Mitsubishi Q2a vs Q2as

Hi guys, May I know what is the difference between Q2A & Q2AS, I try to find the Q2AS user manual from the web, but no luck, is this CPU obsolete? One of the CPU in our client site having error 220 - parameter missing - system can't run. So i'm trying to google for more info. Thanks guys.

The parameter error indicates the parameters are missing from the CPU. Typical cause would be loss of pLC battery so loss of program memory. QnA was a 10" tall model, while QnAS is a 5" small model. Programming is the same as the current Q Series. You should be able to find manuals on the Q2AS on www.meau.com or other Mitsubishi support sites. QnA is obsolete, as is all 10" A Series product. QnAS and the small rack systems are not obsolete.
