How do you change the IP address of an S7-1200 without using STEP 7 (TIA Portal)?

2. Manual assignment of an IP address for your S7-1200

1. Double-click the "Update accessible devices" button to update the list of accessible nodes.

3. Select the CPU to be configured from the list of accessible devices.
4. Click the "Flash LED lights" button to flash the status LEDs of the CPU selected.

7. Then click the "Set" button.
8. If you enable the "Set as Default" option, the current settings are saved as "Default" settings when you click the "Set" button.
9. Click the "Use Defaults" button to load the saved "Default" settings.
10. Click the "Start CPU" button to put the CPU into RUN mode.

3. Network Mapping

1. Mark the network card folder in the tree view. A table is displayed listing all the connected S7-1200 CPUs.

2. Click the "Export..." button to generate a CSV file with the current network settings of all the connected S7-1200 CPUs. Save this file on your computer.
    
   
   Fig. 10
    
3. Open the exported CSV file with Notepad. Each line in the CSV file contains a MAC address, IP address, subnet mask and gateway address for each separate S7-1200 CPU. You can change the network settings of each CPU as required. You must not change the MAC address! You can use the "#" character to insert comments in the CSV file.

4. Click the "Import..." button and select the modified CSV file from Step 3.
