Changing the addressing schematic

The selected addressing schematic determines the principle according to which the I/O
addresses of the telegrams are assigned by drive objects and influences the address range
that is available for other purposes.
This addressing schematic is thus valid for the SINAMICS Integrated of the NCU as well as
all NX modules. The addressing schematic is also assigned to NX modules that were
connected retrospectively.
You can choose between two different I/O addressing schematics:
● Standard I/O addressing schematic
– Addressing scheme, as known from the SINUMERIK Toolbox for STEP 7 V5.5.
– The available address range for diagnostic addresses or additional peripherals is
– The I/O addresses of the telegrams are assigned in the middle of the address range
● I/O addressing schematic optimized for I/O address extension
– Larger, coherent address range for diagnostic addresses or additional peripherals at
– The telegram I/O addresses are assigned in descending order from the end of the
