Note
If two addresses are assigned for one valve location, the
following applies:
– lower-value address: pilot solenoid 14
– higher-value address: pilot solenoid 12
Address assignment on the Interbus
The address assignment (processing data assignment) of the
inputs and outputs of a CPX terminal on the Interbus depends
above all on the Interbus module and on the control system
used.
Caution
There are different address assignments on the Interbus.
The reason for this is the assignment of the processing
data within the Interbus module.
When assigning the addresses, note the position of the
•
high and low bytes, as the position of these bytes may
be swapped in conjunction with some control systems.
You can then avoid faults in addressing the inputs/out-
puts.
Further details on addressing can be found in the manuals for
your controller and for the Interbus module.
The following examples provide basic information on the
different address assignments and the positions of the low
byte (n) and the high byte (n+1) with various controllers.
There are two modes:
– In the Siemens mode the lower-value input or output byte
(byte n) is mapped on inputs or outputs 0 ... 7, byte n+1
on the next inputs or outputs (8 ... 15) etc.
