If you want to learn DCS on your own, please give me some advice

First of all, DCS does not have a certificate, and secondly, although the overall architecture of DCS systems from different manufacturers has similarities, there are still great differences internally. For example, although the mobile phones produced by different manufacturers are all mobile phones, there are still considerable differences in internal maintenance.

If you want to learn deeper, learn "Analog Electronics" and "Digital Electronics", and then learn "Microcomputer Principles" from a single board computer, and then industrial computer networks, which is basically enough.

Hope it helps.

You need to know about electrical electronics and module programming. You can study on your own, and you don't need to go to school. There is no curriculum for learning. I have hardware information. Hope that helps.

DCS Operator: Use a computer.

DCS Application Engineer: Basic loop inspection, understand the loop signal transmission relationship, understand the software application DCS engineer: DCS development engineer such as field wiring, control system network structure, software and hardware working principle, etc

Electronic circuits, communication technology, automation principles and other DCS is the English abbreviation of distributed control system (distributed control system), also known as distributed control system in the domestic automatic control industry. It is a new type of computer control system relative to the centralized control system, which is developed and evolved on the basis of the centralized control system.

It is necessary to learn the basic knowledge of single-chip microcomputer, the basic knowledge of PID, the principle of electrical appliances, the process flow, and the digital-to-analog conversion. Also learn how to use the DCS system software you use.

I am not majoring in automation, and now I am also engaged in DCS work, introducing this book Chemical Instrumentation and Automation (Chemical Engineering and Technology Major) (Fourth Edition) Dangdang.com You can buy this textbook is very elementary and comprehensive.

At least 4 to 20 milliamps linear output to understand what it means. If you have the opportunity, it is best to participate in the training of DCS manufacturers, if not, you can find textbooks to learn by yourself. Learn system hardware, system configuration, these are primary, and after learning programming.

As long as you study by heart, it will be no problem. Our factory uses central control, if you need it, I can send you some materials.

The DCS system software is developed by a specialized company, and the manufacturer is generally responsible for personnel training during engineering applications.

Knowledge required for DCS system software applications:

1. You need to know some knowledge of logic gates, such as: AND gates, OR gates, NAND gates, OR gates, RS triggers, etc., which are used to help you understand the logical relationship between switches and configure them logically through DCS software;

2. You also need to understand the properties and meanings of PID, automatic manual station (MA), T switching, double T switching, functions (FX0, filter (lead lag), high and low limits, addition, subtraction, multiplication and division, high selection, low selection, etc., which are used for logical calculation and configuration of analog quantities;

The people who are engaged in DCS work say that the subjects that are used more in the work are: circuit principle, computer theory and application, power electronics technology, automatic control theory, process testing and instrumentation, process control, motion control, computer control system, introduction to systems engineering, introduction to automation, embedded system principle and design, sensor technology, network and communication technology.

It is recommended that you learn PLC (programmable controller), process control theory (various typical controls such as cascade, three-impulse, ratio control, etc.), computer control theory (which has an introduction to DCS), C language (for scripting in the future). All of the above will be used in future work, and it is recommended that you learn it well.

In addition, according to the industrial advantages of your school, learn some process principles (chemical engineering, metallurgy, power plants, etc.), because if you don't understand the process, you can't do self-control, even if you don't learn it in school, you must learn it to participate in work in the future. Then there is the typical control of the process. That's all.

I majored in automation, graduated three years ago, because I graduated from 2 schools, so I initially worked in a small company, and now I am doing nuclear power control in China National Nuclear Corporation.

1. The system structure of DCS.

2. Instructions for the use of software and hardware.

3. Configuration, programming instructions (as well as some commonly used modules, functions, etc.) 4. Books on DCS daily maintenance requirements.

Many, many, almost 5 copies.

I want to learn DCS but don't know where to start, I hope you can help!

Hello, dear, it's a pleasure to serve you. DCS includes process, operational, and management levels. The process level is mainly composed of a process control station, an IO unit and a dust field instrument, which is the main implementation part of the control function of this forest system.

The operation level includes the operator station and the engineer station to complete the operation and configuration of the system. The management level mainly refers to the factory management information system (MIS system), as a higher-level application of DCS, there are few systems applied to this layer in the domestic paper industry.

I recommend that you start at the process level first.

DCS system learning.

First, figure out the network structure of the system.

Secondly, the role of each network and the key hardware.

Finally, the application of learning DCS is refined.

For example, Honeywell TPS: The network is divided into TPN, LCN, and UCN

TPN: Factory-level network, responsible for the collection of plant-wide information, connected to the LCN through the OPC service station.

LCN: Management management network, responsible for the data exchange between the host computer and the control station, the host computer displays the screen, and is connected to the controller through the NIM node.

UCN: Field layer network, which is responsible for collecting field signals, handing them over to a controller for HPMM processing (CPU) after simple processing.

When it comes to model selection, you need to understand the basic network structure and the role of each component, the controller processing capacity, and the type of IO card.

The most concentrated and complex are the types of IO cards and communication cards, because to collect a variety of different signals, it is necessary to have a certain understanding of field signals and various industrial communication networks to fully understand these.

1. First of all, start from hardware identification, and know what hardware, types, functions, and models are included in DCS.

2. Various control IO card types, functions, models, and wiring methods.

3. Learn wiring again.
