3 Fast commissioning / operating principle
Notice!
Below you will find a short description for the initial commissioning of the PROFINET
gateway MA 248i. Detailed explanations for the listed points can be found throughout the
handbook.
3.1 Mounting
The gateway mounting plate MA 248i 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 248i 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 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 248i connections
Detailed information can be found in chapter 7.
Leuze electronic MA 248i 11
TNT 35/7-24V
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 248i 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 protection class IP 65.
Finally, close the housing of the MA 248i.
Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 248i, 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 (+24VDC model); the MA 248i starts up.
The PWR LED displays that it is ready for operation.
First, you need to assign its individual device name to the MA 248i. The PLC must communicate this device name to the participant during the "device naming". Further information
may be found below and in chapter "Step 6 – Configuration of the device name - naming
the device" on page 69.
12 MA 248i Leuze electronic
Fast commissioning / operating principle
3.5 Commissioning the MA 248i on the PROFINET
Complete the necessary steps for commissioning a Siemens-S7 control as described
below.
Further information regarding the individual commissioning steps is provided in see chapter
12.3 "Configuration steps for a Siemens Simatic S7 control".
3.5.1 Preparing the control system
In the first step, assign an IP address to the IO Controller (S7 PLC) and prepare the control
for a 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.
3.5.2 Installation of the GSD file
For the subsequent configuration of the IO devices, e.g., MA 248i, 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 PROFINET-IO Manager of your
control.
Leuze electronic MA 248i 13
TNT 35/7-24V
Fast commissioning / operating principle
3.5.3 Configuration
Configure the PROFINET-IO system with the HW Config of the SIMATIC Manager by
inserting the MA 248i into your project.
Figure 3.2: Assignment of the device names to IP addresses
Here, an IP address is assigned to a unique "device name".
3.5.4 Configuration of the modules
Now select a corresponding data module for the input and output area.
A number of different modules are available with various data lengths (4, 8, 12, 16,
20, 32 … 1024 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.
14 MA 248i Leuze electronic
Fast commissioning / operating principle
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 68.
3.5.5 Transfer of the configuration to the IO Controller
Transfer the PROFINET-IO configuration to the IO Controller (S7 PLC)
After the correct transfer to the IO Controller (S7 PLC), the PLC automatically carries out
the following activities:
• Check device names
• Assignment of the IP addresses that were configured in the HW Config to the
IO devices
• Establishment of a connection between the IO Controller and configured IO devices
• Cyclical data exchange
Notice!
Participants that have not been "named" cannot be contacted yet at this point in time!

TNT 35/7-24V
Fast commissioning / operating principle
3.5.6 Configuration of the device name - device naming
PROFINET-IO defines the "naming of the device" as the creation of a name-based relationship for a PROFINET-IO device.
Assigning the device names to the configured IO devices
Select the respective gateway MA 248i for the "device naming" based on its MAC
address.
The unique "device name" (which must match the participant in the HW Config) is then
assigned to this participant.
Notice!
Multiple MA 248i can be distinguished by the MAC addresses displayed. The MAC address
may be found on the name plate of the respective bar code scanner.
Figure 3.3: Assigning the device names to the configured IO devices

MAC address - IP address -individual device name
At this point, please assign an IP address (suggested by the PLC), a subnet mask and, if
required, a router address, and assign this data to the named participant ("device name").
Figure 3.4: MAC address - IP address -individual device name
From now on, and when programming, only the unique "device name" (max. 255 characters)
is used.
3.5.7 Device name check
After completing the configuration phase, recheck the "device names" that have been
assigned. Please ensure that these names are unique and that all participants are located
in the same subnet.

4.1 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, …) 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.
4.2 Characteristics of the connector units
A special characteristic of the MA 248i device family are three function modes:
1. Transparent mode
In this function mode, the MA 248i 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 248i 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 248i 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 248i and connected there with the PCB connectors.
The MA 248i 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
4.4 Operating modes
For fast commissioning, the MA 248i 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 248i 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.
Figure 4.2: Service-switch switch positions
Notice!
If the service switch is on one of the service settings, the SF 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.

4.5 Fieldbus systems
Various product variants of the MA 2xxi series are available for connecting to different
fieldbus systems such as PROFIBUS DP, PROFINET-IO, DeviceNet and Ethernet.
Device description
4.5.1 PROFINET-IO
The MA 248i is designed as a PROFINET-IO device (acc. to IEEE 802.3). It supports a transmission rate of up to 100 Mbit/s (100Base TX), full duplex, as well as auto-negotiation and
auto-crossover.
The functionality of the device is defined via parameter sets which are clustered in modules.
These modules are contained in a GSDML file.
Each MA 248i is sealed with a unique MAC-ID. This information is used to assign a unique,
plant-specific device name ("NameOfStation") to the device via the "Discovery and Configuration Protocol (DCP)". When configuring a PROFINET-IO system, the assignment of the
device names to the configured IO devices creates a name-based relationship for the participating IO devices ("device naming"). Further information can be found in section "Step 6 –
Configuration of the device name - naming the device" on page 69.
The MA 248i features multiple M12 connectors / sockets for the electrical connection of the
supply voltage, the interface and the switching inputs and outputs. Additional information
Leuze electronic MA 248i 21
on the electrical connection can be found in chapter 7.2.

PROFINET-IO – star topology
The MA 248i can be operated as a single device (standalone) with individual device name
in a star topology. The PLC must communicate this device name to the participant during
the "device naming".
Figure 4.4: PROFINET-IO in a star topology
PROFINET-IO – linear topology
The innovative further development of the MA 248i with integrated switch functionality offers
the option of connecting multiple connector units of type MA 248i to one another without
direct connection to a switch. In addition to the classic "star topology", a "linear topology"
is thus also possible.
Leuze electronic MA 248i 23
Figure 4.5: PROFINET-IO in a linear topology
Each participant in this network requires its own unique device name that is assigned by
the PLC during the "device naming". For specific information, please refer to chapter "Step
6 – Configuration of the device name - naming the device" on page 69.
The maximum length of a segment (connection from the hub to the last participant) is limited
to 100m.
