Siemens PLC and Automation Technical Briefs

If you work with Siemens PLCs, distributed I/O, or automation hardware, datasheets aren’t enough. They tell you limits. They don’t tell you what breaks, what’s confusing, or what everyone gets wrong the first time.

These technical briefs explain how the hardware and software behave in real applications. They cover wiring, configuration, common mistakes, and practical design limits.

Each article includes:

  • Clear explanations
  • Annotated diagrams that highlight the important parts
  • Troubleshooting notes based on real failures
  • Specific DigiKey part numbers used in the examples

The articles are organized by topic, including:

  • Siemens hardware components and protection
  • Distributed I/O systems
  • LOGO! controllers
  • S7-1200 PLC programming in TIA Portal
