I don't have a good way, so let's look online first.

This is very easy, go to the ** network, and then directly spend money to buy a complete set.

Does the water plant have specific process control requirements? Yours wouldn't include the design of the water plant, would you? You write down your requirements specifically, and I may be able to help you when I'm fine.
-
You can make it clear that no, a water plant control is over. Your requirement column, the quantity column to be detected, what column to monitor on the host computer, and what kind of column is the process. Please be clear.

Accusing me of often impromptu answering the problems encountered by students in graduation and innovation projects on the spot, stealing the limelight, covering everything from design skills, processing industry, algorithms, and patent document writing rules, while the highly educated and high-title characters under him are uneducated, dumbfounded, and under pressure, they implement reverse elimination and force me to be laid off and unemployed in advance. This is to undermine basic education and undermine innovation.
Throwing things upstairs and throwing things on the ground floor (we live on the ground floor), dirty and messy, we wanted to give stickers to the residents upstairs telling them not to litter and write what is good.

Do you want so many things without spending a penny? It's really a big man.
-
( o ) Wow, don't give a penny, such a procedure has to be charged.
-
The principle is basically constant pressure water supply, hehe.
There are some on the Internet, as long as you can understand it, your graduation project programming is very easy
-
This kind of project is a project.
How can knowledge be so worthless.
Respect for knowledge is respect for our future.

Abstract Chapter 1 Introduction.
Chapter 2 Design Scheme.
Chapter 3 How it works.
1) Waterworks process.
2) Filtration mechanism of waterworks.
3) Factors influencing the filtration efficiency of waterworks.
4) The selection of filter material for waterworks.
Chapter 4 Design and Calculation.
1) Calculation of the process size of the filter tank of the waterworks.
2) Calculation of the height of the filter layer of the waterworks.
3) Calculation of backwash head loss of filter in waterworks.
4) Calculation of the size of the filter pipe of the waterworks.
Chapter 5 PLC controls the filter process of water plant.
Wrapping up the acknowledgments. References.

I don't have software from Siemens.
Knit it to you with Mitsubishi.
Let's say the motor is water-feeding.
Once the program is done, you can't get it over.
The idea is to assume that there are four level gauges inside the container.
Low level High level Low low level High high level.
Low and low levels allow the motor to work, and high and high levels stop it.
And the low and low liquid level and high high liquid level output alarm signal to the buzzer.

There is a reference for Siemens PLC.
Please check your message for details.
I can't put it here.

You're talking about the constant pressure water supply of PLC control inverter in the waterworks, and I'm working on this kind of project right now.
-
It is best to use PLC to control the frequency conversion, which can ensure the pressure of the water supply without wasting electricity.
-
It's too general to go into details. Control what?What are the control conditions?
-
The brand of PLC and LCD screen is not the same, Beijing Qingyuan Borui, PLC LCD screen for weighing room, the quality is also very good, and its own requirements for products.
-
The next filter control process by yourself, just write the PLC program, don't look for ready-made, it's very simple. Using the graduation project to learn the previous courses is still very helpful for future work.

PLC control system: Programmable logic controller (PLC) uses a type of programmable memory for its internal storage programs to perform user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and control various types of machinery or production processes through digital or analog input and output.
The role of PLC control system: (1) PLC replaces a large number of intermediate relays, time relays, counters and other devices in the relay control system with software functions, so that the design, installation and wiring workload of the control cabinet are greatly reduced.
2) When the PLC or external input device and actuator fail, the cause of the fault can be quickly identified according to the information provided by the LED or programmer on the PLC, and the cause can be quickly eliminated by replacing the module.
3) It has a strong anti-interference ability, and the average trouble-free time reaches more than tens of thousands of hours, which can be directly used in industrial production sites with strong interference.

To put it simply, it is to replace the old control circuit (mainly composed of relays) and save costs. In addition, the PLC control system can carry out a series of calculations to achieve the functions that cannot be achieved by the old control circuits in the past.

Hello, I can answer your questions. In fact, it is simple to understand, PLC is like the CPU of the computer, but the computer system we generally can't write, even if we can write, the system configuration is too wasteful, and the PLC program will learn, and it is also very simple, we can program it, control the object we want to control, it's OK! So it is used in the field of industrial control, as well as other fields that require intelligent control!

To put it simply, it is a replacement for traditional relay circuits.
1. Host. The host part includes the processor (CPU), system program memory, and user program and data memory. CPU is the core of PLC, which is used to run user programs, monitor the status of input and output interfaces, make logical judgments and carry out data processing, that is, read input variables, complete various operations specified by user instructions, send the results to the output end, and respond to requests from external devices (such as computers, printers, etc.) and make various internal judgments. >>>More
