What this manual covers
The 6ED1050-1AA00-0KE7: This is the Chinese-language manual for the Siemens LOGO! 0BA6 series, containing descriptions and application guidance. It is not a hardware module or a programmable logic controller — it is the documentation set for the 0BA6 generation of LOGO! logic modules.
The lifecycle stage is listed as current, meaning Siemens still supports this publication as an active document.
