3.6.1
Addressing by selecting the target system
Follow the steps below to assign an IP address the first time:
1. Use the STEP 7 function "Display Accessible Nodes" to display the nodes that can be
reached via Industrial Ethernet.
2. Select the required node in the list that then appears.
3. Then select the "PLC > Ethernet Address" menu command.
Result: The previously selected node is then adopted directly in the "Addressing" dialog.
The MAC address of the node cannot be changed.
4. Enter the required IP parameters and assign these to the CP.
Result:
The CP is now available on Industrial Ethernet using the IP address.
Note
In principle, the description applies equally to STEP
7 V5.5 and STEP 7 Professional.
You will find further, more detailed information on the procedures in the online help in STEP
7. There,
you will also find further information and alternative methods.
3.6.2
Addressing by adopting the configured address parameters
Follow the steps below to configure the IP address for a newly inserted CP:
1. Insert the required CP in the S7 station open in STEP 7.
2. Edit the MAC address and, if required, the IP parameters in the parameter group of the
Ethernet interface.
3. In the "Subnet" box, select the Ethernet subnet with which you want to connect the CP.
4. Save your project.
5. Using the appropriate STEP 7 function, start the network search function for accessible
modules.
With CPs that have multiple interfaces, only the PROFINET interface is displayed.
6. Select the CP with the matching MAC address from the available components.
The configured IP address is displayed.
7. Assign the CP the IP parameters adopted from the networking.
8. Then download the configuration data to the target system.
Result:
After downloading the configuration data, the CP can be accessed on Industrial Ethernet
using the IP address.
