04 IP 
CONFIGURATION
Sets the method for configuring the IP 
address, subnet mask and gateway address 
for the module.
In a PROFINET IO network, the master 
controller has a Duplicate Address Detection 
mechanism.

IP configuration
0 = Static IP Configuration will be obtained from 
parameters 05…13 or from the PLC via DCP. 
The DCP protocol allows the master controller 
to find every PROFINET IO device on a 
subnet. When the adapter module is 
configured for the PROFINET IO protocol, the 
IP address is transferred to the PROFINET IO 
communication stack.
If there is a need to change the IP address 
configured via DCP, it should be done with a 
DCP tool, such as Siemens Step7. If some of 
the other methods are used to change the IP 
address, the module must be restarted to 
enable any changes. 
1 = Dyn IP DHCP Configuration will be obtained via DHCP.
