3.8 Install new firmware in CPUs and modules
Firmware updates
TIA Portal
A SIMATIC memory card can install firmware updates in CPUs and modules. Alternative
firmware update methods include using the module information page of a CPU's built-in Web
server, or using the TIA portal online and diagnostic functions.
SIMATIC Automation Tool
The SIMATIC Automation Tool can perform firmware updates on a group of CPUs and
modules. You can use the new format single .upd file and the older (classic) format which
uses three or more separate .upd files.
By default, the firmware update operation does not replace firmware with the same firmware
version and allows only a single processing thread that must complete execution, before the
next device operation is executed. To change this behavior, see the Tool menu (Page 62)
topic. Be aware of the risk of doing multi-thread firmware updates that is described in that
topic.
Note
S7-1200 CM communication modules must be configured before a firmware update
You can use the SIMATIC Automation Tool to update the firmware in unconfigured and
configured SM and CM modules, except for left-side S7-1200 CM devices. For the S7-1200
CM, you must complete a TIA portal CM configuration and download the configuration,
before you can update the CM firmware.
Note
CPU firmware downgrade
You can use the SIMATIC Automation Tool to downgrade CPU firmware (load a previous
firmware version), but the IP address and program may be erased. In this case, the IP
address is reset to 0.0.0.0 and a new network scan is required to communicate with this
device. You must set the IP address to restore your previous network address.
