Assigning the IP address and the name 
 
Note 
Naming devices 
ST (Structured Text) conventions must be satisfied for the name assignment of IO devices in 
PROFINET (SINAMICS components). The names must be unique within PROFINET. 
 
-" and "." are not permitted in the name of an IO device. 
"Accessible nodes" function
 
Use the STARTER to assign an IP address and a name to the PROFINET interface. 
●  Connect the direct Ethernet cable from the PG/PC to the PROFINET interface. 
●  Switch on the Control Unit. 
●  Open STARTER. 
●  A search is performed for available nodes in PROFINET via Project -> Accessible nodes 
or the "Accessible nodes" button. 
●  The SINAMICS drive object is detected and displayed as a bus node with IP address 
0.0.0.0 and without a name. 
●  Mark the bus node entry and select the displayed menu item "Edit Ethernet node" with 
the right mouse button. 
●  In the following "Edit Ethernet node" screen, enter the device name for the PROFINET 
interface and click the "Assign name" button. Enter the IP address (e.g. 169.254.11.22) in 
the IP configuration and specify the subnet screen (e.g. 255.255.0.0). Then click the 
"Assign IP configuration" button. Close the screen. 
●  The "Update (F5)" button displays the IP address and name in the entry for the bus node. 
If not, close the "Accessible nodes" screen and perform another search for accessible 
nodes. 
●  If the PROFINET interface is displayed as bus node, mark the entry and click the 
"Accept" button. 
●  The SINAMICS drive is displayed as a drive object in the project tree. 
●  Further configurations can be performed for the drive object. 
●  Click "Connect to target system" and load the project to the Control Unit's memory card 
with Target system -> Load -> To target device. 
 
Note 
Storage location of the IP address 
The IP address and device name for the Control Unit are stored on the memory card 
(non
-volatile).
