Part 2 (IEC61131-2) deals with hardware only (part 3 with programming languages). Now, if a PLC bears the CE mark, it should, in principle, comply with part 2. Schneider PLC's, among others, do. For part 3, it is actually the programming software (usually runs on a PC) that needs to comply. I hope I put you in the right focus.

There is an association in Europe & USA called OPEN PLC , so check for it using your favorite search engine

IEC 61131-2 deals with hardware only. (All IEC standards now have 6NNNN numbers). To bear the CE mark, PLC hardware must comply with this standard
(an others, generic).
