DCP flashing 
This function is used to check the correct assignment to a module and its interfaces. This 
function is supported by SINAMICS S110 with CU305 PN. 
1. In HW Config or STEP7 Manager, select the menu item "Target system" > "Ethernet" > 
"Edit Ethernet node". 
2. The "Edit Ethernet node" dialog box opens. 
3. Click on the "Browse" button. 
4. The "Browse Network" dialog box opens and displays the connected nodes. 
5. After the SINAMICS S110 with CU305 PN has been selected as a node, activate the 
"DCP flashing" function by means of the "Flash" button. 
The "DCP flashing" function is activated on the RDY (READY LED 2 Hz, green/orange or 
red/orange) LED display on the CU305PN. 
The LED will continue to flash as long as the dialog is open. When the dialog is closed, the 
LED will go out automatically. The function is available as of STEP7 V5.3 SP1 via Ethernet. 
STEP 7 Routing 
The CU305 does not support STEP 7 routing between PROFIBUS and PROFINET IO.
