Notice!
Below you will find a short description for the initial commissioning of the Ethernet
gateway MA 208i. Detailed explanations for the listed points can be found throughout the
handbook.
3.1 Mounting
The gateway mounting plate MA 208ican 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 208ishould 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 208iand guide the corresponding device cable (see chapter 14.6, 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.
Finally, close the housing of the MA 208i.
Attention!
Only then may the supply voltage be applied.

Upon startup of the MA 208i, 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.
3.3.2 Connecting the power supply and the bus cable
Ideally, use the ready-made cables listed in chapter 14.4.3 to connect the gateway to the
power supply via the PWR IN connection.
The ready-made cables listed in chapter 14.5.4 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 208istarts up.

The PWR LED displays that it is ready for operation.

12 MA 208iLeuze electronic
3.5 MA 208ion Ethernet
Setting the communication parameters
With the communication parameters, you determine how data is exchanged between
MA 208iand host system, monitor PCs etc.
The communication parameters are independent of the topology in which the MA 208iis
operated (see "Ethernet" on page 18).
On delivery from firmware 1.1.0.0, automatic address assignment is deactivated via DHCP
and a permanent IP address is set:
Device address: 192.168.61.100.
Net mask: 255.255.255.0
The setting can be adapted via Leuze configuration software BCL-Config, BPS-Config or
RF-Config. In these tools, the MA 208ihas been created as a device to enable setting of
parameters in the usual way via the service interface.
3.5.1 Manually setting the IP address
If the IP address of the devices should be permanently set on your system, proceed as
follows:
Have the network administrator specify the data for IP address, net mask and gateway
address of the MA 208i.
Select the connected device via the device selection switch.
Apply the supply voltage +18 … 30VDC (typ. +24VDC); the MA 208istarts up.
Now switch the service switch to "MA".
Notice!
The service switch must be in switch position "MA" here so that the MA 208ican be
addressed via the service interface.
Connect the serial RS 232 Sub-D interface of the MA 208ito the serial interface of your
PC.
Make the necessary settings in the configuration window.

3.5.2 Ethernet host communication
The Ethernet host communication enables the configuration of connections to an external
host system. Both UDP as well as TCP/IP (in either client or server mode) can be used. The
connection-free UDP protocol is used primarily to transfer process data to the host (monitor
operation). The connection-oriented TCP/IP protocol can also be used to transfer
commands from the host to the device. With this connection, the data is backed up by the
TCP/IP protocol itself.
If you would like to use the TCP/IP protocol, you must also define whether the MA 208iis
to operate as a TCP client or as a TCP server.
Contact your network administrator to determine which communication protocol is used.

Fast commissioning / operating principle
14 MA 208iLeuze electronic
3.5.3 TCP/IP
Set the TCP/IP mode of the MA 208i.
In TCP client mode, the MA 208iactively establishes the connection to the primary host
system (PC / PLC as server). The MA 208irequires from the user the IP address of the server
(host system) and the port number on which the server (host system) accepts a connection.
In this case, the MA 208idetermines when and with whom a connection is established!
With a MA 208ias TCP client, set the following values:
• IP address of the TCP server (normally the PLC/host computer)
• Port number of the TCP server
• Optional: Timeout for the wait time for an answer from the server
• Optional: Repetition time for renewed communication attempt following a timeout
In TCP server mode, the primary host system (PC / PLC) actively establishes the connec-
tion and the connected MA 208iwaits for the connection to be set up. The TCP/IP stack
requires information from the user regarding the local port of the MA 208i(port number) on
which the connection requests of a client application (host system) are to be accepted. If
there is a connection request and a connection is established by the primary host system
(PC / PLC as client), the MA 208i(server mode) accepts the connection. Data can then be
sent and received.
With a MA 208ias TCP server, also set the following values:
• Port number for the communication of the MA 208iwith the TCP client
The corresponding adjustment options can be found in the configuration tool.
3.5.4 UDP
The MA 208irequires from the user the IP address and the port number of the communi-
cation partner. Correspondingly, the host system (PC / PLC) now also requires the set
IP address of the MA 208iand the selected port number. By assigning these parameters,
a socket is formed via which the data can be sent and received.
Set the following values:
• IP address of the communication partner
• Port number of the communication partner
The corresponding adjustment options can be found in the configuration tool.

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, AMS 200) in the
respective fieldbus. The MA 2xxigateways are intended for use in industrial environments
with a high protection class. Various device versions are available for the conventional field-
buses. With a stored parameter structure for the connectable RS 232 devices, commis-
sioning could hardly be simpler.
4.2 Characteristics of the connector units
A special characteristic of the MA 208idevice family are three function modes:
1. Transparent mode
In this function mode, the MA 208ifunctions 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 datafrom the input memory of the
PLC at the right time, as it isotherwise 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.
Thisfunction mode ishelpful, for example, for very long telegramsor when one or
more codeswith long code lengthsare read.
Notice!
The Collective mode is not available for the MA 208i. Due to a variable telegram
length, data can always be transmitted in its entirety independent of its length. It is not
necessary to transfer data in blocks.
3. Command mode
With thisspecial operating mode, it ispossible to use the first bytesof the datarange
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 208imodular 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 208iwhere 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, VR) to the fieldbus
The cable of the respective Leuze device is guided through cable bushings with PG cable
glands into the MA 208iand connected there with the PCB connectors.
The MA 208iis 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 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 208ioffers an additional operating mode, the "Service
mode", in addition to the "Standard mode". 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 ’v’ command.
Figure 4.2: 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.

Device description
18MA 208iLeuze electronic
Service interface
The service interface can be accessed once the MA 208ihousing 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 and Ethernet.
4.5.1 Ethernet
The MA 208iis designed as an Ethernet device (acc. to IEEE 802.3) with a standard baud
rate of 10/100 Mbit. A fixed MAC ID is assigned to each MA 208iby the manufacturer; this
ID cannot be changed.
The MA 208iautomatically supports the transmission rates of 10 Mbit/s (10Base T) and
100 Mbit/s (10Base TX), as well as auto-negotiation and auto-crossover.
The MA 208ifeatures multiple M12 connectors / sockets for the electrical connection of the
