Service interface
The service interface can be accessed once the MA
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.

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 9600 bd, 8N1 and STX, data, CR, LF.

Fieldbus systems
Various product variants of the MA
fieldbus systems such as PROFIBUS DP, PROFINET-IO, DeviceNet and Ethernet.
4.5.1
PROFIBUS DP
The MA
204i
a baud rate of max. 12 MBd. The functionality of the device is defined via parameter sets
which are clustered in modules. These modules are contained in a GSD file.
The MA
204i
features multiple M 12 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 7.2.
