Applications of Wiring Diagrams
For wiring in the DCS panels at vendor’s place
For continuity checks of wire connections in DCS panels
For IO testing at the time of FAT
For Commissioning of panels
For maintenance after commissioning of panels
Introduction
Initial Situation
Methods used currently to create wiring diagrams: •Developed by Siemens AG
for Hardware engineering of DCS panels
Tec4fde
•Diagramming and vector graphics application developed by Microsoft
MS Visio

Case Study
CLP CCPP Stage2 (PAGUTHAN)
• DCS commissioned in 2012• 650 IOs • Tec4fde used to create
wiring diagrams• It took 2 months to create
the c2loading table and the wiring diagrams.
TATA CCPP Stage1 (TROMBAY)
• DCS commissioned in 2012• 714 IOs • MS Visio used to create
wiring diagrams• It took 2 and half month to
create the c2 loading table and the wiring diagrams.

Challenges In Current Approach
Tec4fde
• Complex procedure• Trained engineers
required to use this tool• Additional server
required to run this tool, thus cannot be used outside office
Visio
• Every diagram needs to be drawn individually
• Consumes lot of time and cost
• Prone to engineering errors
• Cost of MS Visio license
Basic Idea

Goals and Objectives
05/02/2023 9Energy Sector
To save time and human effort
To develop a user friendly and efficient tool
To minimize engineering errors
To produce numerous hardware engineering documents
• Scope to edit diagrams, add text and graphics• Data checks in input database• Produce other hardware engineering documents(eg.
Loop chart, Power supply diagram, earthing concept etc)

Why our approach is a better one?
Advantages overTec4fde
Saves time and cost
Less training hours
Simplified and user friendly
Can be used in any computer
Advantages overMS Visio
Saves time and cost
No supporting software needs to be installed
Avoids manual errors
Error handling and Input data checks
05/02/2023 19Energy Sector
Since SIEWIRE produces wiring drawings in very low time and cost, it becomes possible to produce wiring diagrams in all, big and small projects.
05/02/2023 Energy Sector 20
Additional Advantages
• Tec4fde is beyond
the budget of the project
• No wiring diagram
document used
• Using tabular data instead of graphical wiring
details for panel wiring, FAT panel checks and commissioning becomes difficult.
• Tec4fde used to
produce drawings
In Big Projects In Small Projects
Feedbacks from: • Siemens Employees who have created wiring diagrams before.• Siemens employees working in TATA Trombay stage 2.• Project manager of the TATA project.
