Meaning of processed status for itr.

Satya (Professional) (92 Points)

05 October 2016  

For the assessment year a return was filed on Aug 5th. Online status of the return shows as Processed. Also a text message was received saying : ITR for PAN: ACHxxxxx5K, AY 2016-17 and Ack No.XXXC6 has been processed at CPC.Order u/s 143(1) will be sent by email. 

What does this status mean ? Is the assessment complete ? Is the return revision not possible any longer ??
