For the SIMATIC S7-300 system and the ET 200M I/O system, the  PM400 milestone (product phase-out announcement) is set for October 1, 2023.  The S7-1500 system and the SIMATIC ET 200MP (Factory Automation) I/O system as well as the SIMATIC S7-400 and the SIMATIC ET 200SP HA I/O (Process Automation) systems are available as functional replacements. The discontinuation (PM410) is effective as of October 1, 2025.

Explanation of milestones during the phase-out phase

Announcement of product phase-out (PM400)

Components up to PM400 are available as new parts without restrictions.

However, once PM400 is reached, the components are removed from active marketing, 

that means they are no longer listed in the catalog. 

The product discontinuation (see PM490) is not planned before expiration of a 10-year period following PM400 

. Due to the high dynamics of the component market, however, we cannot 

guarantee that this can be ensured for all assemblies, despite careful planning. 

Type discontinuation (PM410)

Until the PM410 milestone is reached, the components are still available as new parts. Afterwards, they will only 

be available as spare parts or can be returned for repair. We reserve the right to deliver individual components 

only in exchange for the defective part.

Discontinuation (PM490)

Components from PM490 can no longer be ordered. From milestone PM490 onwards, 

only warranty cases will be handled. Replacement and repair will only be carried out 

within the scope of liability for defects.

Below you will find overview tables with the planned dates for the discontinuation of the individual components 

of the S7-300 / ET 200M and references to corresponding successor products.
