Necessary requirements for running the above modules and functionalities

To configure the SIMATIC S7-1200 CPUs version 4.3 and higher it requires the Engineering System Step7 with version V15.1 and higher, Basic or Professional with Hardware Support Package (HSP) HSP_V15_1_0276_001_S71200_CPU_4.3. 72341852

Compatibility and necessary components

SIMATIC Memory Card

A SIMATIC Memory Card can be used optionally for expanding the CPU load memory, loading the application software or for executing a firmware update.  

Compatibility of the hardware and software

Existing SIMATIC S7-1200 CPUs V4 (Article No. 6ES721x-1xx40-0XB0) can be updated to the new CPU firmware 4.3.

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