SBI interface (only
PS 416-CPU-300/-400)
The communication with the Suconet K stations or
data terminal units is carried out via the SBI interface
of the central unit. Transparent or Suconet K mode
can be set for the SBI interface (see Hardware
configuration), depending on the application at hand.
Suconet K mode
In the Suconet K mode the central unit is operated as
a station of a Suconet K line. The station type
(master/slave) is defined in the Sucosoft S 40
Topology Configurator. The central unit can also
connect expander racks when operating as a master.
You will find further information in the Suconet K
interface manual (AWB 27-1210-GB) or in the
relevant manuals for the remote expansion modules.
Transparent mode
This operating mode provides a serial interface for
the point-to-point communication with a data
terminal unit. The communication is carried out via
the COM function block which is integrated in the
central unit and can be called up via Sucosoft S40.
The signal level conversion for other interfaces must
be carried out with appropriate converters. The
UM 1.5 converter is available for an RS 485/RS 232
coupling. The addressing of the interface by the
software is described in section “Operation”.
