The implementation of enterprise informationization and improvement of management and control are the inevitable choices for companies to face increasingly fierce market competition. Implementing information systems such as Enterprise Resource Planning (ERP) alone cannot fully improve the level of informationization of enterprises. Enterprises need solutions that are integrated from the control layer, execution layer, and plan management to achieve information and knowledge sharing. Global optimization. TiSNet is an excellent process control system that has been proven through practical application in the field of process control. TiSNet's comprehensive solution for process enterprise informationization can help process companies to achieve integrated and integrated informationization from the control layer, execution layer, and plan management layer.
AMR (Advanced Manufacturing Research), a US advanced manufacturing research organization, introduced a three-tiered enterprise integration model (Figure 1) in 1992 through a survey of a large number of companies: planning management, mainly through ERP/MRPII systems; the manufacturing executive layer, responsible for the workshop Production management is implemented by the MES (Manufacturing Execution System) system; the control layer is controlled by the control system for equipment level control, monitoring and data acquisition.
ERP can handle what happened yesterday (for historical analysis), and it can also anticipate and deal with events that will happen tomorrow, but it often leaves an irregular gap with events that are happening today. MES is properly integrated with the control layer. The plan management provides real-time data and information for the production process and manages the execution of production.
For the process industry enterprises, the control layer is the basis and the source of data for production actual conditions. A good grasp of the actual production situation is conducive to the decision-making analysis of the plan management, and timely adjustment of the strategy to respond to the rapid changes in the market. Therefore, an information-based comprehensive solution based on the control layer can better help enterprises achieve comprehensive informationization and improve management level and production efficiency. 
Figure 2 shows the main functional structure of TiSNet. The real-time database is the core of the entire system. Real-time data comes from a real-time database. Historical data is obtained by collecting real-time data. One of the characteristics of TiSNet is the distributed real-time database. The real-time data is distributed on each operating terminal instead of being stored on a single server. That is, TiSNet works in a serverless mode, which avoids system crashes due to server crash and improves the system. Stability.
TiSNet has a self-check function that can display the status of all nodes in the system and the network status of the entire system, and can view the board information of each online XCU, XCU memory usage and CPU load, XCU software date, convenient System maintenance.
The XCU broadcasts the real-time information of the global point on the Internet in broadcast mode. The real-time data broadcast on the Internet can be obtained through the interface provided by the system.
TiSNet process control, on the one hand through the configuration of the engineer station, the configuration file is downloaded to the XCU, XCU according to the configuration instructions for data acquisition and control, etc.; on the other hand through the HMI send operation or configuration instructions to the XCU, The XCU then executes the command action and the command uses a point-to-point peer-to-peer transfer method.
In addition, TiSNet supports online configuration, provides OPC interfaces, supports GPRS, online video and more.
iSNet has high reliability, high degree of modularity (whether from hardware or software can be assembled into various practical applications based on user requirements), high degree of openness and integration (according to the OPC specification, providing OPC services and other data interfaces )specialty.
The above characteristics enable TiSNet to provide enterprises with an overall solution from the control layer to the planning layer, to optimize the efficiency of the enterprise, improve the level of enterprise management, and quickly respond to market changes, thereby creating maximum value for the company. 
The establishment of an MES system integrated with the planning management layer on the basis of the entity control layer is more conducive to the realization of the enterprise's overall integration and the optimization of enterprise processes.
Architecture Figure 3 shows the architecture of a TiSNet manufacturing company's comprehensive solution. It is divided into the planning management and manufacturing execution layer and the entity control layer. The planning management and manufacturing execution layer is supported by the intranet. ERP, PDM (Product Data Management) and OA (Office Automation) belong to the planning management layer, and MES belongs to the manufacturing execution layer. The upper user directly accesses the planning management and manufacturing execution layer through the client to perform business operations. Manufacturing Execution (MES) and Program Management (ERP, PDM, OA) enable the integration and optimization of information and business processes. 
Manufacturing Execution (MES) is the bridge and link between planning management and physical control. Through the integration with the entity control layer, the dynamic information of the production is obtained, processed and optimized. Through the integration with the planning management team, the company obtains production plan information and guides the production process to the functional characteristics of the TiSNet-based process industry comprehensive informatization solution, and feeds the actual production information back to the planning management to assist decision-making. The OPC Server runs on the entity control layer and is connected to the real-time network on the one hand; on the other hand, it is connected to the intranet through the firewall.
The OPC Client runs on the enterprise LAN and exchanges information with the OPC Server to obtain real-time data processing and write it to the MES database. On this basis, the analysis and optimization of the production process and equipment operation status can be realized; and the application based on the network can also be realized: graphic display, trend, alarm, report, equipment management, production scheduling, and quality control.
Functional Characteristics Figure 4 shows the functional characteristics of the TiSNet-based process industry comprehensive informatization solution. The entity control layer is the Xinhua TiSNet series control system, which interacts with the manufacturing execution layer through the OPC interface. The physical control layer controls the production process. The manufacturing execution layer acquires the dynamic information of the production process through integration with the entity control layer, analyzes and optimizes the production process, and the manufacturing execution layer integrates with the planning management layer (ERP) to acquire production task information. The main functions of the manufacturing execution layer include: planning and scheduling, data conditioning, material balance, production management, operation management, equipment management, performance management, storage and transportation management, batch number tracking management, laboratory information management, and production status network monitoring. The planning management team mainly implements production planning management, human resources management, financial management, procurement/material management, and sales management. An enterprise information portal is established on the basis of plan management, manufacturing execution layer, and entity control layer, and organic integration is achieved through data interfaces and supply chain management (SCM), customer relationship management (CRM), and office automation (OA).
The comprehensive informatization solution for process industry based on TiSNet lays a solid foundation for the enterprise to fully realize information integration, process integration, and optimization of business processes. It will surely play a huge role in promoting business process optimization and improving management and control.
