Functions, advantages of DCS and How DCS works?

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
