These question is very difficult in todays Automation
system, Because Today's PLC is much more upgraded & working
like a DCS. Although PLC is Better for Sequincial
Operation, Because its Scan Time is less than DCS & DCS
mostly used for Continues Process.
If You see todays PLC, Its IO Capacity is near to DCS IO
handling Capasity. Yaa, one Big Advantage of DCS System is
that Logic of whole process is Split in Defferent different
CM's. So that when change in one CM do not affect other
Proccess.
