6.15 Bus communication
The pump is supplied with an integrated

"Activate
Genibus?" prompt is displayed. After confirmation,
the ’Bus’ submenu appears in the ’Setup’ menu.

The corresponding symbol appears in the ’Activated
functions’ area in the ’Operation’ menu.
The pump can also be integrated into a Profibus DP
network using the additional E-box module
(retrofitting possible).
The bus communication enables remote monitoring
and setting of the pump via a fieldbus system. The
accompanying fieldbus documentation and the
Profibus GSD file can be downloaded from the
Internet.
