If a valve location remains unused (blanking plate)
or if a digital input/output is not connected, the
appropriate address is still assigned.
The diagram below shows the address assign-
ment with mixed fitting.
Remarks on the diagram
•
If single solenoid valves are fitted onto D-
type sub-base modules, four addresses will
be assigned for solenoid valve coils; the hig-
her address in each case then remains
unused (see address 3).
•
If unused valve locations are covered with
blanking plates, the addresses are still as-
signed (see addresses 12, 13).
•
Due to the 4-bit orientated addressing of the
modular valve terminal, the address of the
last location is always rounded up to four full
bits (unless the equipment fitted already uses
the full four bits). This may mean that two
addresses cannot be used (see addresses
14, 15).
