Required user action:
You can install the CPU firmware update from the Web server, the online diagnostic functions of STEP 7, or by
making an SIMATIC memory card using the Siemens customer support Web site that contains the firmware update.
The S7-1200 System Manual documents these methods.
If you use an SIMATIC memory card to install the CPU firmware update, retentive memory is retained. However, if you
use the Web server or online diagnostic functions of STEP 7 to install the update, retentive memory is lost.
If you close the Web browser while in the process of performing a firmware update from the Web server, you will
be unable to change the operating mode of the CPU to RUN mode. If this situation happens, you must cycle power to
the CPU to be able to change the CPU to RUN mode.
