10.5.3 Drive control with PROFINET
PROFINET interfaces
The CBE20 option module can be inserted in the option slot of a CUD. The CBE20 is a
PROFINET switch with four ports.
Note
Ring topology
When connecting the ports, it must be ensured that for standard applications a ring topology
is not created. Additional information on ring topologies can be found in Chapter Media
redundancy (Page 475).

This function checks the correct assignment to a module and its interfaces.
1. In HW Config or the STEP 7 Manager, select the menu item "Target system" > Ethernet >
Edit Ethernet node".
The "Edit Ethernet Node" dialog box opens.
2. Click the "Browse" button.
The "Browse Network" dialog box opens and displays the connected nodes.
3. Select the CUD with inserted CBE20 as node.
The "DCP flashing" function is then activated via the "Flash" button.
The "DCP flashing" function is activated on the RDY LED (READY LED 2 Hz, green/orange
or red/orange) on the CUD.
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 STEP 7 V5.3 SP1 via Ethernet.
