To find out the model and firmware version of your Siemens S7-1200 PLC, you can use one of the following methods:



  • Look at the label on the front of your PLC. You will see the model number (e.g., 6ES7 215-1HG40-0XB0) and the firmware version (e.g., V4.5.2) printed on it.



  • Use TIA Portal software to connect to your PLC and read the device information. You will see the model number and the firmware version displayed on the screen.



  • Use a web browser to access the web server of your PLC. You will see the model number and the firmware version displayed on the web page.



To check if there is a firmware update available for your Siemens S7-1200 PLC, you can visit the Siemens website and search for your model number. You will see a list of firmware updates that are compatible with your PLC. You can compare the firmware version of your PLC with the latest firmware version available on the website and decide if you need to update or not.


Step 2: Prepare Your PLC for the Firmware Update




Before you update the firmware of your Siemens S7-1200 PLC, you need to prepare your PLC for the firmware update. This involves backing up your PLC program and data, connecting your PLC to a PC with TIA Portal software, and switching your PLC to STOP mode.


To backup your PLC program and data, you can use TIA Portal software to download the project from your PLC to your PC. This will save a copy of your PLC program and data on your PC. You can also use an SD card or a USB flash drive to backup your PLC program and data.

To connect your PLC to a PC with TIA Portal software, you can use a USB or Ethernet cable to establish a physical connection between your PLC and your PC. You can also use a wireless connection if your PLC supports it. You need to make sure that your PC has TIA Portal software version V16 or higher installed on it.


To switch your PLC to STOP mode, you can use TIA Portal software to change the operating mode of your PLC from RUN to STOP. You can also use a switch on the front of your PLC to change the operating mode manually. You need to make sure that your PLC is in STOP mode before you start the firmware update process.


Step 3: Download and Install the Firmware Update




To download and install the firmware update for your Siemens S7-1200 PLC, you need to follow these steps:



  • Go to the Siemens website and search for your model number. You will see a list of firmware updates that are compatible with your PLC.



  • Select the latest firmware update file that matches your hardware version and download it to your PC. The file will have a .zip extension.



  • Extract the .zip file to a folder on your PC. You will see a .bin file that contains the firmware update data.



  • Open TIA Portal software on your PC and connect to your PLC. You will see your PLC device in the project tree.



  • Right-click on your PLC device and select "Update operating system". A dialog box will appear.



  • Browse to the folder where you extracted the .bin file and select it. Click "Open". The dialog box will show you some information about the firmware update file.



  • Click "Start". The firmware update process will begin. A progress bar will show you how much time is left until completion.



  • Wait until the firmware update process is finished. Do not disconnect or power off your PLC or PC during this process.



  • Click "Close". The dialog box will close.



  • Verify that the firmware update installation was successful. You can check the firmware version of your PLC using one of the methods described in Step 1.



Step 4: Restore Your PLC Program and Data




After you update the firmware of your Siemens S7-1200 PLC, you need to restore your PLC program and data from the backup. This will ensure that your PLC can resume its normal operation and functionality.


To restore your PLC program and data from the backup, you can use one of the following methods:



  • Use TIA Portal software to upload the project from your PC to your PLC. This will overwrite the existing PLC program and data with the backup copy.



  • Use an SD card or a USB flash drive to transfer the backup file to your PLC. You need to insert the SD card or the USB flash drive into your PLC and use TIA Portal software or the web server of your PLC to restore the backup file.



To switch your PLC to RUN mode, you can use TIA Portal software to change the operating mode of your PLC from STOP to RUN. You can also use a switch on the front of your PLC to change the operating mode manually. You need to make sure that your PLC is in RUN mode before you test its functionality.


To test your PLC functionality, you can use TIA Portal software to monitor and control your PLC inputs and outputs.
