3 Fast commissioning / operating principle
3.1 Mounting
The gateway mounting plate MA 208 i can 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 208 i 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.
3.3 Electrical connection
The devices from the MA 2xx i 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 depends 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 208
i connections
Detailed information can be found in Chapter 7.
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 208
i
and lead the corresponding device cable (see Chapter 14.6) 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 degree of
protection IP 65.
Finally, close the housing of the MA 208
i .
Connecting the 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.

Leuze electronic GmbH + Co. KG MA 208 i 11
3.3.2 Connecting the power supply and the bus cable
Ideally, use the preassembled cables listed in Chapter 14.4.3 to connect the gateway to the power sup-
ply via the PWR IN connection.
The preassembled cables listed in Chapter 14.5.4 are preferred for connecting the gateway to the field-
bus 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
Connect the +18 … 30VDC supply voltage (typ. +24VDC), the MA 208 i starts up.
The PWR LED displays that it is ready for operation.
3.5 MA 208 i on Ethernet
Setting the communication parameters
With the communication parameters, you determine how data is exchanged between MA 208
i and host
system, monitor PCs etc.
The communication parameters are independent of the topology in which the MA 208
i is operated (see
"Ethernet" on page 16).
On delivery from firmware 1.1.0.0, automatic address assignment is deactivated via DHCP and a perma-
nent 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 208
i has been created as a device to enable setting of parameters in the usual way
via the service interface.
3.5.1 Manual configuration of 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 208
i .
Select the connected device via the device selection switch.
Connect the +18 … 30VDC supply voltage (typ. +24VDC), the MA 208
i starts up.
Now switch the service switch to "MA".
Connect the serial RS 232 Sub-D interface of the MA 208
i to the serial interface of your PC.
Make the necessary settings in the configuration window.
NOTE
The service switch must be in switch position "MA" here so that the MA 208
i can be addressed
via the service interface.

Figure 3.2: Setting the parameters manually
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 208
i is to operate as a
TCP client or as a TCP server.
Contact your network administrator to determine which communication protocol is used.
3.5.3 TCP/IP
Set the TCP/IP mode of the MA 208
i .
In TCP client mode, the MA 208
i actively establishes the connection to the primary host system (PC / PLC
as server). The MA 208
i requires 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 208
i determines
when and with whom a connection is established!
With a MA 208
i as 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 connection and the
connected MA 208
i waits for the connection to be set up. The TCP/IP stack requires information from the
user regarding the local port of the MA 208
i (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 estab-
lished by the primary host system (PC / PLC as client), the MA 208
i (server mode) accepts the connection.
Data can then be sent and received.
With a MA 208
i as TCP server, also set the following values:
• Port number for the communication of the MA 208
i with the TCP client
The corresponding adjustment options can be found in the configuration tool.

Leuze electronic GmbH + Co. KG MA 208 i 13
3.5.4 UDP
The MA 208
i requires from the user the IP address and the port number of the communication partner.
Correspondingly, the host system (PC / PLC) now also requires the set IP address of the MA 208
i and 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.

4wDevice description
4.1 General information to the connection units
The modular connection unit of the MA 2xx i 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 2xx
i gateways are intended for use in industrial environments with a high degree of protection. 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 connection units
A special characteristic of the MA 208 i device family are three function modes:
1. Transparent Mode
In this function mode, the MA 208
i 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 pur-
pose, device-dependent commands (so-called online commands) are predefined via the device
selection switch, see chapter 16 "Specifications for Leuze end devices".
4.3 Device construction
The MA 208 i modular connection unit is used for connecting 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 208
i where a module converts it into the fieldbus format. The data
format of the RS 232 interface corresponds to the standard Leuze data format.
NOTE
The Collective mode is not available for the MA 208
i . 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.

Leuze electronic GmbH + Co. KG MA 208 i 15
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 208
i and connected there with the PCB connectors.
The MA 208
i 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 pin strips. 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.
4.4 Operating modes
For fast commissioning, the MA 208 i offers 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, 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 ’v’ com-
mand.

Service interface
The service interface can be accessed once the MA 208
i 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.
Figure 4.3: Connecting the service interface to a PC/terminal
4.5 Fieldbus systems
Various product variants of the MA 2xx i series are available for connecting to different fieldbus systems
such as PROFIBUS DP, PROFINET-IO, DeviceNet and Ethernet or EtherCAT.
4.5.1 Ethernet
The MA 208
i is 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 208
i by the manufacturer; this ID cannot be changed.
The MA 208
i automatically 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 208
i features multiple M12 connectors / sockets for the electrical connection of the supply voltage,
the interface and the switching inputs and outputs. Additional information on the electrical connection can
be found in chapter 7.
The MA 208
i supports the following protocols and services:
• TCP / IP (client/server)
•UDP
•DHCP
•ARP
•PING
For communication with the superior host system, the corresponding TCP/IP protocol (client/server mode)
or UDP must be selected.
Further information on commissioning can be found in chapter 12.
Ethernet – star topology
The MA 208
i can be operated as a single device (standalone) in an Ethernet star topology with individual
IP address.
The address is either set permanently via the RS 232 interface or assigned dynamically via a DHCP
server.
NOTE
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.
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.

Ethernet – linear topology
The innovative further development of the MA 208
i with integrated switch functionality offers the option of
connecting multiple gateways of type MA 208
i to one another without direct connection to a switch. In addi-
tion to the classic "star topology", a "linear topology" is thus also possible.
Figure 4.5: Ethernet in a linear topology
Each participant in this network requires its own unique IP address, which must be assigned to it via the
RS 232 interface. Alternatively, the DHCP procedure can be used.
The maximum length of a segment (connection from the hub to the last participant) is limited to 100m.
