4.3.4.4 Addressing
In order to use the device in an AS-i network, it must have a unique address. The address is set to 0 in
the factory. This means that the device can be recognised as a "new device" by an AS-i master
(prerequisite for automatic address assignment by the master).
Course of action
• Ensure power supply of the AS interface via the yellow AS interface cable.
• Disconnect the AS interface master during addressing
• Set the address ≠ 0
• Do not doubly assign addresses
In many other cases, addressing is carried out using a normal addressing device for AS interface
slaves (example follows).
• Pepperl+Fuchs, VBP-HH1-V3.0-V1 (separate M12 connection for external power supply)
• IFM, AC1154 (battery operated addressing device)
Special conditions for the supply exclusively via the yellow cable
• Ensure voltage supply of the SK 1xxE-FDS-...-ASI, SK 1xxE-FDS-AUX, SK 1xxE-FDS-AXS, SK
1xxE-FDS-ASS device also via yellow AS-Interface cable (pay attention to current consumption of
control level of the device's SK 1xxE-FDS-...-ASI, SK 1xxE-FDS-ASS control level (450 mA))
• When using an addressing unit
– Do not use the internal voltage source of the addressing unit
– Battery-operated addressing units do not supply the required current and are therefore not
suitable
– Use addressing units with a separate 24 V DC connection for external voltage supply (example:
Pepperl+Fuchs, VBP-HH1-V3.0-V1)
The following lists options how to practically implement the addressing of the AS-i slave using an
addressing unit.
