PROFINET address (S1)
A logical address can be assigned to the I/O module for communication with PROFINET using
a 10-bit DIP switch S1.

on on PROFINET functionality
on on on on on on on on DCP mode
The switch positions 9 and 10 guarantee the PROFINET functionality of the module and must
always be switched "on".
DCP mode
In this mode, there is no default device name.
The device name must be set using initialization and remains saved on the I/O module. It is first
deleted when the factory setting is restored, e.g. using STEP 7 (TIA Portal).
Default device names
The switch positions 1 to 8 define the default device name of the I/O module.
There are up to 128 default device names. If these default device names are used, there is no
need for initialization.
Note
The default device names cannot be reconfigured, for example with the TIA Portal "Assign
device name" function.
If you are connecting the I/O module to a SINUMERIK control as a PROFINET component,
make sure that this functionality is supported by the associated control.
