Re: fieldbus foundation(FCS),DCS,Profibus,which will be domi
DCS is not dead and can never replace with FCS. In modern industrial system the heart of all field devices is FCS, data can be colected via 4~20 mA, Profibus, and Fieldbus, depending on the FIO module which is attach to the FCS. FCS will transfer the data via V-net to DCS system, the DCS will display the output thru Human Machine Interface and some Consoles like Engineering console, User console, Process Management and others, so meaning this 2 system will work together in order to run the plant. Using modern process management monitoring the accessability thru internet, intra-net and other remote web-base monitoring can be done in DCS side.
DCS and SCADA have something in common "To display and collect the data and store in the database". SCADA is event base while DCS is process base monitoring.
Even for the last 5 years of plant history DCS can display the histogram via access of internet, intranet depending on the plant system configuration. DCS was invented by Yokogawa with 30 years of existence. DCS is not limited to medium to large Petro and chem, Medical, Semi-conductor, Manufacturing, Power, Mills, Water, Processing but also to Sea Navigation and Earo-space.
