Labview is really easy to program but requires more PC power and Lot of time for programming on the other hand .Net is very easy and interfacing with external hardware with the different interfacing protocols . in this project I am going to use Ethernet and USB for communication between PC and the Hardware modules
There are lot of typologies in which you can connect your DCS such as star ,ring , hybrid ect... but one of the most efficient is the BUS topology . Speaking in Computer terms imagine your DCS module as Client Computer in which input devices are transmitters and sensors, the output devices are Led indicators and control valves ect.. you can access the remote computer's input and output data from an another computer (Control Terminal) via. network switch (router) not just one terminal can be accessed by many terminals.
The above Topology Is called as Redundant BUS Topology between both the bus ( A& B) there is a small micro-controller which switches between BUS A&B in case of any errors.
That's All for the basics the next post is about the Project details
