The 31st Summer Universiade of the World University solemnly opened on the evening of July 28th in Chengdu,

Sichuan Province

In the center of the venue, the Chinese cultural heritage symbol "Sun Divine Bird" rotates flexibly, with twelve

golden rays shining. Fireworks burst into the air with countdown numbers, and the entire audience shouted in

unison with the numbers. Amidst cheers, splendid fireworks bloomed in the night sky. The opening ceremony

of the Chengdu Universiade has officially begun.

In the center of the venue, the sacred flame tray with the pattern of "Sun God Bird" slowly rises. 31 torchbearers,

including astronaut Ye Guangfu, held the torch high and entered the site. Under the attention of the crowd, the

torchbearer ran to the sacred flame tray, formed a circle, and lit the "Sun God Bird" with the torch in his hand,

instantly shining brightly. The flame of the Universiade is blazing brightly, conveying the beautiful wishes of college

students from all over the world, shining like sunshine.

Illuminate the world, hear the singing of life, "" Illuminate the future, look into the beautiful distance "... Young

college students gathered under the holy flame and sang the opening ceremony theme song" Achieving Dreams "

together, turning the entire stadium into a joyful ocean.

The main design of the emblem of the Chengdu Universiade is based on the first letter "U" in the corresponding

English University of the World University Games. The overall color of the "U" is divided into four gradual color

blocks: bright red, bright yellow, emerald green, and lake blue, and it comes down in one continuous line with the

logo elements of the International Federation of General Education.

Similar to the emblem, the mascot of the Universiade, which has attracted much attention from the outside world,

can also be seen as "Chengdu style" at a glance. The mascot of the Universiade, "Rongbao", is based on the real

giant panda "Zhima" of the Chengdu Research Base of Giant Panda Breeding. The facial concept of "Rongbao"

refers to the facial makeup style of Sichuan Opera, a treasure of traditional art, which is an innovative embodi-

ment of the combination of Sichuan Opera, China's Intangible cultural heritage, and the local characteristics of

the Universiade.

The Chengdu Universiade will be held from July 28th to August 8th. This is the second Summer Universiade

held in Chinese Mainland after 2001 and 2011.

During 28 July to 8 August, we will have a promotion of our products to celebrate this event.

Difference of DCS, PLC and FCS in system

1. Main points of difference

(1) How much I/O information the system can handle.

(2) How much control-related control loop information the system can handle.

(3) How many users and devices (CRT, control station, etc.) can be adapted.

(4) How thoroughly the integrity of the transmitted data is checked.

(5) What is the maximum allowable length of the data highway.

(6) How many branches can be supported by the data highway.

(7) Whether the data highway can support hardware produced by other manufacturers

(programmable logic controllers, computers, data recording devices, etc.).

At present, in the DCS system--Siemens 6ES7314-6CH04-0AB0 CPU 314C-2 DP Compact CPU, two types of

 communication methods are generally used, namely synchronous and asynchronous. --Allen Bradley

The end of May and the beginning of June belong to the summer season, which is the second season of the year and

one of the four seasons. The northern hemisphere is most notable for its high summerntemperatures, which can produce

hot and dry or hot and humid and rainy climates depending on the region and the dry and wet conditions.

With spring growing, summer growing, autumn harvesting and winter storing, summer is the best season for many crops

to flourish, with plenty of light and suitable temperatures and abundant rainfall giving plants the conditions they need.

The monsoon climate is a key feature of our climate, with the summer being influenced by warm and humid air currents

from the ocean, making it hot, humid and rainy, with rain and heat at the same time, which is conducive to crop growth.

Crops enter a vigorous growth phase in summer

Time always flies and before we know it we are saying goodbye to May! What comes around comes around, what goes

around goes around, continue to be brave and follow your dreams, stay humble, let the past go by and let the future

happen. May all dreams be lived up to. In June, try to be yourself. Every best day is today, and every day full of expectation

is tomorrow. Try to meet the sunset with hope, everything is just right. May all your wishes come true.

Goodbye, May; rise up, June!

Happy Chinese Lunar New Year 2023

Lunar New Year 2023 is the Year of the Rabbit and begins the following day, 22 January 2023. More specifically, it lasts until 9 February 2024.

The date is determined by the Chinese lunar calendar, which is based on the cycles of the moon and the sun and is usually 21-51 days later than the Gregorian calendar (which is used internationally).

Lunar New Year, also known as Chinese New Year, is celebrated over multiple days and marks the beginning of the next 12 months on the traditional lunar and solar calendars.

It is celebrated by many people of Chinese descent and is also observed in other Asian countries, including Korea, Japan, Indonesia, Malaysia, the Philippines and Singapore.

International Labor Day, also known as May Day or May Day, is a national holiday in over 80 countries around the world. It is

scheduled on May 1st every year. It is a holiday shared by working people all over the world.

In July 1889, the Second International, led by Engels, held a congress in Paris. The meeting passed a resolution stipulating

that international workers would hold a parade on May 1, 1890, and decided to designate May 1 as International Labor Day.

The State Council of the Central People's Government made a decision in December 1949 to designate May 1st as Labor

Day. After 1989, the State Council basically commended Model worker and exemplary individual every five years, with about

3000 people each time.

The significance of International Labor Day lies in the fact that workers have achieved their legitimate rights and interests

through struggle, with a tenacious and heroic spirit of struggle. This is a historic progress in human civilization and demo

-cracy, which is the essence of May Day. That's why people pay so much attention to Labor Day.

Labor is not only related to human health and wisdom, but also to human happiness and beauty. Labor makes our lives rich

and colorful, and labor exercises and cultivates us as humans. The greatness of a person lies in the ability, ability, and love

of labor. A life without labor is meaningless, and a life that reflects labor is full of happiness

Dear friends, Christmas is here! The combination of this Western festival and Chinese tradition makes this festival more colorful and warm! Let's see how Chinese people celebrate Christmas together

1. Stick traditional window decorations and hang red lanterns at home. Integrating these traditional Chinese elements into Christmas decorations not only adds a festive atmosphere to the home, but also adds a strong Chinese flavor to the holiday.

2. Christmas cuisine is essential! In addition to traditional Christmas turkeys, pudding, and cakes, we can also add some traditional Chinese cuisine. For example, roast duck, dumplings,rice dumpling, etc. These delicacies make the Christmas feast more delicious.

3. To make festivals more interesting, it's worth trying to combine Hanfu with Christmas costumes! Alternatively, choose a gorgeous Hanfu or pair it with Hanfu elements under a X`mas hat. This style blends tradition and modernity, giving it a unique flavor

4. On this special holiday, giving gifts with Chinese characteristics will leave a deep impression on people. You can choose Chinese calligraphy and painting, tea sets, Chinese knots, etc., all of which are unique gifts with Chinese cultural characteristics, conveying our blessings and care.

During festivals, we often miss our loved ones with a grateful heart, thanking those who have helped us achieve success or will help us achieve it. It is in this spirit that we express our gratitude to you and wish you all the best for Christmas and the New Year.

Festival is a traditional festival of the Chinese nation, the folklore around the more or less the same, but to discuss its

origin, like a magnetic needle guide, "all brush" pointed to more than 2000 years ago was issued The festival is a great

opportunity for people to learn more about the poet Qu Yuan.

People's admiration for Qu Yuan crossed geographical boundaries early on. Qu Yuan lived in a time of strife between

vassals and lords, he was a great official of the state of Chu, while the Han dynasty rhetorician Jia Yi, who mourned him,

was born in Luoyang, a place where the Chu people had the intention of claiming power. The great historian Sima Qian

wrote a biography of him in The Records of the Grand Historian.

Nor has people's admiration for Qu Yuan been eroded by time. The Dragon Boat culture actually has several origins, like

the legend of the Dragon Boat on the land of Wu Yue, which is distinct from the ancient Chu culture. However, over the

millennia, the story of Qu Yuan has become a household name, and the chapters of the Ch'u rhymes have become even

more popular. The wind and clouds have scattered, time and space have changed, and the cultural peak has become

more and more lofty.

The Dragon Boat Festival, with its rich cultural heritage, is also taking on a more youthful glow, becoming an important

point for the nation to feel the cultural heritage and nurture family sentiments.

Excellent Chinese traditional culture is the wisdom of Chinese civilisation and the essence of the Chinese nation's roots and

soul, is our foundation in the world's cultural turmoil to stand firm. Some people interpret "Duanwu" in this way: "Duan"

means "end", "Wu" means "righteousness". The Chinese road based on the deep Chinese cultural heritage is a road of self-

confidence, self- sufficiency and self-improvement.

It`s bank holiday in China, so we`d better accomplish orders before holiday in order not to make your shipment delay.

Any questions, conatct with us, thanks. This is Vivi`s E-mail:  (sh_plc@163.com).  

(1) The DCS system is a large system. Its controller has powerful functions and plays an important role in the system.

The data highway is the key to the system. Therefore, the overall investment must be made in one step, and sub-

sequent expansion is difficult. However, the functions of FCS are completely decentralized, information processing is

on-site, and digital intelligent field devices are widely used, which makes the functions and importance of the controller

relatively weak. Therefore, the investment starting point of the FCS system is low, and it can be used, expanded, and

put into operation at the same time.

(2) The DCS system is a closed system, and the products of various companies are basically incompatible. The FCS system

is an open system, and users can choose various devices from different manufacturers and brands to connect to the field-

bus to achieve the best system integration.

Power supply to power the programmable controller

In the power system, using 220V DC power supply (battery) to power the programmable controller can

 significantly reduce the interference from the AC power supply, and can also ensure the normal operation 

of the programmable controller when the AC power supply disappears. In the power input terminal of 

some programmable controllers (such as FX series programmable controllers), there is a diode rectifier 

bridge that directly rectifies the 220V AC power supply, and the AC voltage is rectified and sent to the 

switch in the programmable controller power supply. 

The input voltage range of the switching power supply is very wide, and this programmable controller can 

also use 220V DC power supply. When using an AC power supply, each diode of the rectifier bridge only 

bears half of the load current. When using a DC power supply, two diodes bear the full load current. ( Allen Bradley 1747-P4 SLC 500 Power Supply, B&R X20PS2100 Power Supply Module, Siemens 6ES7400-2JA10-0AA0 SIMATIC S7-400  B&R X20BM11 Bus Module)

Considering that the power input current of the programmable controller is very small, when designing 

The rectifier diodes generally have a large margin, and there will be no problem if the DC 220V power supply voltage is used. After long-term industrial operation, it is proved that the above scheme is feasible.

Power supply`s running in PLC module

The low-pass filter can absorb most of the " burrs " of the power supply .L1 and L2 in the figure are used to suppress

high-frequency differential mode voltage . L1 and L2 are reversely wound on the same magnetic ring with equal

length wires , The magnetic flux generated by the power frequency current in the magnetic ring cancels each other,

and the magnetic ring will not be saturated. 

The magnetic flux generated by the common-mode interference current in the two lines is superimposed in this ring,

and the common-mode interference is blocked by L3 and L4. C1 and C2 in the figure are used to filter out the

common-mode interference voltage, and C3 is used to filter out Differential mode interference voltage. R is a varistor,

its breakdown voltage is slightly higher than the highest voltage of the power supply, and it is usually quite open. It is

broken down when it encounters a peak interference pulse, and the interference voltage is clamped by the varistor.

 At this time, the terminal voltage of the varistor is equal to its breakdown voltage.
