Fieldbus interface
For connection to external control devices, like PLCs,
typically the third serial interface, "fieldbus interface"
is used.
Several fieldbus protocol specific adapters are avail-
able as options for the DCS 400. The following de-
scription is an overview. Detailed information is avail-
able from the specific adapter descriptions.
Characteristics:
• Fieldbus adapter is mounted on external mounting
rail
• Power supply from DCS 400 (built-in)
• Connection between adapter and DCS 400 is
optical cable
• DCS 400 automatically detects the connected
fieldbus type
• Therefore, the user specific paramter settings are
drastically reduced
User specific parameters like e.g. station addresses
or Modbus settings are only set once, during the
commissioning.
Short Commissioning Guide
• Switch
Off
DCS 400 electronics power supply.
• Mount fieldbus adapter on mounting rail.
• Connect adapter to power supply (X8).
• Connect optical cables from adapter to DCS 400
(V800).
• Connect fieldbus cable to fieldbus adapter.
• Switch
On
DCS 400 electronics power supply.
• Wait approximately 10 s.
During this time an initialization is done between
fieldbus adapter and DCS 400. Most of fieldbus
parameter are pre-defined by the fieldbus adapt-
er automatically after that procedure.
• Set Fieldbus Par 1 (8.01) (Module Type) = Field-
bus.
• Set user specific parameters. For detailed descrip-
tion, refer to the description which is following the
fieldbus adapaters.
• Wait 10 s.
• Switch
Off and On
again the electronics power
supply, in order to re-initialize the user specific
parameter settings, which have been changed to
include the serial communications.
The communication parameters
Cmd Location
(2.02)
,
Comm Fault Mode (2.07)
and
Comm Fault Time
(2.08)
need to be set manually, for the purpose of
communication supervision. See chapter about
com-
munication parameters
earlier in this document.
