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, 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
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 255idevice family are three function modes:
1. Transparent mode
In this function mode, the MA 255ifunctions 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 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
programmed on the PLC.
Thisfunction mode ishelpful, for example, for very long telegramsor when one or
more codeswith long code lengthsare read.
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
predefined via the device selection switch, see chapter 16 "Specifications for Leuze
end devices".

4.3 Device construction
The MA 255imodular 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 255iwhere 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 devices (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 255iand connected there with the PCB connectors.
The MA 255iis 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
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 255ioffers 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 255iand 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 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 255iLeuze electronic
Service interface
The service interface can be accessed once the MA 255ihousing 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 DeviceNet
