Executive Summary A Digital Factory uses end-to-end lifecycle data and model-based simulation to mirror, evaluate, and optimize production in a virtual environment—then extends that capability across the entire product lifecycle. The aim is not full automation replacing people; it is augmenting people with real-time data, precise guidance, and intelligent analytics to raise throughput, quality, and

1) Why daily inspection is mandatory Daily rounds are not “walk-throughs”—they are a legal and safety requirement to catch issues early and prevent incidents. For hazardous chemical operations and petrochemical plants, typical requirements include: Frequency: At least two rounds per day by electrical/instrument teams; hourly patrols for key equipment and major hazard zones. Communication: Inspectors

(Based on IEC 61508 & IEC 61511) Overview Safety Integrity Level (SIL) certification is a critical process for ensuring functional safety in industrial automation systems, particularly Safety Instrumented Systems (SIS). To achieve compliance and minimize risk, the certification process must adhere to international standards (IEC 61508 for E/E/PE systems and IEC 61511 for process industry

1. General Requirements The installation and use of pressure gauges, safety valves, level gauges, and thermometers shall comply with the Regulations on Safety Technical Supervision of Pressure Vessels. The calibration and maintenance of pressure gauges shall comply with relevant national metrology regulations. Pressure gauges must be calibrated prior to installation, with the maximum working pressure

1. Define Control Objectives Before touching parameters, agree on measurable targets for the loop: setpoint tracking speed, allowable overshoot, steady‑state error, disturbance rejection, and noise sensitivity. Capture hard constraints (actuator limits, safety margins) and the plant’s operating range. 2. Choose Initial Parameters Pick safe starting values based on prior experience or vendor guidelines. If unknown,
