"It's such a big span?" Jia Luansong asked in surprise, "No matter how you look at it, the concept of ECM is not as exaggerated as the time machine, right?"

"I'm really exaggerating to say this... Just say that, the world's top electrical manufacturers, and the world's top software manufacturers, may not be able to do this so-called ecms."

"It's easier to understand this..." Jia Luan sighed relievedly and said, "What are you anxious? What you said is 'not necessarily done', not 'must not be able to do it', right?"

"The problem is that a bunch of Silicon Valley geniuses are doing it. Should we find a group of people selling pirated plates in Zhongguancun?"

Jia Luansong smiled silently.

Hu Haitao suddenly felt abrupt: "Sorry... I'm a little anxious and angry... Zhang Yifu should have done it honestly. It's really eye-catching, but it's almost like giving up automatically."

Jia Luansong narrowed his eyes and looked at the experts around him: "They looked very seriously and don't think it's ridiculous yet?"

"That's because they don't understand our technical foundation." Hu Haitao still shook his head, "Zhang Yifu is expanding, too imaginary... he just made a breakthrough in the small major of traveling wave computing... he felt that nothing could stop him."

"Director Hu, how long have you known Zhang Yifu?"

"More than a month?"

"I've known each other for a few years." Jia Luansong smiled gently, "He won't bet on things, nor will he bet on so much money, energy and trust when he is so important."

"Oh..." Hu Haitao no longer argued. In his eyes, it was because Jia Luansong did not have a deep understanding of this professional field that he developed such blind confidence. After all, he was young and easily confused by Zhang Yifu's limited achievements and personal charm.

Just as he was about to understand more, he heard Larson next to him exclaim.

"This..." Larson rubbed the naked sky cover in surprise, "This works!"

The audience was in an uproar.

Larson is undoubtedly the best expert, how could he say this?

Larson raised his glasses and said seriously: "We all know that there are three difficulties in implementing ECMs. One is the network environment, the second is the interface connection with DCSs. The third is a strong enough central system. Some attempts have been made in the international community to overcome these three points, but this requires huge transformations on the existing basis, and changes must be made from wiring to structure. The results are unpredictable and profits are difficult to determine, so few people have made real changes."

"I support this statement." Thomas followed closely and said, "As a power plant manager, I understand that this situation is unknown, and the things in front of me are just enough to meet the application. In addition, there are very few new large thermal power plants built in developed countries, so many things about ECM are still in the theoretical research stage and have not really invested in it."

"This makes sense, but it still cannot overturn the three contradictions that Mr. Larson said." A brown-haired expert thought, "First of all, it is the network environment, or communication technology. If you realize ECM, everything will be collected and controlled through the power plant network, and the huge amount of electricity will also be involved in the DCS system. Including the calculation, let alone whether the communication environment can remain unobstructed. It is probably difficult to guarantee the response speed, and it may not be more optimized than DPU."

Bill, a Canadian expert who supports Shenzi (Mitsubishi) conservative route, grabbed a handful of thick brown hair and echoed: "Yes, data needs to be transmitted into DCS, calculated, given the results, and then fed back to electrical equipment. Any point in this process is delayed or blocked. It is a huge trouble. Traditional automation itself is flexible and decentralized. Now it has to be integrated. Once the point is broken, there will be nothing."

"Have you seen the back part yet?" Schroeder coughed, "Please look at page 14. Hengdian has given a clear solution on the communication method. The complete system will use fieldbus technology."

Everyone hurried to this page, some people were thinking, while others were confused.

Fieldbus technology (fcs) sounds so high-end, but in fact there is a straightforward explanation for networking. To make a little deeper, it means that the entire power plant will form a unified and standardized network environment, mostly Ethernet.

More directly, Internet cafe wiring can also be called fieldbus technology, but it is much simpler than industrial buses.

The reason why it sounds so high now is simply because the application of Ethernet is limited and the relevant standards are not mature enough. It is worth mentioning that in industrial automation, including power generation, its mainstream communication method is still analog signals. Usually one-to-one and single-loop, with poor anti-interference ability, and accuracy and stability will also be affected by the signal. Compared with systems based on fieldbus technology, this gap can be understood as the gap between directly plugging in a TV cable and watching digital TV through a set-top box. The clarity, information volume, and interactivity of the two are incomparable.

However, due to the popularity of Ethernet and the chaotic standard situation, fieldbus technology is limited. In the current power plant automation pattern, most of them still use analog signals. Occasionally, there are some relatively small areas and experimentally used digital signals, and the practical effect is average. This analog and digital mixing method actually creates an unstable situation. Some people will compare this situation with a simple analog signal situation and blame the fieldbus, which is not as stable as the traditional method.

This time, Hengdian proposed a complete fieldbus technology. With the exception of backup, the key areas that require hard wiring are all based on industrial Ethernet bus technology. Almost ten years earlier, it proposed the entire factory-wide digitalization.

Bill chuckled and put down the material: "You can't say anything, we just think he can do anything, right? I also said I will be elected president tomorrow?"

Another echoed: "It may not be harder than a full fieldbus."

"Haha." The few people laughed.

"Wait, gentlemen, please read the instructions carefully." Schroeder still looked like an old scholar. "Hangdang will adopt the Profibus fieldbus standard. The stability and practicality of Profibus have been certified by our IIC and are an international general standard. I don't think this standard cannot meet the needs of Beimo."
