Setting the bus addresses
Connecting the programming device
O
Make sure the system part is not under pressure or voltage.
O
Unplug the yellow AS-i cable from the
X7A
connection to disconnect
the bus coupler from the AS bus line.
O
Connect your programming device (see accessories) to the
X7A
socket.
O
Alternatively, perform programming with the PLC via the fieldbus. For more details, refer to
the manuals for your PLC or the controller used.
Activating bus slaves
O
If you have not already done so, loosen the cover screw above DIP switch
S5
on the back side of the product.
O
Before addressing, move only
one
of the four
S5
switches on the back side
of the bus coupler to the
ON
position to activate only one bus slave.

NOTICE
Disconnecting plugs while under voltage will destroy the electronic components of the
valve system!
Large differences in potential occur when disconnecting plugs under voltage, which can
destroy the valve system.
O
Make sure the relevant system component is not under voltage before disconnecting
plugs and/or connecting a programming device.
During addressing, only one bus slave may be activate, i.e. only one DIP switch
S5
may
be in the
ON
position.

Addressing
O
Assign the bus addresses separately, one after another.
O
Assign two valid bus addresses if using the variant with 8 outputs and assign
four valid bus addresses if using the variant with 16 outputs.
Valid addresses
Valid addresses range from 1 to 31.
Invalid addresses
A/B addresses 1 to 62 are invalid.
O
See the following table for bus slave address coding.
O
Activate the bus slave.
O
Position the cover screw on the
S5
switch.
O
Remove the programming cable and connect the AS bus line.
O
Connect the power supply.
Your bus address setting is taken over.
