Answer Posted / gyani
PlC has to read all its data itself and to generate o/p
accordingly,if the system is big the scan cycle goes high
and any changes in i/p could scan & dispaly little late.DCS
have many sub processor who update their data and give
summery to DCS,so DCS have to scan only these sub cpu hence
it improves the scan cycle and system becomes faster.Now PLC
has also coming with big data handling capacity with low
scan cycle.
