- An S7-1200 CPU FW V4.5.1 (latest version – until now) is a replacement compatible with an S7 1200 and FW V4.x. This enables the use of a real existing CPU with FW V4.5 with an engineered V4.x based on an existing TIA Portal older versions project. The new FW features cannot be used in that case.
- You can update an S7 1200 CPU Firmware V4.x (Article No. 6ES721x-1xx40-0XB0) to the latest version (until now is V4.5).
- To configure the SIMATIC S7-1200 CPUs V4.5 you need Step 7 (TIA Portal) with version V17.0 and higher, Basic or Professional.
- Step 7 (TIA Portal) with version V16.0 and higher, Basic or Professional is needed if you want to configure an S7-1200 CPU V4.4.
- To configure the SIMATIC S7-1200 CPUs V4.3 you need Step 7 (TIA Portal) with version V15.0 and higher, Basic or Professional.
