Description
In order to obtain a quick overview of current firmware versions, the list below contains the current operating system firmware versions of the CPUs.
The download link is in the right-hand column.

In addition, this table also contains information about possible software packages.

• STEP 7
  Standard programming software for SIMATIC controllers
• S7 Distributed Safety 
  Software for fail-safe applications
• iMap
  Software for component-oriented programming

Generally speaking, you should always use the latest version of the operating system on the CPU.
