Title: What is legacy DCS. How it looks?
1What is legacy DCS. How it looks?
2What 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.
3What 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.
4Challenges of legacy DCS?
Sharing information from DCS - missing
5What 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.
6What 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.
7What is the way to ease challenges?
Indus
way!
8What are the key benefits?

Structured informationProposed
9What is the way to ease challenges? Structure it.
10What 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.
11What are the key benefits?
Proposed solution
12What 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.
13What 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.
14What 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
15What will make it work?
- Dedicated p4 and above PC.
- Connectivity to DCS through RS232 port.
