Some Notes About update firmware plc (Upgrade or Downgrade) S7-1200
- 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.
- Step 7 (TIA Portal) with version V14.0 and higher, Basic or Professional is needed if you want to configure an S7-1200 CPU V4.2.
