Description of functions
The MA 255
i
modular interfacing unit is used to connect Leuze devices directly to the
fieldbus.

2D code reader:
LSIS 122, LSIS 4x2i
Hand-held scanner
ITxxxx, HFU/HFM
RFID read-write devices:
RFM 12, 32, 62 & RFI 32, RFU 61, 81
Bar code positioning system:
BPS 8
Distance measurement device:
AMS 200
Optical distance sensors:
ODSL 9, ODSL 30, ODSL 96B
Measuring light curtain:
KONTURflex to Quattro-RSX/M12
MultiNet master connection box:
MA 3x
Additional RS 232 devices:
Scales, third-party devices
This is accomplished by transmitting the data from the DEV via an RS 232 (V.24) interface
to the MA 255
i
where a module converts it into the DeviceNet format. The data format on
the RS 232 interface corresponds to the Leuze standard data format (9600 bd, 8N1 and STX,
data, CR, LF).
The integration of the EDS file in the hardware manager of the PLC is necessary to ensure
the correct function of the MA 255
i
.
The corresponding Leuze devices are selected using a rotary code switch on the circuit
board of the connector unit. Many additional RS 232 devices can be connected through a
universal position.
