4.3.4. Profibus - RS485 bus connection
Profibus
CAN Bus connection is provided by 9-
pin D-SUB connector (female) that is
integrated in the front panel.
Connector-housing: shield / functional
earth.
Any requested Profibus looping can be
proceeded in the attachment connector
itself (not included in the
delivery).Corresponding connectors are
available in specialized shops. It is
imperative to avoid stub lines in cabling
but to proceed any Profibus loops
directly at the device itself.

RS485 Bus
RS485 Bus connection and power
supply is provided by 2 x 4-pin screw
terminal connectors
UB:12..24 VDC, ripple 5%, 40 mA
Supplementary consumption of each
spindle position display (with no
motive drive): approx. 30 mA.
It is possible to connect up to 32
multicon SPAs to the RS485 bus in
any combination.
The bus terminator is firmly installed
in the gateway. That’s why the
gateway always has to be at one of
the two ends of an RS485 string. The
respectively remaining end has to
provide a bus terminating connector
at the final SPA.
