How to select between Redundant &Hot Standby computers (or maybe controllers)?
Is there any online or printed resource which deals with the selection and application of redundant & hot standby systems in process automation?

I hope somebody can help me out.

Regards,

Sumeet

 

Looks like you're looking for some basic principles. The October 1999 issue of Industrial Computing Magazine covered this topic in a feature article entitled "Tolerant to a fault." You can read the article online at:
