– In the Standard mode the lower-value input or output
byte (byte n) is mapped on inputs or outputs 8 ... 15,
byte n+1 on the inputs or outputs 0 ... 7.
This allocation also applies to the bytes of diagnostics
M2 ... M4.
In section 2.1.8 you will find instructions on addressing with
the CMD software (processing data assignment) and on
modifying the position of the low and high bytes ("byte swap").
Note
The byte swap can either be set via DIL switch 1.3 or with
the help of the CMD software. If the byte swap is set via
DIL switch and CMD, then the settings override each other!
Examples for the address assignment of the CPX
terminal
The following examples show the assignment of the input and
output bytes to the individual modules. In the examples the
following applies:
– Configured input address:
Configured output address:
– The address assignment is represented both in the
Siemens mode and in the Standard mode.
The address assignment within the individual I/O modules
can be found in the manual for the I/O modules.
The address assignment within the pneumatic modules can
be found in the manual for the valve terminal pneumatics.
