I guess it is compatible.. I say that with high confidence. Just keep in mind there is a reason why the version changed from "20" then "21" and lastly "22". Maybe the manufacture was made cheaper or it might be another reason. You'll have to dig deeper to know. Attached are S7-200 part numbers as listed in the System Manuals of years 2000, 2005 and 2008. You'll be able to use this to track development of the part numbers and what worked with what by default. Please realise the S7-200 has been replaced by the S7-1200 for several years now.
