When the power supply is switched on, the valve terminal
automatically recognizes all available pneumatic modules
and digital input/output modules and assigns the appropri-
ate addresses. If a valve location is not used (cover plate) or if
an input/output is not connected, the relevant address will
still be assigned. The diagram below shows the address as-
signment as an example.

Round up
Fig. 4/2: Address assignment of a valve terminal with digital I/Os (example type 03)
Remarks on the diagram
– If single-solenoid valves are fitted onto double-solenoid
sub-bases of valve terminal type 03 (MIDI/MAXI), four
addresses will be reserved for valve solenoid coils; the
higher address in each case will then remain unused (see
address 3 or Fig. 4/1).
– if unused valve locations are fitted with cover plates, the
addresses will still be assigned (see addresses 12, 13).
