SYSTEM DESCRIPTION
DIP switches
The PROFIBUS address and the behaviour of the PROFIBUS terminal can be adjusted by using the 10 x
DIP switch.
The relevance of DIP switches for the PROFIBUS bus terminal from serial number 37344 onwards can be
ascertained in the following table.

Configuration of the 10-fold DIP switch
Diagnosis LEDs directly on the station
NOTE
You will find a detailed illustration of individual functions under field bus node PPROFIBUS-
DPV1 / Description of field bus node.
DIP switch Meaning
1 ... 7 PROFIBUS address in binary display ( 0 to 127 in decimal display)
Switch 1 establishes the least significant bit (LSB) (2
0
)
Switch 7 establishes the highest significant bit (HSB) (2
6
)
8 Inline station operating mode:
ON: New mode with DPV1 support, security values and parameterization;
OFF: Compatible mode (to PROFIBUS bus terminal up to serial number 37343)
9 ... 10 When an LWL plug connector is used, both switches are set to ON to allow for the
increased current requirements of the LWL connector. The interface power supply is
then no longer isolated in potential.
Abb-rev Colour Meaning Explanation
UM green Main supply
Supply voltage in main circuit for field bus nodes, logic supply and
interrfaces present.
US green Segment supply
Supply voltage present in segment circuit.
BF red Bus Fault
No data exchange with master.
FS red Failure Select
Select function of LED FN:
FS lights: FNshow the error type.
FS does not light: FN show the error number.
FN red Failure Number
The number of flashes indicates the error tyoe of error number,
depending on whether FS lights or not.
