Are there any sites, which focus only on MES and MIS and Level 2 applications in automation?

With information about the product offerings, forums, etc.

 

Could you define "Level 2"? I've found different definitions that vary from a 3 to 5 "level" model. What are you trying to accomplish? Inductive Automation has information under "Enterprise Integration 101". I'd be happy to answer specific questions.
