Issues with DCS operators

These are merely my immature personal opinions for reference only: Since one is an operator, it is of course necessary to be familiar with the process flow, to study the P&ID diagrams, to learn the operating procedures, as well as the procedures for dealing with emergencies and related interlock systems. One should also go to the site to get to know the locations of the main pipelines and valves, thereby gaining a deeper understanding of the production process. It is important to understand the impact of one’s own tasks on the operations in upstream and downstream processes. This is the most basic. Furthermore, by integrating relevant knowledge from the chemical engineering field, it is possible to identify shortcomings in the operating methods, explore optimal operating conditions, identify potential bottlenecks in this device, and improve the plans for starting up and shutting down the system. Have an understanding or familiarity with the basic knowledge of instrumentation, PID control, and be able to perform basic PID tuning. Understanding the basic principles of the sensors on site, such as the significant lag in temperature sensing elements, helps with operation; learning the basic knowledge of interlocks aids in understanding the relationship between interlocks and the manufacturing process.

Are you referring to the users of the control system or its maintenance staff? Their tasks are different. Users only need to understand the basic processes and know how to operate the system; there is no need for them to have in-depth knowledge. Maintenance staff, on the other hand, must be familiar with the hardware as well as basic software programming. If the system being maintained is complex, they need to learn more or maintain contact with the integrator

Learn in detail about the process flow diagram with measurement points, study the DCS operation manual, and become proficient in its use

DCS operators need to be familiar with the process flow； Familiar with on-site operations outside of DCS control ； Be familiar with the location of each operation control point on the DCS at the site ； Proficient in handling abnormal situations, as well as identifying and operating chain control and alarms ； Master the operations at each control point on the DCS ； Learn some basic knowledge of instrumentation ；

If it’s a process technician, the main requirement is to be familiar with the processes, and basic operational skills are sufficient; whereas for an instrumentation engineer, it’s necessary to be familiar with DCS configuration as well as knowledge related to automation principles and other specialized areas in this field.

1. One must be familiar with the on-site process flow. 2. In the event of an accident, the control room must issue the correct instructions immediately; in cases where the nature of the accident is unclear, it should guide the operators on site on how to handle it properly. 3. PI D control, with PID tuning. 4. If you can do it without relying on the instruments, then you’re ready to go.

The process flow is of primary importance. Just like when driving a car, it’s necessary to quickly take appropriate actions based on road conditions; being able to use the brakes or accelerator skillfully is crucial. Yet it’s also possible to assess the current state of the vehicle by considering the readings on the dashboard and one’s own feelings.

It’s just like trading stocks online: first, you need to know how to trade stocks, and second, you need to be able to use stock trading software. Therefore, you need to be proficient in the process flow, understand DCS operations, and have a basic knowledge of DCS configuration. That should be fine.
