (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 235iis 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 terminat-
ing 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 sig-
nals are present virtually simultaneously at all nodes/participants. Therefore, the cable
length of the trunk cable must be adapted to the baud rate.
Stub cables (drop lines)
If possible, stub cables should be avoided because they cause signal reflections as a mat-
ter of principle. Generally, the reflections caused by stub cables are not critical, however, if
the following stub cable lengths are not exceeded.
Attention!
Stub cables must not be fitted with terminating resistors. If the MA 235iis integrated into a
stub cable, the M12 bus OUT connection must not be terminated.
