9.4.3
Termination (PROFIBUS)
If the Gateway is operated as the first or last physical device in the PROFIBUS DP, there must be
a bus termination at this Gateway. In order to do this, either a bus terminating resistor must be
activated in the connector or the resistor (220
) integrated in the Gateway must be activated. In
order to do this, slide the slide switch to position ON. In all other cases, the slide switch must
remain in position OFF. Please refer to the general PROFIBUS literature for further information
on the subject of bus termination.
Note: To activate or deactivate the bus termination, please remove the bus-connector and care-
fully set the switch to the desired position.
9.4.4
Rotary coding switches High + Low (PROFIBUS-ID)
With these two switches the Gateway’s PROFIBUS-ID (00... 7D) is set in hexadecimal notation.
Please refer to the Annex for a conversion table from decimal to hexadecimal. This value is read
in only once when the Gateway is activated.The value can also be read-out or analyzed through
the Script command "
Get (FieldbusID, LongTemp)
".
See also chapter 16.6.
9.4.5
CANopen termination
If the Gateway is operated as the first or last physical device in the CANopen
®
, there must be a
bus termination at this Gateway. In order to do this, either a bus terminating resistor must be acti-
vated in the connector or the resistor (120
) integrated in the Gateway must be activated. In
order to do this, slide the slide switch to position ON. In all other cases, the slide switch must
remain in position OFF. Please refer to the general Fieldbus literature for further information on
the subject of bus termination.
