Basic light circuits using LOGO! 8

Light circuits are one of the basic applications in LOGO!

This application example includes the following light switching facilities:

  • OFF switch/series connection
  • Changeover switch
  • Intermediate switch
  • Pulse relay
  • Stairwell switching/stairwell light switching

The integrated functions of a LOGO! 8 offer many additional possibilities to solve automation tasks quickly and simply.

In LOGO!, ready-made function blocks, like a weekly time switch, a pulse generator, an astrotimer, an annual time switch, a stopwatch, and simple logic gates, for example support you in creating your projects.


  • You can add other tasks to the installation and to the software program, e.g. room lighting, stairwell lighting, safety and monitoring functions, etc.
  • Simple, star-shaped wiring of the components..
  • Use of simple switches (OFF switches) or pushbuttons instead of complex two-way circuits or cross connections.
  • Integration of inputs and outputs of LOGO! in a KNX system

Target group
This application example is aimed at specialist electrical installation staff.
