PLC Programmable logic controller
DCS distributed Control System
PLC Simplified with limited logic control for like a machine or Simple process with limited interlock logic - progamme can be modified easily.& also proto type.This will give only indication of faiiure.No recording the event or process parameter ,with limited memory.Cost wise it is very cheap
Dcs concern Huge multiple logic controlls with >1000 of inter lock for process of power plant or refineries or any process Industries it will give all types of alarm in soft copy & hard copy about process , failure & record all the process input & out put parameters & efficiency if required .(like Boiler,Turbine, Generator controlls Switch gear cotrolls ie power generation to Transmission It will cover up everything) Very huge memory back up, failuer rate very less.process parameter all are fixed cannot be changed by Individual. Troube shooting very easy .production will not be affected at all .( (stand by system will take care automatically change over)Cost will be very high. I hope I have given you required points Further more points I have to refer more e.mail me

PLC is just one device programmable logic controller which control outputs in depend of inputs by programmed algorithm. DCS is distributed control system and is based on more subsystems which control subpart of whole manufacturing process.
