What the discontinuation of the S7-300 means in practice
From 1 October 2025, the discontinuation phase will affect a wide range of components: a total of 268 assemblies from the SIMATIC S7-300 and ET 200M series are concerned. This includes not only CPUs, but also input/output modules, communication processors, function modules, as well as accessories and memory.
At the same time, economic pressure is increasing. In the context of the product status notification P.M410, SIEMENS points out that spare part prices typically rise significantly, as storage, production and logistics for discontinued products become more complex and costly. In short: those who only reorder when a fault occurs are ordering at the worst time possible.
