Introduction
Engineers working with Siemens PLCs, distributed I/O, and automation components often need more than datasheets — they need practical guidance rooted in real-world applications. DigiKey’s engineering team has created a collection of in-depth technical briefs written in a conversational, teaching style. Each brief combines structured explanations, annotated diagrams, and troubleshooting insights you can apply directly to your projects.
This hub organizes Siemens-related articles into categories — from hardware components and distributed I/O, to LOGO! microcontrollers and S7-1200 programming in TIA Portal. Each article is authored by practicing engineers and integrates part numbers available directly through DigiKey.
Use this page as your starting point for Siemens knowledge: learn, design, and then source the components you need through DigiKey’s Siemens catalog.
