Hello,

Have a look at the following topic:

Release S7-1200 CPU Firmware version V4.5

----------------------------------------------------------------------------------------------------

1-The new firmware version can be loaded on any S7-1200 hardware with a firmware version V4.0 or later.

2-To configure the SIMATIC S7-1200 CPUs version 4.5 and higher it requires the Engineering System Step7 with version V17.0 and higher, Basic or Professional. SIMATIC Step7 Safety Basic or Advanced V17 is required for Failsafe CPU types.

3-An S7-1200 CPU with version 4.5 is replacement compatible with an S7-1200 and firmware version 4.0, 4.1, 4.2, 4.3  and  4.4. This enables the use of a real existing CPU with firmware version 4.5 with an engineered V4.0, V4.1, V4.2, V4.3 or V4.4 based on an existing TIA portal older versions project. The new firmware features cannot be used in that case.

• It is not possible to add S7-1200 firmware V4.5 to Step7 V16. 
  
  
• The hardware configuration in Step7 can be anything between firmware V4.0 to V4.5, even if the actual firmware is V4.5. The PLC works in compatibility mode, functioning as configured in Step7.
  
  
• Step7 V17 only mentions firmware V4.5. Step7 does not see the difference between V4.5.0 or V4.5.x ( x = 1 .. ∞ ). Use V4.5 in the hardware configuration for your PLC.
