Can I put a cpu 102 unit instead of cpu 100 for sematic
..
Is there is a special setting for this exchange . Or it works directly
Please advise
 

Hello Tato300,

this change should work without any other settings.

The 102 have double internal RAM  (2048 statements).
The CPU 102 is only faster and acn handle more analog outputs than CPU 100.
The power loss is a little bit higher (100 = 10,7 W.; 102 = 11,4 W).

Also have the 102 a few integrated function blocks (SFB).

For furter informations here the link to the manual S5-100
The technical data of the CPU you can find at chapter 14.3, page 357.

Hope this is helpful.

regards
