DCS function:

• DCS works as a tool to control a loop system where one loop can happen some control process.
• Working as a replacement of separate manual and auto control tools to be a unity to be easier for maintenance and use
• Data and data collection means to be obtained a really desired process.

DCS philosophy in the planning

• integration
• distribution
• reliability
• openness
• user-friendliness
• investment security & expandability

How DCS works?

DCS as an automatic control system works in a way

• Collect data received from the field
• Processing the data into a standard signal
• Processing standard signal data obtained with the applicable control system so that it can be applied to obtain a suitable value for signal correction.
• If there is an error or data deviation, then correction is made from the data obtained in order to reach the intended standard value
• After a correction from the data, a deviation occurs a measurement or data collection is performed from the field

Advantages of DCS:

• Access a large amount of current information from the data highway.
• Monitoring trends of past process conditions.
• Readily install new on-line measurements together with local computers.
• Alternate quickly among standard control strategies and readjust controller parameters in software.
• A sight full engineer can use the flexibility of the framework to implement his latest controller design ideas on the host computer
