• 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 238 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.

3.5 MA 238 i on EtherCAT
3.5.1 Device description file
For EtherCAT, all process data and parameters are described in objects. The compilation of all process
data and parameters of the gateway - the object directory - is stored in a so-called ESI file (EtherCAT Slave
Information).
The ESI file contains all objects with index, sub-index, name, data type, default value, minimum and
maximum, and access possibilities. That means the ESI file describes the entire functionality of the
MA 238
i .
The ESI file has the name MA 238
i .xml and is available for download on the Leuze home page.
Vendor ID for the MA 238
i
The Vendor ID assigned by Leuze for the MA 238 i is 121h = 289d.
Detailed information on the device description file and the object directory can be found in Chapter 12.5.3.
3.5.2 Device profile
The device profile describes the application parameters and the functional behavior of the MA 238
i . For
EtherCAT, one does not specify individual device profiles for device classes. Instead, simple interfaces for
existing device profiles are provided.
3.5.3 Starting the MA 238
i in the EtherCAT system
As is common for EtherCAT, the gateway runs through different states when starting up: "INIT", "PREOP",
"SAFEOP" and "OPERATIONAL".
Detailed information can be found in Chapter 12.4.

4 Device 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 238 i device family are three function modes:
1. Transparent Mode
In this function mode, the MA 238
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 238 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 238
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.
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 238
i and connected there with the PCB connectors.
The MA 238
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.

Leuze electronic GmbH + Co. KG MA 238 i 13
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 238 i 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 238
i 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
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.

Leuze electronic GmbH + Co. KG MA 238 i 14
Service interface
The service interface can be accessed once the MA 238
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 EtherCAT
General information on EtherCAT
EtherCAT is an Ethernet-based fieldbus initiated by the Beckhoff corporation. The EtherCAT Technology
Group (ETG) is the official standardization partner of the IEC working groups.
EtherCAT has been an IEC standard since 2005.
• IEC 61158: Protocols and services
• IEC 61784-2: Communication profiles for the specific device classes
All EtherCAT-specific communication mechanisms are described in detail in the standards mentioned
above. This technical description will describe parts of the IEC standard if this assists general under-
standing.
EtherCAT topology
EtherCAT permits a multitude of topologies such as line, tree, ring, star and combinations of these. The
bus or line structure known from the fieldbuses is thus also available for EtherCAT.
Telegrams are sent on a wire pair in the "processing direction" from the master to the slave. The EtherCAT
device processes the frames only in this direction and passes them on to the subsequent device until the
telegram has passed through all devices. The last device sends the telegram back to the master on the
second wire pair in the cable in the "forward direction". Here, the EtherCAT always forms a logical ring
structure regardless of the topology installed.
From an Ethernet point of view, an EtherCAT bus segment is nothing more than a single, large Ethernet
participant which sends and receives Ethernet telegrams. Within the "participant", however, there is a
multitude of EtherCAT slaves rather than one single Ethernet controller with a downstream micro-
processor.
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.
