Why do manufacturing factories need production management MES systems

Why do manufacturing factories need production management MES systems

2024-04-22

1、 Production management needs and pain points in the manufacturing industry

The increasingly fierce market competition and the increasing demand for product diversification from customers have led to a shortened product lifecycle. Enterprises need to achieve cost reduction, efficiency improvement, and quality improvement through intelligent manufacturing to improve their rapid response capabilities and core competitiveness.


2、 The specific pain points in the process of production management are as follows:

1) Production progress is opaque

Enterprise management personnel are unable to understand the actual production situation in real time, and the effectiveness of the production plan issued is difficult to ensure, which leads to unpredictable delivery cycles and frequent order delays.

2) Difficulty in production cost control and accounting

The production process data is missing, problems are not discovered in a timely manner, resulting in waste, and the root cause cannot be traced; Unable to collect and calculate the costs of each production process, and unable to obtain real-time dynamic cost information; The work efficiency of workshop workers cannot be measured, and labor costs cannot be accurately grasped.

3) Difficulty in adjusting production plans

In the production process, there are factors such as order insertion, cancellation, batch changes, and delivery time changes that require quick adjustment of the production plan. Without a system, such adjustments are often difficult to respond quickly.

4) Difficulty in production scheduling and low efficiency

Due to the long time required for equipment mold replacement or other production preparation, ineffective consolidation and use can affect production efficiency.

5) Difficulty in managing and controlling complete sets of materials

In order to improve production efficiency, enterprises often do not wait until the entire product is complete before starting production. They will go to the process to complete production in advance, which puts higher requirements on materials to be delivered on time and in quantity. However, many enterprises often encounter material complete problems due to the inability to timely understand abnormal material consumption and other situations, resulting in production shutdowns.

6) Difficulty in tracing product issues

A large amount of paper is neither convenient to access nor environmentally friendly. Customers have traceability requirements, making it difficult to accurately and quickly query all relevant traceability data for each batch of products, and historical production data cannot be effectively utilized.

7) Difficulty in establishing a quality system

Unable to conduct online testing, statistics, analysis, and presentation of product quality indicators

8) The production process is difficult to prevent errors, errors, and leaks

Faced with the production mode of multiple varieties and small batches, materials, personnel, process parameters, processing requirements, etc. are constantly changing, often resulting in quality and efficiency losses due to personnel operational errors.

9) Delayed handling of emergencies

When abnormal events such as equipment failures, material defects, production line shortages, processing abnormalities, power abnormalities (water and electricity shortages), safety accidents, etc. occur, it is difficult to quickly feedback and handle them.

10) Difficulty in outsourcing control

The production progress of outsourced factories is opaque, processing costs are difficult to verify, and the reasons for losses are difficult to track.

3、 The management scope involved in MES system:

MES is a system aimed at the execution workshop, which falls within the scope of MES from the issuance of plans in ERP to the receipt of finished products. The core elements involved in this include "human, machine, material, method, environment, measurement, and energy".

People refer to the personnel who manufacture products, including production personnel, planners, dispatchers, quality personnel, warehouse managers, equipment managers, etc. They play an important role in executing production.

Machine refers to production equipment, fixtures, underlying control systems, and tools required in production, and is the main force of production.

Materials refer to the raw materials required for production. The completeness, procurement, use, transportation, and preservation of materials are all related to the continuous operation of production.

Law refers to the methods used in the production of products, which can also be summarized as production processes.

Environment refers to the environment in which products are produced, including temperature, humidity, lighting, cleanliness, etc.

Measurement refers to whether the key points of measurement and the methods used for measurement are standard and correct.

Energy refers to the energy consumed in the production of products, such as electricity, water, etc.

4、 The core process of MES system

The process from obtaining production plans from the ERP system to the completion and receipt of final products belongs to the scope of MES, and how MES drives production through core data.

Understanding the difference between MES and ERP in one article

Understanding the difference between MES and ERP in one article

2024-04-10

The concepts of MES and ERP:

The MES (Manufacturing Execution System) system is a manufacturing execution system located between the upper level planning management system and the direct industrial control system of the production process. It is a management information system aimed at the workshop level, which can optimize the entire workshop manufacturing process, collect real-time data from the production process and make corresponding analysis and processing. It interacts with the planning and control layers to achieve full integration of enterprise information.

ERP (Enterprise Resource Planning) system is an enterprise resource planning system, which is built on the basis of information technology and provides a management platform with systematic management ideas to provide decision-making and operational means for enterprise decision-makers and employees. It is an information system that integrates enterprise management concepts, business processes, basic data, human and material resources, computer hardware and software.


The difference between MES and ERP:

1. Different management objectives

The focus of ERP is on finance, which means planning a company's resources from a financial perspective. The related modules are also centered around finance, and the final management data is centralized on financial statements. The focus of MES is on manufacturing, which aims to manage product quality, on-time delivery, equipment utilization, and process control. Because different enterprises have different management priorities, the focus is also different when choosing the composition of information systems. Group companies, commercial enterprises, logistics enterprises, etc. place more emphasis on ERP management, while manufacturing enterprises require MES management more.

2. Different management scope

The management scope of ERP is relatively large, involving planning levels such as procurement, finance, sales, production order management, shipping management, and finished product warehousing plan control. It mainly shares and utilizes enterprise resources effectively, enabling reasonable allocation and utilization of enterprise resources in various aspects such as procurement, storage, production, sales, personnel, finance, and materials, but it is not detailed and specific enough. MES management is more detailed than ERP, mainly involving workshop work order distribution, process error prevention, product lineage, SPC quality analysis, equipment data analysis, process traceability, and other execution levels. It can be more detailed to each manufacturing process, issuing tasks, controlling execution, data collection, and on-site scheduling for each process.

3. Different management functions

In addition to financial management, human resource management, customer relationship management, and other functions, the main function of ERP in manufacturing management is to prepare production plans and collect production data. In addition to refining production plans and collecting production data, MES also has batch level production control and scheduling management functions, such as batch level process flow changes, validation control of manufacturing equipment, personnel and materials, batch splitting and merging, and on-site scheduling functions such as batch production order changes.

4. Different implementation methods

ERP mainly adopts the methods of filling out forms and form transfer to achieve management. The manufacturing tasks received on site are communicated through forms, and on-site manufacturing data is also collected by filling out forms. MES adopts an event based approach for management, monitoring changes in production orders and on-site manufacturing conditions. Through the built-in WIP (Work in Process) engine in MES, relevant events are immediately triggered, requiring relevant personnel or equipment to take corresponding actions. Therefore, MES can reduce data input work, achieve on-site command issuance and data collection through information systems, reduce errors, and improve timeliness.


5. Different time periods

It is precisely because MES adopts the WIP (Work in Process) engine to drive management, which can achieve real-time on-site management: superior production plans and scheduling can be immediately reflected in the job interface of the manufacturing site, and on-site production data and abnormal situations can also be real-time reflected in the supervision interface of the management position, providing a two-way production information flow between the upper and lower levels of the enterprise, making timely scheduling possible. The form format of ERP inevitably has an input cycle, and the managed data is based on weekly and daily time cycles, making it difficult to effectively control on-site execution in real-time. This so-called "information black hole" exists in the manufacturing process, which has an increasingly unfavorable impact on the management and control of the manufacturing process.

6. Different technical requirements

ERP mainly processes plan data, with a small amount of data that does not require interaction with underlying hardware, making it easy to manage in a centralized manner. During implementation, the plan process is relatively fixed. The data granularity of MES is small, the data volume is large, and it is closely related to the process, workshop management process, and automation level of the factory. There are significant differences in implementation among different enterprises, and it is necessary to continuously adapt to the changes in workshop management mode. In addition, MES systems directly record production process data, which requires higher reliability and stability than ERP systems.


The selection of MES and ERP

For enterprises that do not have the conditions for integrating MES and ERP, the choice of MES or ERP depends on the business priorities and development stages of different enterprises. If the enterprise's business grows, the main focus is on continuously optimizing processes. MES, which manages manufacturing processes such as inventory, production, and scheduling, is the most suitable.

Adding other additional modules to the combination requires paying a higher ERP price, and ultimately establishing a system focused on business finance and record keeping rather than production is meaningless. At the same time, the complexity of an ERP system requires enterprises to have IT resources that can support it.

ERP is more suitable for large and medium-sized enterprises that have already been commercialized and have their own IT teams. Continuous business growth is no longer the most critical factor. For smaller and constantly developing enterprises, especially manufacturing oriented enterprises, the role of most ERP systems in production planning and control is very limited.

Due to its minimum header size of 2Byte, it is a very compact and lightweight protocol that can be used in devices with strict memory and running speed limitations, as well as in communication environments with narrow bandwidth.


Scalable

Due to the limited resources required to implement a communication environment, it can be implemented on various devices ranging from small IoT devices to high-performance terminals, thereby achieving highly flexible system construction.


reliability

In MQTT, a mechanism can be implemented to communicate based on levels in unstable communication environments, such as reducing the time required for IoT devices to reconnect and setting the reachability of communication.


The Security of MQTT Protocol

Protecting the system from various attacks and threats is a crucial element when building IoT systems using MQTT. It is recommended to use SSL certificates and passwords to implement ID, authentication, and licensing between the client and proxy.


New support for BACnet communication

The CONPROSYS IoT gateway is equipped with new BACnet server, client, and router functions, making it possible to achieve IoT of building equipment.


Equipped with BACnet communication function

BACnet is a communication protocol standard for networks used in intelligent buildings. In various fields such as air conditioning equipment, lighting systems, electrical equipment, security and disaster prevention equipment, and elevators, it is possible to build a system that can connect and monitor all equipment through a common interface, even products from different manufacturers. The CONPROSYS M2M Gateway supports the BACnet IP protocol and is equipped with server communication and client communication capabilities.


Server communication function

This is the function of providing internal information of IoT gateway to BACnet clients by using BACnet object types. It can integrate devices and sensors that do not support BACnet into building management systems that support BACnet communication.


Client communication function

This is a function of collecting building equipment (BACnet server) information, converting it into different communication protocols such as MQTT, and providing information to the higher-level system. It can build a system that integrates dispersed building equipment information through the cloud and remotely monitors it. In addition, it can also convert building equipment that supports BACnet to other communication protocols such as OPC UA or MTConnect, and integrate with factory equipment systems.


What is BACnet

BACnet (Building Automation and Control Network) is a communication protocol standard used for building networks. It is used to control the air conditioning, lighting, electricity, security, disaster prevention, elevators, etc. inside the building. In 1987, various groups related to the BA (Building Automation) system established guidelines at a meeting, based on the ANSI/ASHRAE Standard 135-1995 developed by the American Society of Heating, Refrigeration, and Air Conditioning Engineers in 1995. BACnet was used as a protocol for the BA system in 2003 and was specified in the international standard specification ISO16484-5.

The Electrical Equipment Society of Japan has developed Japanese standards (IEIEJp, IEIEJp-A) that have been extended to Japanese specifications. Therefore, there are three protocols, including ASHRAE BACnet, which includes standard specifications.

BACnet includes the "BACnet IP" protocol for communicating BACnet services over Ethernet, as well as the "BACnet MS/TP" protocol using EIA-485 (RS-485) as the physical layer for data transmission.


What is OPC UA

OPC UA (OPC Unified Architecture) is an open international standard specification developed for the exchange of safe and reliable data in industrial automation and other fields such as production factories and plant equipment. The OPC Foundation was published in 2008 and has since been internationally standardized as IEC 62541.

In addition, it is highly integrated with the international standard IEC61131-3 of PLC, and can be easily connected while maintaining the reliability between manufacturing site (FA) information and higher-level monitoring and control systems (SCADA) and production management systems (MES). Therefore, it has been adopted in many industries such as the communication standard specification PackML (ANSI/ISA-TR88) for packaging machines, EUROMAP for injection molding machines, and umati for machine tools. The German Mechanical Industry Alliance (VDMA) is developing a communication standard called "OPC UA for Machinery", which integrates specifications developed for different industries and aims to become the foundation for all mechanical devices.


The characteristics of OPC UA

Scalability

By using OPC UA, unified and scalable configuration of the system can be achieved from embedded systems to mainframes.


Interconnection

Traditionally, industrial equipment and control devices typically use communication standards unique to manufacturers, making it difficult for the entire system to work together. OPC UA can seamlessly connect from the controllers used for control in the factory to monitoring systems, production management systems, etc.


Security

Recently, safety measures for factory areas and equipment have become a topic of discussion. OPC UA ensures the security of messages between OPC UA Server and Client by using Secure Channel, making it easy to achieve secure communication between devices.


What is MTConnect

MTConnect is a standard communication protocol for machine tools developed by the MTConnect Association. The development of this protocol aims to enhance the data acquisition capabilities of devices and applications, and reduce integration costs. Centered around the United States, many large manufacturers have adopted this standard and it is highly regarded as a future standard specification.


The characteristics of MTConnect

Open Protocol

Traditionally, when using machine tools from multiple companies, it is necessary to develop software that meets the unique standards of each company. However, since MTConnect is an open protocol that uses standard Internet technologies such as HTTP and XML, the software for conversion can be installed relatively easily.


No usage fee

As MTConnect has no usage fees, there is no need to pay licensing fees to the MTConnect Association. In addition, companies that agree to the license agreement for MTConnect can also integrate MTConnect into their own company's products.


Generalization of data structures

MTConnect specifies the data structure for various types of data obtained from machine tools, such as spindle load, shaft speed, alarms, etc., according to their respective data types. User enterprises can easily compare and analyze the same type of data without worrying about data structure issues when connecting devices from different machine tool manufacturers.

Exploration of DCS Process Alarm Grading Control Technology

Exploration of DCS Process Alarm Grading Control Technology

2024-02-26

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.
