● If only the manufacturer can perform changes to a module, only the product version is
shown on the housing of the module (indicated by a cross; in the following example: product
version 10).
Example:
PS 407 10A
407-0KA01-0AA0
X 11
12 13
Recommendation for performing firmware updates
Perform these firmware updates at regular intervals when an opportunity presents itself (such
as during a scheduled plant shutdown).
Supply sources for the latest firmware version
You can request the update files for the latest firmware versions from your Siemens contact
partner, or download these from the Internet (
http://support.automation.siemens.com
cannot access the Internet address, contact Technical Support.
Note
The update file may be supplied in an executable, self-extracting file (.exe). When you want
to perform consecutive updates for different module types of module versions, you must unzip
the update files in separate folders for the different CPUs as follows:
● Type of module
● Product version
● Firmware version
