[SOLVED] processors type used inside Siemens PLCs

Issak Sdu · Nov 7, 2014

hello

Does anyone knows what kind of microprocessors or microcontrollers are used inside Siemens PLCs such as S7 200 or 300 ?

I appreciate if someone provides me with a photo of internal pcb.

Thanks

Check out this data sheet for Siemens S7 200.Although this does not have the photo of the internal PCB,it has all the programming procedures included.

actually i just need to know what microprocessor/microcontroller Siemens uses inside their PLCs

At least S7-300 is using the Siemens/Infineon C165 core. Older CPUs have series processors, newer dedicated ASICs, see e.g. below photo from CPU313C.

And a classical CPU314IFM with C165 series processor
