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

  • Entry
  • Associated product(s)
The S7-1200 tool enables you to specify the IP address of one or several S7-1200 CPUs without using the STEP 7 (TIA Portal) software.

Description
You have to fulfill the following requirements for your PG/PC if you want to use the S7-1200 tool:

  • Operating system: Windows XP, Windows Vista and Windows 7 (32-bit). The 64-bit version is not supported.
  • Only the TCP/IP communication is supported.
  • For the CPUs S7-1200 firmware up to V3.0.2

Note
This entry will no longer be updated because the described functions and others (like support of the current S7-1200 firmware) are available in the SIMATIC Automation Tool:
SIMATIC Automation Tool - the commissioning and service operation tool for SIMATIC modules

The S7-1200 tool is particularly useful for mass filling; if, for example, you download a project by means of a memory card to multiple CPUs in a network and then have to change the IP address for each CPU.
 

1. Set the PG/PC Interface

  1.  Click the "PG/PC Interface" button.

  2. Select the following access point for the application: "S7IPTool".
  3. For "Interface Parameter Assignment Used:" you select "TCP/IP" and the network card you are using. You achieve the best results with the "TCP/IP(Auto)" for automatic configuration of the network card you are using.
  4. Accept the settings with "OK".

  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.
     

    Fig. 12
     
  5. Your changes are shown in the Network Mapping table. Click the "Update" button to apply the new network settings of all the CPUs.

Information on the icons

  • A green circle next to the S7-1200 CPU indicates that the update has been successful.
  • A red circle indicates that the update has failed.
  • A yellow circle indicates that the S7-1200 CPU is in the process of being updated.

4. Additional Functions

  1. Click the "Fault Capture" button to read out system information from the selected S7-1200 CPU. This information can be forwarded to Siemens for analysis.
