Siemens regularly updates its automation portfolio, discontinuing products as technologies evolve. Alongside these lifecycle changes, price increases on legacy and low-volume products are also affecting how long certain ranges remain commercially viable.
For manufacturers relying on established Siemens systems, this combination of rising costs and product phase-outs can increase the risk of supply disruption.
Using Siemens’ most recent publicly available discontinuation data [1], we can see which Siemens MLFB prefixes are currently most impacted. The graphic below highlights the product ranges with the highest concentration of discontinued items, helping manufacturers quickly identify potential risk areas.
