Operating modes
For fast commissioning, the MA 258
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 258
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, con-
figure 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.
