MA 258
i
Leuze electronic
Service interface
The service interface can be accessed once the MA 258
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.

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.

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/IP
The MA 258
i
is designed as an EtherNet/IP device (acc. to IEEE 802.3) with a standard baud
rate of 10/100 Mbit. The functionality of the device is defined via parameter sets which are
clustered in objects, classes and instances. These objects … are contained in an EDS file
which, depending on the version of the control software, can be used to configure and inte-
grate the MA into the system. PLC software RSLogix 5000 from Rockwell offers EDS
support for EtherNet/IP from software version 20.00 and up. A fixed MAC ID is assigned to
each MA 258
i
by the manufacturer; this ID cannot be changed.
The MA 258
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 258
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.
