What is DCS?

• Integrates the PLCs and process controllers of
  a process line.
• Enables you to manage the process as a complete
  system.
• DCS lets you see the big picture.
• Improve the overall efficiency and quality of
  your plant.
• In a process industry, DCS is a for plant
  activity.

3
What is DCS?

• Instantaneous controlling and monitoring of
  plant is dominant function for DCS at the
  control room.
• Up to some extent, DCS is performing reporting
  analysis job for plant.

4
Challenges of legacy DCS?
Sharing information from DCS - missing
5
What challenges does legacy DCS have?

• Proprietary communication Bus. No access to
  data without software and /or hardware from the
  DCS manufacturer.
• Data Output from DCS is printed on paper.
  Analysis of the data becomes cumbersome and
  many a times impossible task.
• Plant information cannot be made available
  on-line to top executives.
• Maintenance of the proprietary
  spares/peripherals.
• Spares from the suppliers are exorbitantly
  costly.

6
What challenges does legacy DCS have?

• Alarms are printed continuously, leading to
  wastage of stationary.
• Graphic page and the trend page print from the
  DCS is costly.
• Configuration of various reports with
  calculations and various layouts is a time
  consuming manual.
• Lack of MIS.
• Delay in decision making process.
• Operational effectiveness room for
  improvement.

What are ePlant objectives?

• Fetch the data from proprietary DCS system and
  store on commercial PC thru RS232 port.
• Make the process data on-line for better
  monitoring of the plant at various levels of
  management.
• Store the required data in database format for
  in- depth analysis of the plant performance.
• Data is analyzed.
• Information is shared thru LAN / Web.
• No extra hardware required.

Proposed solution
12
What are the key benefits?

• One shot view of the plant on any PC on LAN.
• Database of plant parameters can be established
  for any analysis.
• Instant POP-UP for any critical alarm to the
  concern authority.
• Important graphics can be configured for
  various users.
• Multi trends for data comparisons.

13
What are the key benefits?

• Reports of Raw material, utilities, power and
  finished goods, for specific consumption
  analysis
• Efficiency calculations of Heat exchangers,
  reactors, distillation columns etc can be
  configured into Excel sheet from the data
  captured in structured form.

14
What are the subsequent benefits?

• Freedom from proprietary piracy
• Analyzed tag data can shared beyond the DCS
• Complements your efforts on information flow
• Sharing of DCS info on LAN / Web
• Information sharing at minimal cost
• Produce publish trend analysis thru eOffice
  (Indus tool)
• Produce and publish the alerts to the designated
• Graphical analysis of plant information
• Operational effectiveness leapfrog

15
What will make it work?

• Dedicated p4 and above PC.
• Connectivity to DCS through RS232 port.
