In today’s digital and automated production environment, Manufacturing Execution Systems (MES) play a crucial role. It can not only help enterprises achieve real-time monitoring and tracking of production processes, but also improve production efficiency and quality. However, to maximize the potential of MES, integration with other production management systems is often required. This article will provide a detailed introduction to how to integrate MES with other production management systems to achieve more efficient production management.

1. Integration of MES and ERP systems
MES and Enterprise Resource Planning (ERP) systems are two key production management systems. MES typically focuses on operational control and data collection at the workshop level, while ERP systems are responsible for planning and managing enterprise resources. Integrating MES with ERP systems can achieve seamless integration between production planning and actual production data, helping enterprises better coordinate production, inventory, and delivery, thereby improving production efficiency and customer satisfaction.
2. Integration of MES and SCADA systems
Monitoring and Data Acquisition Systems (SCADA) are commonly used to monitor factory equipment and production processes. By integrating MES with SCADA systems, enterprises can achieve real-time collection and monitoring of production data, and use this data for MES production scheduling and quality control, thereby achieving more accurate production planning and real-time response to production anomalies.
3. Integration of MES and PLC systems
Programmable Logic Controller (PLC) is a critical system used to control factory equipment and production lines. Integrating MES with PLC systems can achieve automatic issuance of production orders and automatic control of the production process, thereby improving production efficiency and reducing the possibility of human errors.
4. Integration of MES and quality management system
Quality management systems are usually used to track and manage product quality data, including quality inspection results, quality anomaly handling, etc. Integrating MES with quality management systems can achieve real-time collection and analysis of quality data, help enterprises discover and solve quality problems in a timely manner, and improve product quality and production efficiency.
5. Integration of MES and Material Management System
The material management system is responsible for the inbound, outbound, and inventory management of materials. Integrating MES with material management systems can achieve timely supply of materials required for production and real-time tracking of inventory, helping enterprises avoid production interruptions or inventory backlog caused by material shortages or excess.
6. Integration of MES and production equipment maintenance management system
The production equipment maintenance management system is used for equipment maintenance and repair plan management. Integrating MES with production equipment maintenance management system can achieve collaboration between production planning and equipment maintenance planning, helping enterprises to arrange equipment maintenance time reasonably and reduce production downtime caused by equipment failures.

Through the above introduction, we can see that the integration of MES with other production management systems is of great significance for improving production efficiency, optimizing production plans, and ensuring product quality. Therefore, when implementing MES systems, enterprises should fully consider the integration with other production management systems to achieve overall collaboration and optimization of production management.

1. The integration of MES management system and ERP system is the key to achieving optimal allocation of enterprise resources. The ERP system is responsible for the overall planning and coordination of enterprise resources, while the MES management system focuses on the execution and control of production sites.
After the ERP system runs the production plan, it will transmit the production plan information, including production quantity, completion time, process requirements, etc., to the MES system. The MES system allocates corresponding production resources, optimizes production processes, and issues specific production work instructions to lower level workers, equipment, or control systems based on this information.
2. The integration of MES management system and PLM system is an effective means to achieve data management. Through the integration of MES system and PLM system, automatic transmission or means of transmission of product data can be achieved, ensuring that MES system can accurately obtain and use the latest product data in the production process.
3. The integration of MES management system and WMS system is a key step in achieving logistics and production collaboration. By integrating the two, the MES management system can transmit production plan information and finished product completion information to the WMS system, which then allocates materials and updates inventory based on this information. At the same time, the WMS system will also provide real-time inventory information feedback to the MES management system, helping the MES system better execute and adjust production plans.
4. The integration of MES management system and automation layer is an important link in achieving production automation and intelligence. Through the integration of MES management system and automation layer, functions such as automatic issuance of production instructions, real-time collection and analysis of production data can be achieved.

The MES management system can transmit production plans and BOM information to the automation layer, which then executes corresponding production operations based on this information and feeds real-time production data back to the MES system. This can not only improve the automation level of production and reduce the need for manual intervention, but also achieve real-time monitoring and analysis of production data, providing strong support for production decision-making.

The integration of MES management system with other systems is the key to achieving efficient collaboration in production processes. Through close integration with other systems, MES management systems can better play their role, achieving optimized allocation of production resources, accurate management of product data, collaboration between logistics and production, as well as production automation and intelligence. This not only improves the production efficiency and quality of enterprises, but also provides strong support for their development.

Application of CanOpen to Profinet Gateway (NY-N831) Connected Drive Control Integrated Servo in Aerospace Industry: Frontiers and Innovations in Technology.

In today’s highly automated industrial environment, CanOpen and Profinet (NY-N831) communication protocols each play an indispensable role. CanOpen, as a communication protocol designed specifically for embedded networks, has been widely used in industrial automation and robotics due to its high efficiency, stability, and flexibility. It provides fast and reliable data exchange between devices, ensuring collaborative work and efficient operation between devices.

The traditional copper pipe processing methods include:

(1) Copper tube extrusion processing technology

(2) Copper tube upward continuous casting method

(3) Copper tube (seam) welding production technology

(4) Casting and rolling method for producing precision copper tubes

The production of precision copper tubes is a new production process, with two main innovative methods: first, the development of horizontal continuous casting technology for copper tube billets, which is applied to the production of copper tube billets; second, the three roll planetary rolling technology developed in Germany in the 1980s is applied to the reduction of diameter and wall of copper tube billets, replacing extrusion deformation processing and cold rolling processing. The process flow is: horizontal continuous casting tube billets – three roll planetary rolling -, combined drawing – disc drawing – winding – annealing.

(1) The processing route is long, the production cycle is long, and there are circular round-trip processes. There is a strong correlation between processes, which affects both operations and logistics. The heating and hot rolling processes in the furnace need to be linked for processing.

(2) There are many uncertain factors during the processing. The smelting process has strict requirements for ingredients and processes, and minor deviations in the main components or trace elements can lead to incompatible alloy grades. In addition, some processes such as annealing and cleaning in the bell furnace are greatly affected by human factors, and the processing time is uncertain.

(3) The production site environment is complex, and materials are difficult to track. The production and quality information of material rolls is difficult to report to relevant departments in a timely manner, which can easily lead to problems such as leakage and loss.

Based on the production characteristics of the copper rod processing industry, Wanjie Starry Sky Technology divides the MES system into the following main functional modules:

1. Production planning and scheduling management
Production planning and scheduling management are the core modules of the entire MES system. They receive contracts issued by ERP, develop job plans based on equipment and raw material preparation, and combine with the current production status, and issue them to each machine. Generate a raw material demand plan based on the production plan, providing a basis for the material center to organize raw materials. Determine whether a supplementary plan is needed based on the abnormal handling of material roll modification, waste disposal, etc. in quality management. Real time scheduling for various unexpected situations that occur on site.

2. Process management
Design the process for the contract received by MES, and provide modification information when quality issues arise that require modification. Perform process approval when executing alternative processes during the production process.

3. Quality management
Develop corresponding quality inspection standards based on product technology. Conduct quality inspections on work in progress and provide quality handling suggestions for rolls with serious quality issues. Conduct quality inspection on the finished product and issue a quality judgment certificate. Statistical analysis of quality issues that arise provides a basis for improving the process.

4. Raw material inventory management
According to the recent raw material demand plan issued by the plan and the inventory of the raw material warehouse, request materials from the material center, inspect and store the received materials, organize the production of raw materials according to the ingredient list, and carry out ingredient outbound. The remaining materials are stored in the warehouse, and the waste from each machine is recycled. Regularly conduct inventory checks on raw material inventory.

5. Material tracking management
After the ingot is produced, the system will use the ingot number as the full tracking code to track the materials. Material tracking includes real-time information tracking and historical information recording of materials. Real time information tracking records the current position, status, weight, specifications, and other real-time information of the material roll; Historical information records the detailed processing of the material roll in each process, including historical process parameters, weight before and after the material roll, specifications, etc. In addition to production information, quality issues with copper coils are also recorded here, and relevant personnel can view the quality history of the coils to achieve comprehensive quality tracking and management.

6. Equipment and spare parts management
Equipment management maintains the equipment host ledger of the enterprise, formulates maintenance plans for each equipment, and records the maintenance and lubrication performance. Spare parts management refers to the management of spare parts such as rollers, milling cutters, crystallizers, as well as consumables such as lubricants and tools, recording the usage of spare parts and consumables, and providing a basis for cost accounting.

7. Job cost management
Job cost management calculates the cost of the enterprise based on data collected from other subsystems and secondary equipment. Based on the cost drivers of each task, allocate the task costs to machines, teams, and rolls to form various financial statements, which serve as the basis for the enterprise to make macro decisions.

The MES system collects information from the production process of the enterprise and processes the collected information to timely grasp the production arrangement plan, production task management, execution status of production tasks, and statistical information of the production process of the enterprise; Through advanced statistical theory and information optimization software, the collected production process information is analyzed and processed, enabling the MES system to effectively guide enterprises to allocate limited production resources, identify new economic growth points, adjust business strategies in a timely manner, effectively schedule production plans, and improve economic benefits.

Modern energy storage systems using lithium-ion batteries can provide excellent performance, but each battery must be closely monitored to ensure proper charging and avoid battery imbalance, overcharging, deep discharge, or critical temperature. This requires providing separate, isolated power supply voltage control circuits for each unit or unit array. For battery arrays with a nominal voltage of up to 48V, standard industrial DC/DC power converter modules that provide 500V or 1600V isolation barriers can be used to generate this power voltage.

But for higher power systems connected to AC power sources and providing energy storage capacity of hundreds or even megawatt hours, the voltage on the battery array can reach 600-800V and a solution with higher isolation barriers is required.

Low isolation capacitance enhances noise resistance
P-DUKE has a medical power converter series with a 5kV isolation barrier, even higher than the required 4kV. For this project, MPD30-24S12 was selected, which can generate the necessary 12V/30W power voltage from the common 24Vdc bus.

The input and output capacitance of a typical industrial 30W DC/DC power converter can reach up to 1500pF. When up to 200 converters are connected in parallel, the total capacitance between the battery unit (connected to the AC grid through a charger) and the 24V bus can reach 300nF, resulting in an AC leakage current exceeding 20mA. A current exceeding 10mA may cause serious electric shock and accidents.

The input and output capacitance of MPD30-24S12 is only 20pF, and the total capacitance after 200 converters are connected in parallel is only 4nF, with a leakage current of less than 1mA.
This very low capacitance also avoids transient or any noise coupling from the AC/battery side converter to the sensitive communication signals of the central battery management system.
Through this solution, the requirements for 4kV isolation and low leakage current have been resolved.

For communication throughout the installation, the central BMS controller uses a WiFi router and is powered by a 25W 53V power supply via Ethernet. According to the final installation, the power supply voltage can be generated by a 230Vac main power supply or an internal 24Vdc bus. For 230Vac, TSD30 series converters can be used. It also offers a Din rail version for easy installation in the controller rack.

Large battery storage systems benefit from the application of P-DUKE products:
The MPD30/MPD30W series is a series of 30W DC/DC power converters with enhanced 5000Vac isolation voltage, which can meet the requirements of medical applications. They have different input voltage ranges and provide single or dual output. This series complies with the 2MOPP standard, with an electrical clearance and creepage distance of 8 millimeters. This makes them suitable not only for medical devices, but also for other applications that require high isolation and extremely low input/output capacitance.

The TSD30 series is a ready to use AC/DC solution suitable for Din rail applications. Like the RCD30W series, it provides different output voltages and installation options for various applications.

As the Global Executive Vice President of Schneider Electric’s Systems and Services Business, Gao Feike’s goal for this trip is clear – for the energy transformation that is currently undergoing significant changes, he hopes to understand the new landscape reshaped by the global energy transformation through on-site visits and localized communication and close observation, especially the current application status of China’s electric vehicle charging and energy storage technology.

Recently, Gao Feike accepted an interview with First Financial, sharing his views on energy transformation, the challenges faced by current energy development, the opportunities hidden in China, and the emerging circular economy.

The global energy transformation is in its second stage, and the deep integration of digital and electrification technologies is the key to winning the battle

Gaofeike has a clear timeline in his mind regarding the global energy transformation process.

He believes that the global energy transition can be divided into three stages: the first stage is a significant increase in awareness, that is, the stage of starting to replace traditional energy with renewable energy; The second stage is the practical stage of applying new energy and large-scale electrification; The third stage is ten years later, when more emphasis is placed on systematic and balanced development. The global energy transformation has now entered the second stage with the goal of improving quality and efficiency.

In Gao Feike’s view, the biggest feature of the second stage of energy transformation is that it touches the demand side and reconstructs the relationship between electricity supply and consumers by changing the original energy supply mode. The power grid architecture originally designed for fossil fuels will be revitalized by various electrification and digital solutions, more in line with the demand for new energy generation, and a new market with highly flexible matching between energy supply and demand will be formed.

Gaofeike emphasized that the second stage is the beginning of truly realizing the process and demand side electrification transformation. There is a consensus within Schneider Electric that tapping into the potential for demand side regulation and continuously promoting the deep integration of digital and electrification technologies are key to winning the battle of energy transformation. Building a new type of power system is an important driving force and guarantee for China’s energy transformation and achieving the “dual carbon” goals. As an expert in the field of energy management, Schneider Electric believes that focusing on the energy demand side can not only better serve the supply side structural reform, but also provide more sufficient and flexible resources and impetus for promoting energy transformation due to its wide range of industries and high degree of marketization.

As for the third stage of energy transformation, Gaofeike is expected to arrive in about 10 years. Compared to the second stage, the third stage will focus more on the balance of the entire system. This does not mean that we should not start considering the establishment of a balanced and flexible power grid system now, but we must first achieve large-scale electrification.

China leads the global energy transformation with challenges and opportunities
“I am confident that China is in a leading position and plays a crucial role in the global energy transition.”
Gaofeike has a keen insight into the latest trends in China’s energy transformation. According to his observation, in China, new energy or “Electricity 4.0” has gradually begun to scale up and more energy storage systems have been introduced to balance the entire power grid. In 2023, China’s ability to build renewable energy is impressive, surpassing any other country in terms of construction scale.

As Gao Feike said, the installed capacity of renewable energy generation in China in 2023 has historically exceeded that of thermal power, with more than half of the world’s new installed capacity added throughout the year. This year’s Government Work Report further proposes to “deepen the energy revolution, control fossil energy consumption, and accelerate the construction of a new energy system.”.

In addition, the Clean Energy Market Monitoring report released by the International Energy Agency in early March this year showed that China is a leader in the global renewable energy sector, and clean energy technology continues to lead significantly globally. Multiple international think tanks and media outlets also believe that China is at the forefront of the world in the field of renewable energy, and its pace of replacing carbon based energy with renewable energy is faster than many experts had anticipated.

With the continuous promotion of high-quality development in China, energy is facing historic transformation and innovation opportunities. Traditional energy has been replaced by new energy, and energy needs to be deeply and widely integrated with information technology. The physical grid needs to become a smart grid, while also becoming a digital grid. Energy transformation is not only about low-carbon energy structure, but also involves the establishment of a new energy power system and new operating mechanisms, namely the energy system revolution.

Gao Feike stated that on the one hand, benefiting from its scale advantage, China’s investment in renewable energy is faster than the global average; On the other hand, China is also at the forefront of demand side transformation in the transportation sector. As is well known, the penetration rate of electric vehicles in China is high, and energy storage facilities are rapidly becoming popular. Therefore, large-scale testing of the “future power grid” can be conducted here, and new solutions can be created in a variety of application scenarios. In Gao Feike’s view, this is an excellent opportunity for China.

Of course, China and even the world face the challenge of finding a suitable supply chain and sufficient supply capacity for energy transformation. To truly achieve decarbonization, electricity consumption will double, which requires building a complete industrial chain. In the future, every country will pursue electrification, which means that each country needs to ensure that it has sufficient production capacity.

Focusing on power grid construction, Gao Feike believes that the current challenge is to provide power or strengthen the power grid in areas with previously low electricity demand. For example, nowadays, fast charging stations along highways take 20-30 minutes to charge cars. However, during the Spring Festival travel period in China, there may be concentrated outbreaks of charging demand in some areas. This requires strengthening power grid construction and energy storage utilization, creating a high resilience and flexibility power grid to meet the charging needs of different regions and different time periods.

In addition, the other two challenges of power grid construction are the correct use of energy storage and DC systems, as well as optimizing the output of the power grid at every moment. He believes that these challenges are not insurmountable, but require execution. Schneider Electric has a large number of products and solutions related to strengthening the security and resilience of the power grid, which can ensure the safety of the power grid and improve the efficiency of distribution management.

In his view, the Chinese market is very unique for Schneider Electric, and the model of working together with local partners for development can be considered unique in the global market. We have confidence in the local supply market, and Schneider Electric will mainly focus on core technology and digital innovation, which can help our partners deploy solutions. Through the ecological network established with many partners, Schneider Electric will integrate technology and digital elements into their solutions, thereby jointly serving the market.

Returning to China after four years, China’s level of innovation has also left a deep impression on Gaofeike. During his visits to enterprises, he witnessed China’s innovative capabilities in cutting-edge fields such as energy storage and electric vehicle charging, as well as the latest achievements of Schneider Electric’s collaboration with local Chinese partners to explore innovation boundaries. In early March, Schneider Electric reached a partnership with Shuimu Mingtuo (Damao) Hydrogen Energy Technology Co., Ltd. As Schneider Electric’s world’s first full process optimization business from green electricity to green hydrogen and then to green ammonia, both parties will use digital twin technology to connect the power and process flow, and explore the full process optimization from green electricity to green hydrogen and then to green ammonia through dynamic joint simulation and simulation of electric hydrogen and ammonia.

In the words of Gao Feike, “such a heavyweight project has landed first in China. It not only recognizes Schneider Electric’s cutting-edge exploration capabilities, but also demonstrates the enormous potential of China’s renewable energy industry.”. In the eyes of him and many members of the management team who came to China this time, China’s introduction of visa free policies for many European countries is also a sign of China’s active openness and promotion of global cooperation. With these as footnotes, everything is possible for Schneider Electric and China’s future.

Preface:
Emerson, a giant enterprise in the field of industrial automatic control, has always been a backbone of industrial control hardware and software. As one of Emerson’s important products, intelligent platform discrete control products hold a large share in China.

However, due to the constantly changing market demand and rapid technological progress, Emerson’s intelligent platform products are also constantly evolving. In this situation, we need to have a more comprehensive and in-depth understanding of intelligent platform products, including discontinued and on sale models, as well as the programming software and communication protocols they use.

This article will introduce the history and development of Emerson’s intelligent platform, provide a detailed explanation of how the intelligent platform went from GE to Emerson, provide a detailed explanation of its discontinued and commercially available intelligent platform models, and test the communication protocol of the intelligent platform through experiments. At the same time, we will also discuss the programming software of PLC and how to address the security threats of intelligent platforms in practical applications.

Its products can be used in various industrial fields including automation, process automation, national defense, automotive manufacturing, communication, medical, and aerospace.
GE Fanuc is the world’s first to launch the PAC system as a new generation control system.

What is the difference between PAC and PLC based on historical background analysis and multiple occurrences of PAC?
The main difference between PACs and PLCs lies in the firmness and reliability of the product. Specifically, the performance of PLCs mainly depends on hardware, and the execution of programs mainly relies on hardware chips, which limits the functional prospects and openness of the system. PLC is a proprietary operating system, and compared to general real-time operating systems, its reliability and functionality are limited, which leads to the specificity and closure of the overall performance of PLC.
The performance of PACs is based on their lightweight control engine, using a standard, universal, and open real-time operating system, embedded hardware system design, and not relying on hardware chips. Their software performance is superior to PLCs The performance of PAC is based on its lightweight control engine, standard, universal, and open real-time operating system, embedded hardware system design, and backplane bus.

SafeMove2 is ABB’s second-generation safety controller product for robots, aimed at ensuring personnel and equipment safety, promoting human/robot collaboration, and providing users with lean, flexible, and more cost-effective robot solutions. Its powerful configuration tools greatly reduce debugging time and provide flexible safety features such as rated speed and position monitoring, enabling dangerous applications such as X-ray inspection and laser cutting.

For the safety range of Safemove2, nodes can be manually added based on the layout in RobotStudio, and specific positions can be adjusted manually by dragging and dropping.

Usually, the safety range should be based on the actual operating trajectory of the robot, set as small as possible, that is, the safety range only needs to include the robot’s trajectory working range (including end tools, upper arms, etc.).

Safemove2 provides the function of automatically generating a safe range based on the robot’s trajectory. The effect is as follows.

Specific usage method:
1. Create robot trajectories in robotstudio.
2. Enter the safemove2 settings interface and click on step 1 in the following image: Record Simulation
3. Click on the simulation trajectory to play (step 2)
After the simulation is completed, the safety zone and safety range icons become operable.
5. Click on “Safe Zone” and select the tool position monitoring. If the tool and elbow joint are selected (provided that the body geometry wrapping has been set), the minimum area based on the tool wrapping and body wrapping motion range will be generated.

If you choose tool only, only the range based on the tool package will be generated.

It can also automatically generate maximum speed monitoring and configuration of each axis range (safety range) for TCP and 3-axis monitoring points.

As the core component of robot driving applications, the development of power semiconductor devices has always been a focus of industry attention. As a pioneer in modern power semiconductor devices, Mitsubishi Electric has always taken it as its responsibility to provide high-precision and reliable products to the market, striving to meet and lead new market demands with cutting-edge technology.

It is reported that in the future, robot servo drive technology will develop towards two major trends – multi axis servo drive solutions and high power density design. This also means that the market will require power modules with more features, lower losses, more compact appearance, and higher integration level.

Therefore, Mitsubishi Electric has launched three power module solutions for different power ranges of servo drives: CIB-IGBT solution, IPM solution, and DIPIPM solution ™/ DIPIPM+ ™ Plan.
The 7th generation IGBT CIB solution launched by Mitsubishi Electric has the characteristics of integrated packaging (SLC), ultra-low stray inductance, and excellent thermal cycling life. It uses a single substrate to reduce binding lines; The thickness of the copper sheet has increased, optimizing the wiring width; Using DP resin to reduce mechanical stress between binding wires and silicon wafers; Removed the welding layer and removed the weak points of thermal cycling.

At present, Mitsubishi Electric Semiconductor has launched an IPM module based on the 7th generation IGBT chip technology, which integrates a driver IC inside the module to adjust the driving current to change the dv/dt under different currents, making it easy to design system EMI; Collaborate with optimized driver ICs to identify fault types and facilitate system design and debugging; Adopting SLC packaging technology and optimizing the packaging materials of modules to improve module lifespan and reliability.

“The 7th generation IPM has low loss, low EMI noise, identifiable fault signals, and long thermal cycle life, making it particularly suitable for servo drive of high-end multi axis robots,” Director Song summarized.

Among them, the G1 series is compatible with the G series IPM packaging size, with built-in 7th generation IGBT/FWD chips with lower losses, and adopts a new packaging technology for better reliability; In addition, the new driver circuit further reduces losses and EMI noise. The control terminals of the G1 series are compatible with the G/L1 series and can use the same interface circuit. The main functions are the driver circuit and protection circuit.

In terms of packaging technology, the G1 series of the 7th generation IPM has a thinner and more compact packaging, with a volume reduction of 18-31%; A-type packaging is more suitable for flexible layout applications, such as the G1 series which offers two types of terminals to choose from.

In order to meet the application needs of the frequency conversion market (high reliability, low cost, miniaturization, etc.), Mitsubishi has developed a series of DIPIPMTM products. It is a dual inline packaging IPM with built-in HVIC, making its peripheral circuits simpler and cost saving. It is now widely used in products including household appliances, small frequency converters, industrial servos, etc.

It can be said that Mitsubishi Electric Semiconductor is a pioneer in die casting die packaging of IPM products. For different applications, Mitsubishi Electric continuously optimizes power silicon wafers, has the widest product line, and has accumulated rich experience in IPM. Its products maintain high cost-effectiveness while ensuring high reliability and low failure rate.

Since 1921, Mitsubishi Electric has been continuously launching generation after generation of products with better performance and higher cost-effectiveness, focusing on five major application areas: variable frequency household appliances, industry, new energy, rail traction, and electric vehicles, with product research and technological innovation as the original intention. Now, Mitsubishi Electric’s DIPIPM is being developed and launched ™️ It has become an indispensable and important component of the field of variable frequency household appliances, and its HVIGBT module for high-speed locomotives has also become an industry recognized standard.

As a pioneer in modern power semiconductor devices, Mitsubishi Electric is driven by a spirit of continuous innovation, empowering through technology and speaking with products. Under the goal of improving production efficiency, providing high-quality products, and meeting environmental development needs, Mitsubishi Electric will continue to match the development needs of China’s industrial automation transformation and upgrading with finely crafted products.

Starting from the end of the century and emerging in Huazhi – entering a new stage of green energy: Since the early 20th century, Norshepin, Sweden has been a gathering place for major turbine and pump manufacturers. More than a hundred years later, a small company called Againity joined them in 2013, and now the company is disrupting the energy production sector and pursuing a greener future.

The story of Againity begins at the end of the day, and everything stems from the personal dreams of its founder David Fryker å s. In order to fully utilize the energy loss in industrial processes, he established Aging. This company has found a method to convert hot water into electricity and district heating, with a system efficiency of up to 99%.

Againity’s patented ORC turbine can fully utilize various low-temperature waste heat and convert it into stable and renewable electricity. Both hot water boilers in heating plants and waste heat from industrial processes can become sources of energy for their power generation. Even if the temperature difference is only 30 degrees Celsius, it can still drive this special type of ORC turbine to generate electricity. Moreover, Againity’s ORC turbine power generation system adopts a modular design, with electrical power ranging from 100kWe to 560kWe.

“Network security is crucial in these applications, and ABB’s PLC can provide a very high level of security protection,” said Rickard Haglund, Automation Manager at Againity

The reliable operation of all equipment components is crucial, as ideally, the turbine should always remain in operation, and in the event of a run out of hot water supply, the components can limit their performance to prevent shutdown. The CPU of the AC500 PLC fully utilizes its integrated floating-point unit and uses a sixth degree polynomial to continuously perform advanced thermodynamic calculations, ensuring the continuous operation of the turbine and monitoring overheating and underheating conditions.

Rickard added, “ABB’s programming software provides tools for simplifying programming. It is important for us to download program changes online as they can be completed during operation without the need for downtime.”

Automation Builder uses structured text for advanced computational programming, and programs the main program in Continuous Function Diagram (CFC) to provide an overview of the entire process, making it an ideal tool for Agarity ORC turbines.

Againity’s ORC turbines can be deployed in different locations, such as treatment plants containing residual gases, regional heating stations, etc. Nowadays, many Aging turbines have been put into operation in Sweden, Norway, Finland, Poland, Estonia, Lithuania, and Greenland.

The use of DCS process alarm classification control plays a crucial role in the safety of the site. According to relevant data surveys, the selection of alarms has a significant impact on the level of alarm safety factor. When using this technology, attention should be paid to the selection of alarms.

This article proposes several principles for selecting alarms through the study of different control systems, ensuring that alarms can fully play their role in the system.

The hierarchical control technology can ensure that alarms in different areas are independent. Different alarms are used for alarm monitoring in each area, which can ensure timely alarm in case of abnormal situations within the detection range to attract the attention of operators.

DCS process alarm classification control technology can effectively improve the safety of the operation site, effectively ensuring the safety of construction personnel and enterprises. This article is based on the concept and characteristics of DCS, and studies the application of toxic and harmful gas alarms and key operating parameter alarms, in order to provide reference for scholars in this field.

1. DCS multi-layer hierarchical control system

The basic design concept of DCS is to adopt the idea of decentralized control, centralized operation and management, and achieve a multi-level hierarchical control and cooperative structure. At present, it is mainly used in fields such as metallurgy, power, and petrochemicals.

DCS is a system that implements multi-layer hierarchical control, which has two basic hierarchical links during use: on-site control unit and operation station.

DCS basic grading process

● On site control unit:

A control system that is used near the site and is far away from the control center, and can monitor and control the site based on the DCS’s own structure. The use of on-site control units requires the preparation of different devices, such as configuration plugins, which are configured according to the requirements of the system with corresponding central processing unit plugins, power plugins, and communication plugins, laying the foundation for later hierarchical control;

Redundancy configuration is one of the important links in hierarchical control systems, and during the configuration process, it is necessary to implement redundant configuration for host plugins, power plugins, and communication plugins; Implementing on-site hierarchical control and monitoring requires adding DCS to different hardware to ensure the reliability of hierarchical control.

● Operation station:

The operation station records and displays different data in the control system, which is a place for displaying human-computer interaction. Commonly used operation stations include host control, display devices, and keyboard input devices, which are mainly used for manual operation recording and feedback. It mainly realizes various important functions such as displaying different data, alarms, and operations.

2. Application of DCS process alarm classification control technology

Toxic and harmful gas alarm

Through the study of different DCS process alarm classification control technologies, it has been found that the DCS devices used in current on-site work mainly detect and alarm toxic, harmful, and flammable gases. When these gases are detected, an alarm will be triggered. The alarms on the market have diverse characteristics, and to ensure the normal operation of DCS, standardized alarms should be used.

In the process of selecting alarms, the following rules should be noted:

● It must be able to provide power supply for monitoring toxic and harmful gases and other connecting components;

●Being able to emit appropriate alarm signals after detecting toxic and harmful gases until someone discovers them, greatly improving the effectiveness of the alarm function;

●The range of combustible gas monitoring should be within the normal explosion range;

●Adapt to the concentration and measurement range of toxic and harmful gases, ensuring the detection of harmful gases within the normal range;

●Indicating alarm equipment is quite important and the key to determining whether it can alarm correctly. In the process of selection and purchase, alarm equipment with fire protection and interlocking protection functions should be selected;

●The alarm should have independent monitoring and alarm functions, ensuring that each alarm only monitors toxic and harmful gases within its scope of responsibility;

●The installed alarm should have a continuous alarm function. If toxic and harmful gas leaks are found during use, the alarm function should be activated. When the concentration decreases, the alarm also needs to continue to sound to ensure timely detection of toxic and harmful gas leaks.

Alarm is the key to alarm classification control technology. In the use of modern DCS process alarm classification control technology, responsible personnel can select and use alarms based on the above principles to ensure the safety and standardization of the control site.

Key operating parameter alarm

Each parameter in the DCS process alarm classification control technology using computer control systems needs to be strictly set and controlled. If the parameters are too high or too low, it will cause incalculable losses to the site. It is required to achieve the accuracy and standardization of alarm parameters through strict data analysis when setting alarm parameters.

When setting the alarm mode, a pop-up window or voice alarm can be used to effectively increase the attention of staff, provide the best solution time for staff, and avoid more serious accidents and losses.

Pop up alarm mode

When setting up pop-up alarms, the operator achieves the accuracy of the alarm process through on-site monitoring and control. The pop-up window should be set in the center position of the control display page, making it convenient for the staff to pay attention to the location of the alarm and the direction of the problem at the first time, providing more preparation time for the operator to effectively solve the problems that occur during the process;

● Voice alarm method

The use of voice alarm function requires staff to record the voice alarm in advance according to possible situations on site, and play the alarm information through the computer’s voice output function.
