Documentation part, not a hardware module
The 6ED1050-1AA00-0EE7 is the Italian-language LOGO! manual covering the 0BA6 firmware generation — it includes description and application guidance, not a programmable controller or expansion module.
What this manual covers and who needs it
Targets the LOGO! 0BA6 base module family — the Italian text walks through wiring, parameterization, and function-block programming for the built-in logic engine. A panel builder or integrator working with Italian-speaking maintenance crews would stock this alongside the 0BA6 hardware to keep the reference documentation language-matched to the site.
