After three decades, the Siemens S7-300 CPUs and the ET 200M range are coming to an end. A generation of Programmable Logic Controllers or PLCs that provided reliable and flexible automation solutions worldwide. Technological evolution is forcing the market for new and improved alternatives in response to the complex needs of tomorrow’s industry.
They played an invaluable role in many industries, but October 1, 2023 marks the end of a historic era: the end of the S7-300 and ET 200M ranges. Although the components will still be available after this date, they will disappear from active marketing and catalogs.
The countdown also starts for the 10-year availability of spare parts, a deadline that may be accelerated by the scarcity of electronic components.
The phase-out is taking place in 3 stages. Thus, two more stages will follow after October this year:
- From Oct. 1, 2025, the items will only be available as spare parts, for repair or exchange.
- The final end of these items falls on Oct. 1, 2033, after which no more parts will be available.
A look back at the successes …
The SIMATIC S7-300 PLC series was initially supported by PROFIBUS fieldbus technology and later by PROFINET. These systems proved to be extremely flexible, very compact and equipped with an active backplane. Even H systems operated with these versatile solutions.
For decades, they guaranteed reliable and innovative
industrial automation, but continuous technological development requires progress. More modern and advanced solutions ensure a higher responsiveness to the challenging needs of industry.
A new generation emerges
The end of an era marks the beginning of a new chapter, full of
possibilities for optimized automation.
Several suitable alternatives are already on the market: ET 200MP, ET 200SP and even ET 200SP HA. Remarkably, ET 200MP already
celebrated its ten-year anniversary. Thus, it is already an established player in the world of automation.
