I would like to upgrade the firmware version of the S7-300 CPU312c from V2.0.1 to V2.6. Could you please advise me on how to do this? Thank you!

In the hardware configuration, under the options menu, select Target system > Firmware update

I’m referring to step 7; TIA Portal hasn’t been used there yet, but there should still be hardware configuration involved.

There is generally no need to upgrade Siemens’ firmware, unless it is recommended by the manufacturer; moreover, the 300 model has higher stability (in my opinion, much higher than that of the 400 model)

The key point is to download the firmware from Siemens’ official source
