Sigma engineering team of dedicated engineers and drafters deeply understand the workings of an integrated control system. Our team includes engineers and drafters that have the knowledge and experience to implement the best integrated control system solution for your facility. We have extensive experience working in hazardous locations with class/division ratings. With Study of P&ID , Control Philosophy and Design Criteria , Sigma engineers evaluate and determine the technology needed to make your project a success.


Regarding of specification of the project, SIGMA delivers variety drawings during detail design. These drawings are prepared by Eplan or Autocad software. The drawing package could include the following documents but not limited to:

  • Electrical Equipment Database 
    This is a standard equipment list for the project. All equipment connected by the electrical contractor is made available in electronic format.
  • Process Instrumentation and Control Loop Diagrams 
    SIGMA develops detailed control loop diagrams for all process-related valves, motors and discrete and analog process values.
  • Control System Architecture Drawings 
    This is a complete communication one-line detailing all relevant information for the connections to the integrated process control systems controllers and HMI stations. If fieldbus technology has been implemented, wiring information is also documented within the system architecture drawings. We can also help by evaluating existing installations. We have experience with Modbus, Profibus, Ethernet, foundation fieldbus.
  • Control Panel Layouts and Fabrication Drawings 
    Panel drawings include back plate layouts, details, communication and/or power one-lines, and bill of materials.
  • Control Panel Wiring Diagrams 
    Diagrams include card wiring details, rack layout, and detailed terminal layouts for control panels.
